5.) Xylem is the specialised tissue of vascular plants that transports water and nutrients from the plant–soil interface to stems and leaves, and provides mechanical support and storage.
6.)Most photosynthesis takes place in the palisade mesophyll, which is conveniently located at the top of the leaf just under the epidermis.
Spongy mesophyll cells are not packed so tightly together, which allows carbon dioxide and oxygen to reach the palisade cells where they are needed in photosynthesis.
7.)Spongy mesophyll tissue is packed loosely for efficient gas exchange. The spongy mesophyll cells are covered by a thin layer of water. Gases dissolve in this water as they move into and out of the cells.
When the plant is photosynthesising during the day, these features allow carbon dioxide to diffuse into the spongy mesophyll cells, and oxygen to diffuse out of them.
8.)The structure and arrangement of palisade cells in the mesophyll tissue plays a crucial role in photosynthesis. Because of their shape (elongated and cylindrical) palisade cells contain many chloroplasts Palisade cells contain 70 percent of all chloroplasts.
Light absorption happens in the palisade mesophyll tissue of the leaf. Palisade cells are column shaped and packed with many chloroplasts. They are arranged closely together so that a lot of light energy can be absorbed.
9.)Each pair of guard cells and the regulated pore they enclose, known as a stoma or stomate, provides a conduit for atmospheric photosynthetic gas exchange (CO2 uptake and O2 release) and transpirational release of water (H2O) in terrestrial plants, in addition to defense against pathogenic invasion.
10.)The two main functions of stomata are to allow for the uptake of carbon dioxide and to limit the loss of water due to evaporation. In many plants, stomata remain open during the day and closed at night. Stomata are open during the day because this is when photosynthesis typically occurs.
