Detailed explanation-1: -Parenchyma cells are relatively unspecified and thin-walled. It is a group of functional substances present in the animal organs and is structured as a tumor. It is a functional part of an organ and in contrast to the stroma, it refers to the structural tissue of organs which are the connective tissues.

Detailed explanation-2: -They are made up of thin cell wall made up of cellulose, hemicellulose. Plasmodesmata join the cells of the parenchyma tissue. They have several small vacuoles. Their main functions include photosynthesis, storage, secretion, assimilation, respiration, excretion and radial transport of water and solute.

Detailed explanation-3: -Parenchyma cells are living cells, and may still be able to divide when they are mature. Because of this, parenchyma cells are important for regeneration and wound healing. They have thin but flexible cell walls because the secondary cell wall is usually absent.

Detailed explanation-4: -Parenchyma cells are notable for their thin walls, and for being alive at maturity. Collenchyma cells tend to develop thicker secondary cell walls, to support structure. Sclerenchyma cells get both thicker walls and die off at maturity, producing tissues like bark and vascular tissue.

Detailed explanation-5: -They are made up of thin cell wall made up of cellulose, hemicellulose. The cells of parenchyma are isodiametric or polyhedral in shape.
