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 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-3: -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-4: -The unifying characteristic of all parenchyma cells is that they are living at maturity and capable of cell division, giving them important roles in regeneration and wound healing. Other key functions of these cells include photosynthesis, storage, secretion and transport.

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