The parts of a plant and their functions
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.
Parts of the plants and their functions
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.
Class IV Green plants
The document discusses the key parts and functions of leaves. It explains that leaves contain chlorophyll which makes them appear green. Leaves have a blade and veins which transport substances like water and minerals. Stomata on the lower leaf surface allow plants to breathe. Leaves act as the food factory of plants, manufacturing food through photosynthesis using sunlight, water and carbon dioxide. Photosynthesis produces oxygen and sugar as a byproduct, with the sugar transported through the plant. Plants and animals depend on each other, as plants produce oxygen for animals and animals produce carbon dioxide for plants. Food chains demonstrate how each organism depends on others as a source of food.
Life cycle of plants
The life cycle of a plant begins with a seed, which germinates into a seedling. The seedling grows into an adult plant that produces flowers. Flowers have male and female parts that are involved in reproduction and enable the plant to produce seeds. Some plants reproduce via cones instead of flowers. Seeds are dispersed by wind, water, or animals eating fruit and depositing seeds elsewhere, allowing new plants to grow and repeat the cycle.

Life cycle of a plant by 4B
Pollination occurs when bees carry pollen from flower to flower, fertilizing them. Fertilization happens when the pollen and seed meet, causing the flower to die and the fruit to form. Seed dispersal then spreads seeds away from the parent plant via animals, wind, or splitting fruits. Germination begins as seeds receive water, sunlight, and oxygen in soil to grow into plants.
All about plants
Plants are living things that require air, water, soil, and sunlight to survive. They produce their own food through the process of photosynthesis, where leaves absorb sunlight and use it to convert carbon dioxide and water into oxygen and sugars. The main parts of a plant are roots, which take in water and nutrients; stems, which transport water and raise leaves and flowers; leaves, which produce food for the plant; and flowers, which produce seeds. Photosynthesis occurs in leaves and uses chlorophyll to power the process of turning carbon dioxide, water, and sunlight into oxygen and food. Plants are essential as they produce food and oxygen, and help clean the air and soil.
Parts of a flower
The document summarizes the parts of a flower and their roles in reproduction. It explains that flowers contain reproductive organs and are made up of four main parts: sepals, petals, stamens, and pistils. The sepals protect the bud, petals attract pollinators, stamens produce pollen as the male part, and pistils receive pollen and contain ovaries to produce seeds as the female part. Pollination occurs through pollen transfer from the stamen to the pistil by wind, insects, or other animals. Fertilization happens when pollen grains fuse with egg cells in the ovary, developing into seeds and eventually fruit to protect and disperse the seeds.

Open terrariums are used for dry plants like succulents. Desert terrariums contain cacti and desert plants, using sand and stones for decoration. Forest terrariums feature ferns and moss to recreate a woodland environment. The document also provides instructions for building terrariums, including selecting materials, adding drainage layers, soil, plants and decorations.
Reproduction in plants
This document provides information about reproduction in plants. It discusses two main types of reproduction: asexual reproduction, which produces new plants without seeds, including vegetative propagation, budding, spore formation and fragmentation. Sexual reproduction involves the formation of seeds and includes the flower structure with stamen and pistil parts and the pollination process of transferring pollen grains. Seed dispersal is also covered, where seeds are carried from one place to another by various agents.
Seed dispersal
Flowering plants have evolved various adaptations for seed dispersal to spread seeds far from the parent plant. The main methods of seed dispersal are by wind, by animals, by water, and by explosion. Seeds dispersed by wind are light with structures like hairs that aid wind transport. Seeds dispersed by animals pass through digestive tracts unharmed and are deposited far from the parent in feces. Seeds dispersed by water may survive ocean currents, while explosive plant pods forcibly eject seeds from the parent.

