Transport in Plants and Animals:Transport of nutrients and other substances across the membrane of a plant and animal's cell takes place through various means such as osmosis, diffusion, and active transport. Transported substances either move from a region of high concentration to a region of ...
Why xylem transport is unidirectional and phloem transport bi-directional. 0Ans Explain pressure flow hypothesis of translocation of sugars in plants. 0Ans Describe transpiration pull model of water transport in plants. What are the factors influencing transpiration? How is it useful to plants?
Data collected from more than 2,000 taxa provide an unparalleled opportunity to quantify how extreme wildfires affect biodiversity, revealing that the largest effects on plants and animals were in areas with frequent or recent past fires and within extensively burnt areas. ...
In plants, water transport inside and outside the plant cells is essential in keeping them upright. Plants tend to look wilted when it is not watered for quite some time because the amount of water that is lost is higher than the amount of water that is absorbed. Plant cells primarily use...
Active transport is essential in multifarious biological processes. It is employed in many biochemical pathways (e.g. proton gradient generation in chloroplasts and chemosynthesis in mitochondria). In plants, ABC transporter PhABCG1 is responsible for the active transport of volatile organic compounds ...
2.13Understand that movement of substances into and out of cells can be by diffusion, osmosis and active transport -Video 2.14Understand the importance in plants of turgid cells as a means of support -Video 2.15Understand the factors that affect the rate of movement of substances into and out ...
Understanding plant function is the key to enhancing crop production, preserving plant biodiversity, producing medicines, and much more. However, in order to understand plant function, one must understand plant form. General Anatomical Organization of Plants Like animals, plant bodies are made up of...
In wildlife tagging, stress from capture and handling can alter post- release behavior and potentially study interpretations. This study of 42 mammal species shows that these effects diminish within 4–7 days, and quicker for animals in high human activity areas indicating adaptation to disturbance...
All other plants, including the ferns, gymnosperms, and angiosperms, are classified as tracheophytes. These possess specialized vascular tissues— phloem and xylem —to transport sugars, water, and minerals throughout their bodies. The oldest known vascular plants appeared in the middle Silurian perio...
UNIT 2: Structural Organisation in Animals and Plants Morphology and Modifications: Tissues; Anatomy and functions of different parts of flowering plants: Root, stem, leaf, inflorescence- cymose and recemose, flower, fruit and seed (To be dealt along with the relevant practical of the Practical ...
