Tissues
There are four main types of tissues in plants and animals:
1. Meristematic tissue, found at growing tips of stems and roots, is composed of actively dividing cells responsible for growth.
2. Permanent tissues have differentiated cells that perform specific functions and do not divide. These include simple tissues like parenchyma and complex tissues like xylem and phloem.
3. The four main animal tissues are epithelial, connective, muscle and nervous tissue. Epithelial tissue lines surfaces, connective tissue connects and supports, muscular tissue enables movement, and nervous tissue conducts electrical signals.
Transport in plants 2018
There are two transport systems in plants - xylem and phloem. Xylem vessels transport water and minerals from the roots upward through the plant. Phloem vessels transport sugars and amino acids made in the leaves throughout the plant. Transpiration is the loss of water vapor from the leaves through stomata and affects the rate of water uptake, increasing with temperature, wind speed, and light intensity but decreasing with humidity. Adaptations of plants to dry conditions include reduced leaves, swollen stems, waxy cuticles, deep roots, and sunken or hairy stomata.
Plant tissues
Plant tissues are classified into two main types: meristematic and permanent tissues. Meristematic tissues are responsible for cell production and are found at growing tips, while permanent tissues provide structure and transport functions. The four main permanent tissues are surface tissues, fundamental tissues of parenchyma, collenchyma and sclerenchyma, and vascular tissues of xylem and phloem which transport water, minerals and food respectively.
Cell Organelles Power Point
Cell organelles have specialized functions within cells. The nucleus contains DNA and controls the cell, the endoplasmic reticulum transports proteins and detoxifies toxins, and mitochondria produce energy through respiration. Other organelles like chloroplasts, lysosomes, vacuoles, and the cell membrane have important roles in photosynthesis, digestion, storage, and boundary definition.
Summary of cell structures
The document lists the key structures found in plant and animal cells and provides a brief description of their structure and function. It identifies that plant cells contain cell walls, chloroplasts, and usually one large central vacuole, while animal cells contain centrioles, lysosomes, and typically a few small vacuoles. Many structures, such as the cytoskeleton, endoplasmic reticulum, Golgi apparatus, mitochondria, nucleus, plasma membrane, and ribosomes are common to both plant and animal cells.

Xylem transports water and minerals up from the roots while phloem transports sugar and nutrients throughout the plant. The document contains diagrams labeling these tissues in stems and leaves of dicotyledonous plants.
Vacuole
The vacuole is a membrane-bound organelle that stores materials like water, nutrients, and waste products inside plant and animal cells. It provides structure for plant cells when full of fluid and maintains the cell's pH by storing unwanted materials. The vacuole would ally with chloroplasts to provide them with water for photosynthesis and is more important to the cell than lysosomes, which break down materials but are not solely responsible for digestion.
The transport of substances in plants
This document discusses transport processes in plants. It describes how:
1) Xylem vessels, tracheids and sieve tubes transport water and minerals from roots to leaves, while phloem transports organic substances like sugars from leaves to storage organs.
2) Translocation refers to the transport of dissolved organic solutes in the phloem from leaves (source) to roots and storage organs (sinks).
3) Transpiration is the loss of water vapor from leaves and involves the opening and closing of stomata to regulate water loss while allowing for gas exchange. Various environmental factors like light, temperature and humidity affect transpiration rate.
4) Water moves through the plant via root pressure,
Tracheid and vessel elements
This document compares and contrasts tracheids and vessel elements, which are both elongated, dead cells that form the xylem tissue.

The document discusses specialized tissues in plants. It begins by explaining that plants are complex living organisms with cells and tissues that work together effectively. It then describes the three principal organs of seed plants - roots, stems, and leaves. It details the main tissue systems (dermal, vascular, and ground tissue) and cell types found in plants, and their functions in structure, transport, photosynthesis, and other processes. It concludes by discussing meristems, regions of undifferentiated cells that produce new cells and allow plants to grow.
Tissues
In plant anatomy, tissues are categorized broadly into three tissue systems: the epidermis, the ground tissue, and the vascular tissue. Epidermis - Cells forming the outer surface of the leaves and of the young plant body. Vascular tissue - The primary components of vascular tissue are the xylem and phloem.

