Compare parenchyma,chlorenchyma and collenchyma
Answers
Parenchyma is the bulk of a substance. In animals, a parenchyma comprises the functional parts of an organ and in plants parenchyma is the ground tissue of nonwoody structures and have maximum intercellular spaces.
Collenchyma cells are elongated cells with irregularly thick cell walls that provide support and structure. Their thick cell walls are composed of the compounds cellulose and pectin at the corners. These cells are often found under the epidermis, or the outer layer of cells in young stems and in leaf veins.
Sclerenchyma is the supporting tissue in plants. Two types of sclerenchyma cells exist: fibers and sclereids. Their cell walls consist of cellulose, hemicellulose and lignin. Sclerenchyma cells are the principal supporting cells in plant tissues that have ceased elongation.

There are different types of shapes of all the cells, but generally, parenchyma cells are isodiametric, while collenchyma are elongated and sclerenchyma are sclereids, fibre in their shapes respectively. Parenchyma has a thin cell wall of their cells, and are made up of cellulose.

Meaning
The living plant cells are originating from ground and protoderm meristem. These type of cells are most abundantly found in plants tissue. The type of living plant cells originating from the pro-cambium. The epidermal layers of the plant are made of collenchyma cell

The hard and outer part of the stem is made up of the sclerenchyma cells. These are the dead plant cells which originate from ground meristem and protoderm procambium.