Plants are important part of nature. They can live on land and in water. Plants are very useful to us and we get many things from plant such as food, wood, paper etc.
Most of our food that we eat comes from plants for example -fruits, vegetables, cereals, pulses etc. We eat roots, leaves, stems, flowers and fruits of plants.
Types of plants
This document discusses different types of plants. It describes trees as big, strong plants that have trunks and many branches. Herbs are small, weak-stemmed plants that are always green and live for only a few months. Shrubs are small, bushy plants that have hard, woody stems and branches close to the ground. Climber plants have very weak stems and climb trees or walls for support. Creepers have long, weak stems that run along the ground. Thorny plants deter animals from eating them due to their thorns. The document provides examples of different types of plants and activities for students to classify plants.
Uses Of Plant
This document discusses the many uses of plants in daily life. It lists that plants are used as producers in food chains, can produce oxygen through photosynthesis, prevent soil erosion, supply fruits, can be sold for profit, and used to create medicines. Plants play an important role through photosynthesis to produce oxygen and glucose, which supports food chains and webs. They also provide essential fruits to humans while their roots help prevent soil erosion. Overall, the document emphasizes that plants are very helpful to humans and should be planted and respected more.
Plants
Plants are living things that need sunlight, water and air to survive but cannot move because their roots hold them in the ground. Plants make their own food through photosynthesis and come in different forms like trees, shrubs and grass depending on their stem structure. Plants reproduce using seeds which are found inside fruits that grow after flowers appear, and people use different plant parts for food and to make other objects.

Plants
Plants have four main characteristics and are divided into four groups. They are the producers that use photosynthesis to make their own food from sunlight, carbon dioxide, and water. Plants are classified as either nonvascular, which lack transport tissues, or vascular, which have transport tissues to move water and nutrients. Vascular plants are further divided into seedless plants and seed plants. Seed plants form seeds after fertilization which contain a young plant, stored food, and a protective seed coat. They are classified as gymnosperms, which have naked seeds, or angiosperms, which produce flowers and fruits.
PLANTS IN THE SURROUNDINGS - Copy.pptx
Plants provide humans with many essential things like food, clothing, timber, and medicines. They come in many varieties including trees, shrubs, herbs, climbers, and aquatic plants. Plants have two main systems - the root system which absorbs water and minerals from the soil, and the shoot system including stems, leaves, flowers, and fruits. Leaves perform photosynthesis to produce food, while flowers help reproduction and attract pollinators. Fruits contain seeds which germinate into new plants under suitable conditions like moisture, warmth and sunlight. Proper care of plants involves providing them space, water, and avoiding damage.
Plants
Plants are living organisms that have roots, stems, and leaves. Roots draw water and nutrients from the soil up through the stem. Leaves breathe and produce the plant's food through photosynthesis. There are two main groups of flowering plants - gymnosperms which have cones and seeds but no fruit, and angiosperms which have flowers and fruit. Non-flowering plants like mosses and ferns need shade and moisture. All plants undergo respiration and make their own food through photosynthesis using sunlight, carbon dioxide, water, and minerals from the soil.

Morphology and modifications of roots.pptx
The plants that we see today is the result of billions of years of evolution. Today, plants cover almost 30 per cent of the total landmass and account for the 50 per cent of the plant’s productivity (generation of biomass). Plants fulfil many roles in the ecosystem. They are a source of food, nutrition, shelter, maintain the integrity of soil (by preventing erosion) and most importantly, they are the main source for balancing the oxygen level in the atmosphere.

