This document discusses botany and plants. It describes how Genesis says God created plants with seeds. It outlines the plant kingdom and the main parts of plants - roots, stems, leaves, fruits and flowers. It goes into detail about roots and stems, describing their functions and root systems. It also describes leaves in depth, including their parts, arrangements, types, functions in photosynthesis, and special leaf variations. It emphasizes God's wisdom and design in creating plants before humans and animals.
Plants are vital for life on Earth. They convert sunlight into food through photosynthesis, produce oxygen, regulate climate, provide habitats for other organisms, and give us food, materials and medicines. Plants live in almost every habitat and maintain the balance of gases in the atmosphere. They come in a huge variety and have complex structures adapted for reproduction, growth and survival.
Here are the key parts of a seed:
- Seed coat: A protective outer covering that protects the embryo and stores food. Seed coats come in many colors, textures, and thicknesses depending on the plant.
- Embryo: The tiny new plant inside the seed. It contains a miniature stem, leaves, and sometimes a root tip.
- Cotyledons: The first pair of leaves inside the embryo. Cotyledons contain stored food for the embryo to use as it begins to grow into a seedling.
- Endosperm: A tissue inside some seeds that contains food reserves like carbohydrates, proteins, and fats. The endosperm provides nourishment for the embryo as
The parts of a plant and their functionsIrfanfahrizza
Plants have five basic parts - leaves, stems, roots, flowers, and fruit - that each serve important functions. Leaves produce oxygen through photosynthesis and release water through transpiration. Stems transport water and nutrients throughout the plant via vessels. Roots take in water and minerals from the soil using root hairs. Flowers function to sexually reproduce the plant species to ensure its continuation. Fruits contain seeds and can either have one seed like mangoes or multiple seeds like guavas.
Seedlings grow from seeds and contain the food needed for the young plant to grow. Flowers produce seeds which start the next generation. Pollination occurs when pollen is transferred between flowers by insects, animals, wind or water, allowing seeds to form. Non-flowering plants grow directly from seeds into trees or shrubs without producing flowers.
NEW STANDARDS 6th grade Plants1: classification & processesRobin Seamon
The document provides an overview of plant classification and processes. It divides plants into two main categories: nonvascular and vascular plants. Nonvascular plants include mosses and lichens. Vascular plants are further divided into seedless plants like ferns and seed plants like gymnosperms and angiosperms. It describes the characteristics and examples of these different types of plants. The document also covers plant structures, functions, and processes like photosynthesis, transpiration, and the plant life cycle.
This document summarizes key information about plant structures and classifications. It begins by identifying the four main characteristics shared by all plants: they perform photosynthesis, have a cuticle layer, cell walls, and alternation of generations. It then describes the four major groups of plants as nonvascular plants, vascular plants, seed plants, and flowering plants. The document provides examples and explains the structures, functions, and importance of roots, stems, leaves, and flowers. It also distinguishes between gymnosperms and angiosperms.
Flowering plants reproduce through seeds contained within fruits. Angiosperms produce fruits containing seeds after pollination. Gymnosperms have small flowers and their seeds develop in cones, including many conifer trees. Non-flowering plants reproduce asexually through spores and include ferns and mosses, with ferns being some of the oldest plant life on Earth evolving over 300 million years ago.

Parts of plants (roots, stem, leaf, flower, fruit, seed) slidesharelilycastle
Plants have several key parts that work together to help them grow and survive. The roots hold the plant in the ground and take in water and nutrients from the soil. The stem carries water and nutrients between the roots and leaves. The leaves take in sunlight to produce food for the plant through photosynthesis and produce seeds or fruit that contain seeds to make new plants.
Basic presentation of the parts of a plant and of the life cycle of plants. Pitched at about the 2nd, 3rd or 4th grade level. Lots of descriptive pictures and diagrams.
Seed plants have three key characteristics: they produce seeds, their sperm do not require water and are transported within pollen grains, and they are the most common plants on Earth. A seed forms after fertilization and contains three parts - the young plant, stored food, and a protective seed coat. Seed plants have advantages over seedless plants as their seeds can be dispersed farther. Gymnosperms and angiosperms are two major groups of seed plants. Gymnosperms produce conifer cones while angiosperms produce flowers and fruits. Both have adaptations that aid reproduction and dispersal.