The document discusses the three main types of plant cells - parenchyma, collenchyma, and sclerenchyma. It then describes the four main types of plant tissue - dermal, vascular, ground, and meristematic tissue. Specifically, it outlines the structure and function of parenchyma cells, collenchyma cells, sclerenchyma cells, the epidermis, stomata, xylem, phloem, and companion cells.
"Tissues" Chapter:-6 Class 9
1) Tissues are groups of cells that work together to perform specific functions. In plants and animals, tissues are organized into organs and organ systems.
2) Plant tissues are divided into meristematic tissues, which facilitate growth, and permanent tissues, which carry out other functions. Permanent tissues include simple tissues like parenchyma, collenchyma and sclerenchyma, and complex tissues like xylem and phloem that transport water and nutrients.
3) Animal tissues include four main types - epithelial tissues, muscular tissues, connective tissues and nervous tissues. Epithelial tissues cover and line body surfaces, muscular tissues enable movement, connective tissues connect and support other tissues, and

This document provides information about tissues in multi-cellular organisms. It explains that in multi-cellular organisms, cells specialize to perform specific functions. Groups of specialized cells that perform a particular function together are called tissues. The document discusses the main types of plant tissues, including meristematic tissue, permanent tissues like parenchyma and sclerenchyma, and complex tissues like xylem and phloem. It also discusses the four main types of animal tissues - epithelial, connective, muscular and nervous tissues - and provides examples to illustrate each tissue type.
Vascular Tissue
Vascular tissue consists of xylem and phloem and evolved to transport water and nutrients in land plants. Xylem is composed of tracheids and vessel elements that form tubes to transport water and minerals from roots to leaves. Phloem is made of sieve tube cells and companion cells that transport sugar and nutrients in the opposite direction from leaves to other plant parts. Together, xylem and phloem allow for circulation of water, minerals and organic compounds throughout the plant.
Transport in flowering plants
The document is a PowerPoint presentation for a grade 9 biology class on transport in flowering plants. It summarizes that plants have two transport systems: xylem and phloem. Xylem vessels carry water and minerals from the roots to the leaves, while phloem tubes carry manufactured food from the leaves to other plant parts. Key structures like root hairs, vascular bundles and stomata are also explained in their role in plant transport.
Plant tissues
A plant tissue is a cell or a group of cells that give rise to large number of cell, which is collectively called tissues.

Amoebas respire through their cell membranes, earthworms through skin with many blood vessels, cockroaches through a tracheal network, scorpions through book lungs, fish through gills, frogs through skin, mouth and lungs, and tadpoles through gills as larvae. The complexity of respiratory organs increases with organism complexity, while cellular respiration remains similar.
physical science
This document introduces Anju J.S., a student at Victory College of Teacher Education studying physical science. It summarizes Newton's Three Laws of Motion, including examples for each law. Newton's First Law states that an object at rest stays at rest or an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. Newton's Second Law states that the acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the direction of the net force. Newton's Third Law states that for every action, there is an equal and opposite reaction.
Biology
Animal tissues are groups of cells that have similar structures and functions and combine to form organs. There are four main types of animal tissues: epithelial tissue, connective tissue, muscle tissue, and nervous tissue. Epithelial tissue forms linings and protects internal parts of the body. Connective tissues include structures like blood, bone, and cartilage that provide binding and support. Muscle tissues contain muscle cells and allow for movement. Nervous tissue is made of neurons and coordinates organs by generating electrical signals transmitted through the brain, spinal cord, and nerves. In animals, organs are composed of various combinations of these four basic tissue types to perform specialized functions.

There are different types of plant tissues that are formed from meristematic cells including parenchyma, collenchyma, sclerenchyma, xylem and phloem. Parenchyma tissue is composed of cells with the simplest structure and is found in soft plant parts where it helps with photosynthesis and food storage. Collenchyma tissue provides flexibility and support, with cells thickened at the corners. Sclerenchyma tissue has uniformly thickened cells and provides strength. Xylem and phloem are vascular tissues; xylem transports water and minerals from roots to leaves while phloem transports food from leaves to other plant parts.

There are four main types of animal tissues: epithelial tissue, connective tissue, muscle tissue, and nervous tissue. Each tissue has a distinct structure and function. Epithelial tissue forms linings and covers surfaces, and can be secretory. Connective tissues include structures like blood, bone, and cartilage that support and bind other tissues. Muscle tissues contain muscle cells and provide movement. Nervous tissue is composed of neurons and coordinates the body's organs through signal transmission. Together these four tissue types form the basic building blocks that compose animal organs through various combinations tailored to function.

Unlocking the mysteries of reproduction: Exploring fecundity and gonadosomati...
The pygmy halfbeak Dermogenys colletei, is known for its viviparous nature, this presents an intriguing case of relatively low fecundity, raising questions about potential compensatory reproductive strategies employed by this species. Our study delves into the examination of fecundity and the Gonadosomatic Index (GSI) in the Pygmy Halfbeak, D. colletei (Meisner, 2001), an intriguing viviparous fish indigenous to Sarawak, Borneo. We hypothesize that the Pygmy halfbeak, D. colletei, may exhibit unique reproductive adaptations to offset its low fecundity, thus enhancing its survival and fitness. To address this, we conducted a comprehensive study utilizing 28 mature female specimens of D. colletei, carefully measuring fecundity and GSI to shed light on the reproductive adaptations of this species. Our findings reveal that D. colletei indeed exhibits low fecundity, with a mean of 16.76 ± 2.01, and a mean GSI of 12.83 ± 1.27, providing crucial insights into the reproductive mechanisms at play in this species. These results underscore the existence of unique reproductive strategies in D. colletei, enabling its adaptation and persistence in Borneo's diverse aquatic ecosystems, and call for further ecological research to elucidate these mechanisms. This study lends to a better understanding of viviparous fish in Borneo and contributes to the broader field of aquatic ecology, enhancing our knowledge of species adaptations to unique ecological challenges.

