Collenchyma
These cellular structures can be seen in most of the soft parts of a plant.
These cells are present in leaf veins, petioles and young plants.
They have unspecialised cells.
They have specialised cells.
It comprises of a thin cellular wall.
Collenchyma consists of a thick cellular wall.
The wall of a cell consists of only cellulose.
The cell walls comprise of pectin and hemicellulose.
The parenchyma has intercellular space within cells.
There is no or very little intercellular space available within cells.
Its primary functions are photosynthesis, storage of food particles, and repairing of tissues, etc.
The primary function of collenchyma is providing additional support to withstand forces of nature.
It mainly acts as a storage tissue.
Collenchyma acts primarily as a mechanical tissue.
It is available mostly in the outer and inner portions of a plant.
Its presence gets restricted to epidermal layers of plants.
These cells have vacuoles present in it.
Vacuoles are absent in a collenchyma.
They have a spherical, oval, and rectangular form or have a rod-like shape.
Their shapes are variable and lack a specific form.
The cells have a loose arrangement.
The cells of collenchyma have a compact arrangement.