The document discusses the main parts and functions of plants. It explains that most plants have three main parts: roots, stems, and leaves. The roots hold the plant in the soil and absorb water and minerals. The stem carries water and minerals from the roots to the leaves, supports the plant, and can be thick like a tree trunk, thin like a bush, or soft like grass. The leaves make food for the plant using sunlight, air, and water. Flowers are the reproductive part where seeds form, and fruit protects the seeds so new plants can grow.
Flowering plants first appeared around 135 million years ago and have since diversified greatly. They have flowers that attract pollinators like bees, helping the plants reproduce. There are over 500 ways to classify flowers based on their many variations from crossed genes between species. Angiosperms can be divided into two main classes - monocots and dicots - based on their seeds and seedling structure. Monocots have one seed and dicots have two. Angiosperms can also be classified as woody, herbaceous, annual, perennial, or biennial based on characteristics like their stem structure and lifespan.
The document discusses the parts of plants and trees. It describes that plants have roots, stems, leaves, flowers, and seeds. Trees have additional parts like trunks, branches, and bark. The roots anchor the plant and absorb water and nutrients from the soil. The stem transports water and food throughout the plant and holds up leaves and flowers. Leaves collect sunlight through photosynthesis and release oxygen. Flowers attract insects to aid in pollination and reproduction through seeds or fruits.
The document discusses the main parts of a plant and their functions. It identifies roots as absorbing water and nutrients from the soil, stems as transporting water and nutrients up and down the plant and providing structure, and leaves as using sunlight, water and air to produce food through photosynthesis. Flowers attract insects to aid reproduction, and fruits protect and contain seeds from which new plants can grow.
Plants have four main parts: roots, which absorb water from the soil; stems, which support the plant; leaves, which receive sunlight; and flowers, which are the reproductive parts of plants. The document discusses the four main parts of plants - roots, stems, leaves, and flowers - and their basic functions.
This document discusses the different parts of plants and their functions, as well as the process of photosynthesis. It notes that plants have leaves, stems, roots, and flowers, with each part playing an important role - leaves make food through photosynthesis, stems transport water and nutrients, roots absorb water and nutrients from the soil, and flowers produce seeds. The document then examines the structure and function of leaves in more detail, and classifies plants based on their structure, root and stem types, whether they produce seeds or spores, and whether they are edible.
The document discusses the three main parts of a seed - the seed coat, stored food, and baby plant. It then describes the four main parts of a plant - roots, stem, leaves, and flower. The roots take in water and minerals from the soil. The stem carries water and helps the plant grow tall. The leaves make food for the plant using sunlight, water, and air. The flower makes seeds to form new plants.
Plants have four basic parts - leaves, stems, roots, and flowers. Leaves produce food for the plant through photosynthesis. Stems transport water, minerals, and food throughout the plant. Roots absorb water and minerals from the soil. Flowers lead to reproduction through pollination and formation of fruits and seeds. Plants are vital as they produce oxygen, food, fuel, and build materials and provide habitat for wildlife.
Plants make seeds that can grow into new plants, but if the seeds just fall to the ground under the parent plant, they might not get enough sun, water or nutrients from the soil. Because plants cannot walk around and take their seeds to other places, they have developed other methods to disperse (move) their seeds. The most common methods are wind, water, animals, explosion and fire.
This document summarizes the main plant parts and their functions. It discusses the parts and functions of seeds, roots, leaves, stems, and flowers. Seeds contain an embryo, endosperm, cotyledon, and seed coat. Roots absorb water and nutrients, anchor the plant, and transport materials. Leaves perform photosynthesis and transpiration. The stem transports water and nutrients and supports other plant structures. Flowers are pollinated to produce fruit and seed.
This document provides information about plants in three sections. It first describes what plants need to survive, including water, soil, air, and sunlight. It then explains the plant life cycle of a seed growing into a plant that feeds, reproduces, and eventually dies. Finally, it discusses different types of plants like trees, flowers, fruits, wild plants, and crops as well as why plants are grown.
The document discusses a classroom experiment where students planted sunflower seeds in soil, paper towels, and various containers to observe plant growth over 4 days. The seeds began to sprout stems and leaves, and the students watched as the sunflowers and roots continued to grow with regular watering. They explored how sunflower seeds develop into plants when provided with the necessary requirements of soil, water, sun, and air.
