Question

an internal factor controlling transpiration​

Answer 1

Answer:

Explanation

1.The thickness of the cuticle.-thick cuticle hinder transpiration by preventing the evaporation of water

2.leaf surface area.-the larger the surface are of the leaf the higher the rate of transpiration

3.glossy leaf surface.-the glossy leaf surface reflects light away to avoid increasing internal temperatures of the leaf that would lead to transpiration.

Answer 2

$\large{\underline{\mathrm{Transpiration-}}}$

The loss of water from plant leaves is known as transpiration.

$\red{\bold{Types-}}$

Stomatal transpiration.

Cuticular transpiration

Lenticular transpiration
