Detailed explanation-1: -Parenchyma cells are essential for activities like photosynthesis, storage, secretion, assimilation, respiration, excretion and radial transport of water and solute.

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: -The main function of parenchyma is to store and assimilate food. Hence, they are referred to as food storage tissues. Serves as a packing tissue to fill the spaces between other tissues and maintain the shape and firmness of the plant.

Detailed explanation-4: -Parenchyma makes up the chloroplast-laden mesophyll (internal layers) of leaves and the cortex (outer layers) and pith (innermost layers) of stems and roots; it also forms the soft tissues of fruits.

Detailed explanation-5: -They are of two types-phloem parenchyma and xylem parenchyma. Phloem parenchyma consists of cylindrical, elongated, and tapering cells with dense cytoplasm. Xylem parenchyma has thin walls of cellulose. This parenchyma acts as the reservoir of water and food of the cell.