The document discusses the basic requirements for planting flowers, including watering the soil. It explains that seeds come in different sizes, colors, and types, some of which people eat, such as rice, peas, corn, and cucumbers. Examples of seeds shown include sunflowers, pumpkins, and roses. The document also covers the main parts of a plant - roots, stem, leaves, and petals - and provides an interactive exercise to test plant part identification.
This document discusses the characteristics of flowering plants. Flowering plants, or angiosperms, are defined as plants that produce flowers. They are divided into two main classes - monocots and dicots - based on whether they have one or two cotyledons. Flowering plants are distinguished from other seed plants by their production of flowers and fruits. Examples of flowering plants mentioned include roses, lotuses, tulips and marigolds.
Flowering plants reproduce sexually through their flowers. The male reproductive organ is the stamen, which produces pollen containing sperm cells. The female reproductive organ is the pistil, which contains ovules equivalent to the pollen grains. Plants can also reproduce asexually through various vegetative propagation methods like budding, fragmentation, and artificial propagation techniques such as grafting and layering.
This document provides an overview of plant characteristics and classification. It discusses the key parts and processes of seed plants including angiosperms and gymnosperms. Seed plants are classified into gymnosperms, which produce naked seeds, and angiosperms, which produce seeds within fruits. Angiosperms undergo pollination and fertilization to produce seeds which are then dispersed by fruits. This allows for sexual reproduction through cross-pollination and asexual reproduction through vegetative propagation. Seed plants are essential to humans and ecosystems.
Plants have basic needs of temperature, light, water, air, nutrients, and space to grow. They are eukaryotes that can produce their own food through photosynthesis. Plants have two main stages in their life cycle - the sporophyte produces spores and the gametophyte produces sex cells. There are two divisions of plants - vascular plants that have transport tissues and nonvascular plants that do not. Nonvascular plants include mosses, liverworts, and hornworts while vascular plants are divided into spore producers like ferns and seed producers. Seed plants are further divided into gymnosperms like conifers that produce naked seeds and angiosperms that produce seeds in an enclosed ovary.

The poem expresses the speaker's appreciation for trees. It describes various aspects of trees, such as how they drink from the "earliest sweet flowing breast" of water, look at God all day while lifting their leafy arms in prayer, and wear nests of robins in their hair. The final line contrasts trees, which are made by God, with poems, which are made by "fools like me." The poem uses personification and vivid imagery to convey a sense of awe and wonder towards trees.
The document discusses plant reproduction and genetics. It begins by explaining that flowering plants produce sex cells or gametes in the form of ovules and pollen grains within reproductive parts of the plant like the flower. The male reproductive organ is the stamen, which produces pollen containing sperm cells. The female reproductive organ is the pistil, where ovules are produced. Plants can reproduce sexually through cross-fertilization with other plants or self-fertilization. They can also reproduce asexually through various vegetative propagation methods like budding, cutting, grafting, and tissue culture. The document then discusses genetics, explaining what genes and DNA are and their roles in determining traits. It describes DNA structure and how DNA replicates
The document provides information about plants, including common plant names, parts of plants, the life cycle of plants, how plants reproduce, what plants need to grow, plant adaptations, and uses of plants by humans. It includes diagrams labeling parts of plants, images showing the plant life cycle, and descriptions of processes like photosynthesis, pollination, seed dispersal methods, and responses of plants to their environment. It asks questions throughout to check the reader's understanding.
This document provides an overview of plant botany, defining key terms like trees, shrubs, herbs, stems, leaves, flowers, and fruits.

The document discusses plant reproduction and strategies for seed dispersal. It explains that flowers evolved to facilitate sexual reproduction in plants and allow plants to pass their genes to offspring. Various dispersal mechanisms are described, including wind dispersal for seeds with wings or plumes, water dispersal for buoyant seeds, and animal dispersal for seeds contained in fleshy fruits or attached to hooks/barbs. The mistletoe plant is highlighted as having evolved a mutualistic relationship with mistletoebirds, which eat the fruit but disperse intact seeds in their droppings, aiding the plant's dispersal.

Fungi are multicellular organisms that are not closely related to plants or animals. They break down organic matter as decomposers and can also feed on plants and animals. Plants evolved from algae and developed vascular tissue, roots, stems and leaves to adapt to life on land. They reproduce using alternation of generations between haploid gametophytes and diploid sporophytes. Angiosperms are the most abundant group of plants and reproduce using flowers and seeds. Plant tissues include epidermis, ground tissue and vascular tissue which transports water and nutrients.
