parenchyma:

parenchyma is a type of simple permanent tissue that makes a major part of ground tissues in plants, where other tissues like vascular tissues are embedded.

They are non-vascular and composed of simple, living and undifferentiated cells, which are modified to perform various functions.

Collenchyma:

These are elongated living cells with small intercellular spaces. Their cell walls are made up of cellulose and pectin.

Collenchyma occur in the peripheral regions of stems and leaves to provide mechanical support and flexibility in plants.

Sclerenchyma:

Sclerenchyma cells are dead cells and they are devoid of protoplasm. They are long and narrow as the walls are thickened due to lignin, such cell walls are called lignified.

The cells of sclerenchyma are closely packed without intercellular spaces.