The use of Nauplii and metanauplii artemia in aquaculture (brine shrimp).pptx
Although Artemia has been known to man for centuries, its use as a food for the culture of larval organisms apparently began only in the 1930s, when several investigators found that it made an excellent food for newly hatched fish larvae (Litvinenko et al., 2023). As aquaculture developed in the 1960s and ‘70s, the use of Artemia also became more widespread, due both to its convenience and to its nutritional value for larval organisms (Arenas-Pardo et al., 2024). The fact that Artemia dormant cysts can be stored for long periods in cans, and then used as an off-the-shelf food requiring only 24 h of incubation makes them the most convenient, least labor-intensive, live food available for aquaculture (Sorgeloos & Roubach, 2021). The nutritional value of Artemia, especially for marine organisms, is not constant, but varies both geographically and temporally. During the last decade, however, both the causes of Artemia nutritional variability and methods to improve poorquality Artemia have been identified (Loufi et al., 2024).
Brine shrimp (Artemia spp.) are used in marine aquaculture worldwide. Annually, more than 2,000 metric tons of dry cysts are used for cultivation of fish, crustacean, and shellfish larva. Brine shrimp are important to aquaculture because newly hatched brine shrimp nauplii (larvae) provide a food source for many fish fry (Mozanzadeh et al., 2021). Culture and harvesting of brine shrimp eggs represents another aspect of the aquaculture industry. Nauplii and metanauplii of Artemia, commonly known as brine shrimp, play a crucial role in aquaculture due to their nutritional value and suitability as live feed for many aquatic species, particularly in larval stages (Sorgeloos & Roubach, 2021).
Applied Science: Thermodynamics, Laws & Methodology.pdf
When I was asked to give a companion lecture in support of ‘The Philosophy of Science’ (https://shorturl.at/4pUXz) I decided not to walk through the detail of the many methodologies in order of use. Instead, I chose to employ a long standing, and ongoing, scientific development as an exemplar. And so, I chose the ever evolving story of Thermodynamics as a scientific investigation at its best.
Conducted over a period of >200 years, Thermodynamics R&D, and application, benefitted from the highest levels of professionalism, collaboration, and technical thoroughness. New layers of application, methodology, and practice were made possible by the progressive advance of technology. In turn, this has seen measurement and modelling accuracy continually improved at a micro and macro level.
Perhaps most importantly, Thermodynamics rapidly became a primary tool in the advance of applied science/engineering/technology, spanning micro-tech, to aerospace and cosmology. I can think of no better a story to illustrate the breadth of scientific methodologies and applications at their best.
Deep Software Variability and Frictionless Reproducibility
Deep Software Variability and Frictionless ReproducibilityUniversity of Rennes, INSA Rennes, Inria/IRISA, CNRS
The ability to recreate computational results with minimal effort and actionable metrics provides a solid foundation for scientific research and software development. When people can replicate an analysis at the touch of a button using open-source software, open data, and methods to assess and compare proposals, it significantly eases verification of results, engagement with a diverse range of contributors, and progress. However, we have yet to fully achieve this; there are still many sociotechnical frictions.
Inspired by David Donoho's vision, this talk aims to revisit the three crucial pillars of frictionless reproducibility (data sharing, code sharing, and competitive challenges) with the perspective of deep software variability.
Our observation is that multiple layers — hardware, operating systems, third-party libraries, software versions, input data, compile-time options, and parameters — are subject to variability that exacerbates frictions but is also essential for achieving robust, generalizable results and fostering innovation. I will first review the literature, providing evidence of how the complex variability interactions across these layers affect qualitative and quantitative software properties, thereby complicating the reproduction and replication of scientific studies in various fields.
I will then present some software engineering and AI techniques that can support the strategic exploration of variability spaces. These include the use of abstractions and models (e.g., feature models), sampling strategies (e.g., uniform, random), cost-effective measurements (e.g., incremental build of software configurations), and dimensionality reduction methods (e.g., transfer learning, feature selection, software debloating).
I will finally argue that deep variability is both the problem and solution of frictionless reproducibility, calling the software science community to develop new methods and tools to manage variability and foster reproducibility in software systems.