The plant kingdom is divided into two main groups: vascular and non-vascular plants. Vascular plants have tissues that transport water and nutrients throughout the plant. Non-vascular plants like mosses and liverworts lack these tissues and rely on cell walls for transport. Seedless plants reproduce via spores and include non-vascular bryophytes as well as vascular horsetails, ferns, and spikemosses. Seed plants have true roots, stems, leaves and vascular tissues. They reproduce via seeds and are divided into gymnosperms like conifers, which have naked seeds, and angiosperms, which produce flowers and fruits containing seeds. Angiosperms are further divided into monocots and dicots.
Flowers have different parts that allow plants to reproduce. Sepals protect the bud, petals attract pollinators, and reproductive parts include carpels and stamens. Carpels contain ovaries, styles and stigmas while stamens contain filaments and anthers. Pollination occurs when pollen is transferred, allowing fertilization to take place in the ovary and seeds to develop. Seeds are then dispersed by various methods like wind, water, or animals so new plants can grow in different locations away from the parent plant and not be overcrowded. During germination, seeds need water and warmth to grow into new plants, completing the life cycle of flowering plants.
This document discusses various methods of plant reproduction, including sexual and asexual reproduction. Sexual reproduction in plants involves the transfer of pollen from male to female parts, leading to the production of seeds. Flowers are the main structures involved in sexual reproduction, containing both male stamens and female pistils. Asexual reproduction allows for cloning and involves processes like vegetative reproduction through stems/roots as well as artificial propagation techniques such as cutting, grafting, marcotting, and tissue culture.
Flowers are the reproductive organs of seed-bearing plants. They typically have four parts arranged in concentric rings: pistil, stamens, petals, and sepals. The pistil is located in the center and contains the stigma, style, and ovary where ovules develop into seeds. Surrounding the pistil are the stamens which contain anthers that produce pollen. Outside the stamens are brightly colored petals which attract pollinators. The outermost whorl is made up of sepals which protect the developing flower bud.
The document discusses the key structures and processes of plants, including:
- Plants obtain energy through photosynthesis in their leaves and cellular respiration throughout the plant.
- They have evolved specialized tissues like vascular tissue to transport water and nutrients.
- Reproduction occurs through flowers, fruits, and cones, with angiosperms having seeds in fruits and gymnosperms using cones.
The document discusses the life cycle of a plant from seed to pollination in several stages:
1) A seed starts as a hard coated structure that germinates with sunlight and water, developing into a plant.
2) Roots form and push into the ground while a stem grows upwards, forming leaves to photosynthesize.
3) Flowers are produced to attract pollinators like insects and animals.
4) Pollination occurs when pollen is transferred between flowers by pollinators or wind, allowing seeds to form and the cycle to repeat.
This document summarizes key aspects of plant structure and function. It describes how plants are grouped based on characteristics like whether they are vascular or nonvascular. It explains the main parts of vascular plants - roots, stems, and leaves - and their various structures and functions. The document also details photosynthesis, the process by which plants use sunlight, carbon dioxide, and water to produce oxygen and energy in the form of sugar. It compares how plants, animals, and decomposers obtain energy and survive.

Microbial interaction
Microorganisms interacts with each other and can be physically associated with another organisms in a variety of ways.
One organism can be located on the surface of another organism as an ectobiont or located within another organism as endobiont.
Microbial interaction may be positive such as mutualism, proto-cooperation, commensalism or may be negative such as parasitism, predation or competition
Types of microbial interaction
Positive interaction: mutualism, proto-cooperation, commensalism
Negative interaction: Ammensalism (antagonism), parasitism, predation, competition
I. Mutualism:
It is defined as the relationship in which each organism in interaction gets benefits from association. It is an obligatory relationship in which mutualist and host are metabolically dependent on each other.
Mutualistic relationship is very specific where one member of association cannot be replaced by another species.
Mutualism require close physical contact between interacting organisms.
Relationship of mutualism allows organisms to exist in habitat that could not occupied by either species alone.
Mutualistic relationship between organisms allows them to act as a single organism.
Examples of mutualism:
i. Lichens:
Lichens are excellent example of mutualism.
They are the association of specific fungi and certain genus of algae. In lichen, fungal partner is called mycobiont and algal partner is called
II. Syntrophism:
It is an association in which the growth of one organism either depends on or improved by the substrate provided by another organism.
In syntrophism both organism in association gets benefits.
