Sclerenchyma is a simple permanent tissue in plants. Sclerenchymatous cells are dead at their maturity. Cells do not have protoplast when they completely developed. They have thick secondary cell wall. The secondary cell wall is lignified and very hard. Most of the sclerenchymatous cells show intrusive growth. The present post […]

Collenchyma: Structure, Classification and Functions
Collenchyma is a simple permanent tissue in plants. They are living cells with prominent nucleus and all the cell organelles. Each collenchymatous cell is with a large and prominent vacuole in the centre. The vacuole is filled with many secondary metabolites. Unlike parenchyma, the collenchyma cells possess thick primary cell […]

Characteristics of Meristematic Tissue
What is Meristem? Meristem is a group of plant cells that remain in a continuous state of division. It is a tissue system in plants called meristematic tissue. The term meristem was proposed by Karl Nägeli from a Greek word ‘merizein’ which means ‘to divide’. The meristem composed of rapidly […]