1) Plants are multicellular, eukaryotic organisms that contain cellulose in their cell walls and produce their own food through photosynthesis using chlorophyll.
2) There are four major groups of plants - bryophytes, seedless vascular plants, gymnosperms, and angiosperms - which are separated based on their vascular tissue, seeds, and flowers.
3) Angiosperms are the most common and successful group, as they bear seeds within protective flowers and fruits, allowing for pollination and wide dispersal.
Root morpology ppt
Roots have several important functions for plants. They anchor the plant, absorb water and minerals from the soil to transport throughout the plant. Some roots also store food, such as carrots, radishes and beets. There are two main types of roots: taproots, which are thick primary roots that grow straight down, and fibrous roots, which have many similar roots growing from the stem. Roots can also be modified, such as tuberous roots that store food or nodulated roots with nitrogen-fixing bacteria. Adventitious roots grow from other parts of the plant and take various forms like subterranean, stilt, prop or aerial roots. Roots are important for plant survival and have uses for humans as

It discusses how vascular plants have translocation systems made of phloem and xylem tubes that transport food and water. The key systems in vascular plants are also summarized, including roots that absorb water and nutrients, stems that support the plant and transport fluids, leaves that perform photosynthesis, and flowers, fruits, and seeds that reproduce the plant. Different types of fruits, seeds, and methods of seed dispersal are also outlined.
Plants classification
This document summarizes plant classification and the life cycle of flowering plants. It discusses that plants are classified into non-flowering plants, which reproduce with spores, and flowering plants, which reproduce with flowers and seeds. Flowering plants are further divided into gymnosperms, which have cones and seeds but no fruit, and angiosperms, which produce fruits containing seeds. The document then outlines the process of photosynthesis, pollination leading to fertilization and seed production, and how seeds germinate into new plants. It concludes with describing asexual reproduction methods of tubers, bulbs, and stolons.
Plant of
Roots absorb water and minerals from the soil, anchor the plant, and store food. Stems support the plant, transport water, nutrients, and food between parts, and can be soft or woody. Leaves capture sunlight to produce food for the plant through photosynthesis. Flowers contain pollen and ovules that develop into fruits housing seeds for new plants after pollination and fertilization.
Plant kingdom.pptrb[1]
1) Plants are multicellular, eukaryotic organisms that contain cellulose in their cell walls and produce their own food through photosynthesis using chlorophyll.
2) There are four major groups of plants - bryophytes, seedless vascular plants, gymnosperms, and angiosperms - which are separated based on their vascular tissue, seeds, and flowers.
3) Angiosperms are the most common and successful group, as their flowers attract animals to help with pollination and their seeds develop protected inside the flower.

Plants
- 2. • Plants are living things. • They begin life, grow and die. • They make their own food. • They reproduce. • They are sensitive to light.
- 3. All plants have roots, a stem and leaves. The roots of a plant grow underground. They hold the plant in the ground. A plant receives water and minerals through its roots. The stem of a plant grows above ground. Some stems are hard. Other stems are soft. – Trees and shrubs have hard, wood stems called trunks. These stems have branches. – Grasses have soft, flexible stems. Leaves grow from stems or branches. Many leaves are green, There are different types of leaves.
- 4. WIDE-FLAT POINTED LEAF LOBED LEAF
- 6. NUTRITION IN PLANTS • Plants make their own food in their leaves. This process is called PHOTOSYNTHESIS. • They use water and minerals from the soil. They need air and sunlight. PLANTS MAKE FOOD IN THEIR LEAVES FROM WATER AND MINERALS. THEY USE SUNLIGHT AND SUBSTANCES IN THE AIR. ROOTS ABSORB WATER AND MINERALS FROM THE SOIL. THE WATER AND MINERALS GO TO THE STEM , AND THEN TO THE LEAVES.
- 7. THE PARTS OF A FLOWER Many plants have flowers. Flowers contain the plant’s organ reproduction. The calyx is a group of small green leaves called sepals. It protects the flower. The corolla is a group of coloured petals. The stamens are the male reproductive organs The stamens make pollen. The pistil is the female reproductive organ. It has ovules inside.
- 9. HOW PLANTS REPRODUCE Pollen enters the pistil, and the flower changes. Its petals fall. The pistil becomes a fruit. It has seeds inside. The fruit falls to the ground. Its seeds grow into a new plant in the soil. Some plants, like potatoes, can grow from cuttings. These are parts of the stem or root.