Compound A
Utilized by population 1
Compound B
Utilized by population 2
Compound C
utilized by both Population 1+2
Products
In this theoretical example of syntrophism, population 1 is able to utilize and metabolize compound A, forming compound B but cannot metabolize beyond compound B without co-operation of population 2. Population 2is unable to utilize compound A but it can metabolize compound B forming compound C. Then both population 1 and 2 are able to carry out metabolic reaction which leads to formation of end product that neither population could produce alone.
Examples of syntrophism:
i. Methanogenic ecosystem in sludge digester
Methane produced by methanogenic bacteria depends upon interspecies hydrogen transfer by other fermentative bacteria.
Anaerobic fermentative bacteria generate CO2 and H2 utilizing carbohydrates which is then utilized by methanogenic bacteria (Methanobacter) to produce methane.
ii. Lactobacillus arobinosus and Enterococcus faecalis:
In the minimal media, Lactobacillus arobinosus and Enterococcus faecalis are able to grow together but not alone.
The synergistic relationship between E. faecalis and L. arobinosus occurs in which E. faecalis require folic acid
Candidate young stellar objects in the S-cluster: Kinematic analysis of a sub...Sérgio Sacani
Context. The observation of several L-band emission sources in the S cluster has led to a rich discussion of their nature. However, a definitive answer to the classification of the dusty objects requires an explanation for the detection of compact Doppler-shifted Brγ emission. The ionized hydrogen in combination with the observation of mid-infrared L-band continuum emission suggests that most of these sources are embedded in a dusty envelope. These embedded sources are part of the S-cluster, and their relationship to the S-stars is still under debate. To date, the question of the origin of these two populations has been vague, although all explanations favor migration processes for the individual cluster members. Aims. This work revisits the S-cluster and its dusty members orbiting the supermassive black hole SgrA* on bound Keplerian orbits from a kinematic perspective. The aim is to explore the Keplerian parameters for patterns that might imply a nonrandom distribution of the sample. Additionally, various analytical aspects are considered to address the nature of the dusty sources. Methods. Based on the photometric analysis, we estimated the individual H−K and K−L colors for the source sample and compared the results to known cluster members. The classification revealed a noticeable contrast between the S-stars and the dusty sources. To fit the flux-density distribution, we utilized the radiative transfer code HYPERION and implemented a young stellar object Class I model. We obtained the position angle from the Keplerian fit results; additionally, we analyzed the distribution of the inclinations and the longitudes of the ascending node. Results. The colors of the dusty sources suggest a stellar nature consistent with the spectral energy distribution in the near and midinfrared domains. Furthermore, the evaporation timescales of dusty and gaseous clumps in the vicinity of SgrA* are much shorter ( 2yr) than the epochs covered by the observations (≈15yr). In addition to the strong evidence for the stellar classification of the D-sources, we also find a clear disk-like pattern following the arrangements of S-stars proposed in the literature. Furthermore, we find a global intrinsic inclination for all dusty sources of 60 ± 20◦, implying a common formation process. Conclusions. The pattern of the dusty sources manifested in the distribution of the position angles, inclinations, and longitudes of the ascending node strongly suggests two different scenarios: the main-sequence stars and the dusty stellar S-cluster sources share a common formation history or migrated with a similar formation channel in the vicinity of SgrA*. Alternatively, the gravitational influence of SgrA* in combination with a massive perturber, such as a putative intermediate mass black hole in the IRS 13 cluster, forces the dusty objects and S-stars to follow a particular orbital arrangement.

The debris of the ‘last major merger’ is dynamically youngSérgio Sacani
The Milky Way’s (MW) inner stellar halo contains an [Fe/H]-rich component with highly eccentric orbits, often referred to as the
‘last major merger.’ Hypotheses for the origin of this component include Gaia-Sausage/Enceladus (GSE), where the progenitor
collided with the MW proto-disc 8–11 Gyr ago, and the Virgo Radial Merger (VRM), where the progenitor collided with the
MW disc within the last 3 Gyr. These two scenarios make different predictions about observable structure in local phase space,
because the morphology of debris depends on how long it has had to phase mix. The recently identified phase-space folds in Gaia
DR3 have positive caustic velocities, making them fundamentally different than the phase-mixed chevrons found in simulations
at late times. Roughly 20 per cent of the stars in the prograde local stellar halo are associated with the observed caustics. Based
on a simple phase-mixing model, the observed number of caustics are consistent with a merger that occurred 1–2 Gyr ago.
