Question

Write the differences between Transpiration and Guttation (structures involved).

Answer 1

Transpiration:

1. Transpiration is a phenomenon involving the loss of water as water vapor from plants to the atmosphere.

Guttation:

1. Guttation is a phenomenon involving the loss of water as droplets from the leaf edges.

Transpiration	Guttation
1. Transpiration is the loss of water in the form of vapor from the aerial parts of the plant.	1. Guttation is the loss of water due to excessive root pressure.
2. Transpiration can occur through stomata, lenticels, or cuticles.	2. It occurs through the permanent pores present on the edges of uninjured leaves called the hydathodes.
3. During transpiration, water is lost as water vapor.	3. During guttation, water is lost in the form of droplets.

Hence, transpiration involves structures like stomata, lenticels, and cuticles while guttation involves hydathodes.
