Question

Cuticles and bark of leaves prevent transpiration.

Answer 1

Cuticles:

1. The waxy coat present on both sides of the leaf surface is called the cuticle.
2. Cuticles prevent plants from extreme climates like drought and save water.
3. The transpiration through stomata reduces due to cuticles.

Bark:

1. Bark covers the outer surface of the stems.
2. Barks are formed of dead cells that are hydrophobic and therefore water-proof.
3. Barks prevent lenticular transpiration of the stem.
