Parenchyma: thin-walled, polyhedral cells with living protoplasm,
metabolically most active.
Collenchyma: Cell wall is made up of thin and thick portions with
thickening in the corners. Found below the epidermis (stem skin).
Sclerenchyma: highly thickened cell walls. So it is the primary
strengthening tissue found in mature plants. No living protoplasm, some of
these are highly elongated called fibres.
