parenchyma,isdividedinto chlorenchyma,aerenchyma.collenchymais have thick walled, longer cells.sclerenchyma have tightly packed, thick walled cells present.

Generally cells of parenchyma are involved in storage of starch, sucrose, protein, water, phenol derivatives, many mineral substances, etc.  Other metabolisms like respiration, protein synthesis etc., are active.  Parenchymatous cells may also perform specialized functions and are structurally modified.  The following are the different types of parenchyma.

 



  Intercellular spaces filled with air, are large in size and many in number.  Cells occupy a smaller area.  Though the cells are smaller, they provide the required strength to the aquatic plants.  In these plants air spaces are common, helping in aeration and buoyancy.  Air spaces are also seen in roots of grasses, petioles of canna, aroids etc.

 

Cells of photosynthetic parenchyma contain numerous chloroplasts.  These cells are commonly seen in leaves, some times in young shoots.  Cells of Chlorenchyma are of two types –

 

1)   Palisade cells that is elongated and compactly arranged.

2)  Spongy cells that are spaciously arranged and irregularly shaped.

 

Prosenchyma (Pros-to): Cells are elongated, have thick walls and serve as a supporting tissue.  Example: Endosperm cells of seeds.
  Cells are stellate in shape with inward projections of cell wall as arms.  Example: Pinus leaf Mesophy

Collenchyma is a simple, living tissue.  Cell walls are thickened due to deposition of pectin. Collenchyma is the primary supporting tissue in stems, leaves and floral parts of dicots, where as in stems and leaves of monocots collenchyma is usually absent, (instead, sclerenchyma is present in monocots). 


I hope it helps you