We also compare the observed phase-space distribution to FIRE-2 Latte simulations of GSE-like mergers, using a quantitative
measurement of phase mixing (2D causticality). The observed local phase-space distribution best matches the simulated data
1–2 Gyr after collision, and certainly not later than 3 Gyr. This is further evidence that the progenitor of the ‘last major merger’
did not collide with the MW proto-disc at early times, as is thought for the GSE, but instead collided with the MW disc within
the last few Gyr, consistent with the body of work surrounding the VRM.
The cost of acquiring information by natural selectionCarl Bergstrom
This is a short talk that I gave at the Banff International Research Station workshop on Modeling and Theory in Population Biology. The idea is to try to understand how the burden of natural selection relates to the amount of information that selection puts into the genome.
It's based on the first part of this research paper:

Authoring a personal GPT for your research and practice: How we created the Q...Leonel Morgado
Thematic analysis in qualitative research is a time-consuming and systematic task, typically done using teams. Team members must ground their activities on common understandings of the major concepts underlying the thematic analysis, and define criteria for its development. However, conceptual misunderstandings, equivocations, and lack of adherence to criteria are challenges to the quality and speed of this process. Given the distributed and uncertain nature of this process, we wondered if the tasks in thematic analysis could be supported by readily available artificial intelligence chatbots. Our early efforts point to potential benefits: not just saving time in the coding process but better adherence to criteria and grounding, by increasing triangulation between humans and artificial intelligence. This tutorial will provide a description and demonstration of the process we followed, as two academic researchers, to develop a custom ChatGPT to assist with qualitative coding in the thematic data analysis process of immersive learning accounts in a survey of the academic literature: QUAL-E Immersive Learning Thematic Analysis Helper. In the hands-on time, participants will try out QUAL-E and develop their ideas for their own qualitative coding ChatGPT. Participants that have the paid ChatGPT Plus subscription can create a draft of their assistants. The organizers will provide course materials and slide deck that participants will be able to utilize to continue development of their custom GPT. The paid subscription to ChatGPT Plus is not required to participate in this workshop, just for trying out personal GPTs during it.
EWOCS-I: The catalog of X-ray sources in Westerlund 1 from the Extended Weste...Sérgio Sacani
Context. With a mass exceeding several 104 M⊙ and a rich and dense population of massive stars, supermassive young star clusters
represent the most massive star-forming environment that is dominated by the feedback from massive stars and gravitational interactions
among stars.
Aims. In this paper we present the Extended Westerlund 1 and 2 Open Clusters Survey (EWOCS) project, which aims to investigate
the influence of the starburst environment on the formation of stars and planets, and on the evolution of both low and high mass stars.
The primary targets of this project are Westerlund 1 and 2, the closest supermassive star clusters to the Sun.
Methods. The project is based primarily on recent observations conducted with the Chandra and JWST observatories. Specifically,
the Chandra survey of Westerlund 1 consists of 36 new ACIS-I observations, nearly co-pointed, for a total exposure time of 1 Msec.
Additionally, we included 8 archival Chandra/ACIS-S observations. This paper presents the resulting catalog of X-ray sources within
and around Westerlund 1. Sources were detected by combining various existing methods, and photon extraction and source validation
were carried out using the ACIS-Extract software.
Results. The EWOCS X-ray catalog comprises 5963 validated sources out of the 9420 initially provided to ACIS-Extract, reaching a
photon flux threshold of approximately 2 × 10−8 photons cm−2
s
−1
. The X-ray sources exhibit a highly concentrated spatial distribution,
with 1075 sources located within the central 1 arcmin. We have successfully detected X-ray emissions from 126 out of the 166 known
massive stars of the cluster, and we have collected over 71 000 photons from the magnetar CXO J164710.20-455217.

As sunlight enters the leaf, some of its energy is absorbed by tiny packages of chlorophyll called chloroplasts contained in the cells of the leaf. The energy of the sun splits the water, provided by the roots and stems, into simpler chemicals called hydrogen and oxygen. The oxygen (a gas) is released throught he stoma into the air, where it is available to be breated by people nad animals. The hydrogen is combined with carbond dioxide ( a gas taken from the air to form a type of sugar called glucose—the food plants need to live. The glucose is shipped away for storage or is used in other parts of the plant.
