Parenchyma:
cells are living with isodiametric.
cell wall is thin.
loosely packed with intercellular spaces.
found in chlorenchyma & aerenchyma.
Provide support to plants and stores food.
Collenchyma:
cells are living elongated.
cell wall is thickened at the corners due to deposition of cell wall.
it is tightly packed with very little intercellular spaces.
It is found in leaf stalks below the epidermis.
it give flexibility which allows easy bending of different parts of plants without breaking.
schlerenchyma:
Cells are dead and the cell wall is thickened due to the presence of lignin.
cells are tightly packed without any intercellular spaces.
It is found in stem around vascular bundles in the veins of leaves and in the hard covering of seeds and nuts. It provide mechanic strength to plants.
