Question

Differentiate between the transpiration and guttation on the basis of structures involved.

Answer 1

1. A process by which water is lost in form of water vapor from the aerial parts of the plants is called transpiration.
2. Guttation is the process of secretion of water droplets from the pores of some vascular plants like grass.

Differences between the transpiration and guttation are:

Transpiration		Guttation
1.	Transpiration occurs through the stomata of leaves.	1.	Guttation takes place through the hydathodes.
2.	Stomata are the tiny openings present on the surface of the leaf through which gaseous exchange and transpiration occur.	2.	A hydathode is a form of pore that emits water through epidermal pores or leaf borders, generally near the tip of a peripheral tooth or serration, and is commonly found in angiosperms.
