The two primary jobs of parenchyma cells are food storage and transport.
<u>Parenchyma cells-</u>
Parenchyma cells are cells that are living. These cells also have really thin-walls and a structure that is unspecialized. These cells can therefore perform a variety of functions. Parenchyma cells are present throughout a plant. These are present in the form of tissues which are homogenous. Parenchyma cells are present in both the stem and roots. This is the primary reason these cells are involved with the assimilation of nutrients and food. These cells are also present in the flesh of fruits and in seeds, and in the mesophyll of leaves which is why these cells can store food.
A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another. ... Food webs consist of many interconnected food chains and are more realistic representation of consumption relationships in ecosystems.
