AP BIOLOGY

Detailed explanation-1: -They perform various functions such as Photosynthesis, secretion, and storage. Parenchyma cells store food material in the form of oil, fats, proteins, and starch, for example, parenchymatous tissues in roots and stem tubers. So, parenchyma is a simple permanent tissue that helps in storing food in plants.

Detailed explanation-2: -Parenchyma forms the bulk of plant ground tissue, where they may be specialised to function in photosynthesis, storage, or transport. Parenchyma is integral to vascular tissue, where it provides a route of exchange for materials within and between the xylem and the phloem.

Detailed explanation-3: -Xylem parenchyma is the living tissue. It is responsible for the food storage. It is made up of small thin or thick walled parenchymatous cells.

Detailed explanation-4: -Parenchyma cells perform storage (starch and oils) or secretory functions (resins and gums) and form the wood rays that are radially aligned tissues interspersed between the axial elements.

Detailed explanation-5: -These parenchyma cells, called chlorenchyma cells, contain chloroplasts.
