Answer:
Parenchyma cells are distinguished by their thin walls and the fact that they are alive at maturity. To sustain structure, collenchyma cells produce thicker secondary cell walls. Sclerenchyma cells produce tissues like bark and vascular tissue by thickening their walls and dying off as they mature.

Sclerenchyma cells produce tissues like bark and vascular tissue by thickening their walls and dying off as they mature.
What are two functions of parenchyma?
Parenchyma cells are actively metabolizing living cells present throughout the plant body. These cells have thin primary cell walls. Some of the functions of parenchymatous cells in plants are storage, photosynthesis, secretions, etc. The photosynthesizing parenchyma cells are mostly present in green leaves of plants and have green chloroplasts.
Some of the parenchymatous cells also serve to store metabolites such as oil droplets, starch grain, water, salts, etc. The secretion of resins, tannin, hormones, nectar, and other substances is done by specialized parenchymatous cells.
Thus, Parenchyma cells are distinguished by their thin walls and the fact that they are alive at maturity.
