The important functions of stomata are: (i) Exchange of gases with atmosphere, e.g., entry of carbon dioxide for photosynthesis and of oxygen for respiration. (ii) Transpiration, i.e., loss of water in the form of water vapour.

The differences between cell walls of parenchyma, collenchyma and sclerenchyma are given in following table: Parenchyma: (1) Cell wall is primary. (ii) Cell walls thin and made up of cellulose. Collenchyma:(1) Cell wall is primary. (ii) Cell wall has localised thickening of cellulose. Sclerenchyma:Read more

Collenchyma:(1) Cell wall is primary. (ii) Cell wall has localised thickening of cellulose.
Sclerenchyma: (i) Cell wall is secondary. (ii) Cell wall is very thick obliterating internal cellular space. Cell wall is thickened due to

What is the specific function of the cardiac muscle?
Cardiac muscle is present in the heart. It contracts and relaxes rapidly and continuously with a rhythm, but it never gets fatigued

How are simple tissue different from complex tissue in plants?
A simple tissue is made up of only one type of cells where as complex tissue is made up of different types of cells.
