Question

Fill in the blanks with the right words from the bracket.

The greater the thickness of the cuticle, the _________ the transpiration. (lesser/greater)

• A. Lesser
• B. Greater

Answer 1

Transpiration:

1. It is the process of loss of water in the form of water vapor from the surface of aerial parts of the plant.
2. The rate of transpiration is dependent on various environmental and plant factors.

Effect of cuticle on transpiration rate:

1. A cuticle is a waxy and protective covering over the epidermis of the leaf surface.
2. The thickness of the cuticle layer over the leaf surface affects the rate of transpiration.
3. The thicker the cuticle layer, the lower the rate of transpiration and vice versa.

Final answer: The greater the thickness of the cuticle, the lesser the transpiration.
