Assuming the stomata are open to the same degree, the rate of transpiration should _____ on a rainy day compared with a sunny da
Allushta [10]

Answer:

decline: decrease

Explanation:

Transpiration is the loss of water from stomata by the process of evaporation. It occurs by the process of diffusion and is driven by the concentration gradient of water vapor. The higher the concentration gradient between air and leaf cells, the higher is the rate of diffusion of water.

On a sunny day, the rate of transpiration is higher since air is less humid and the concentration of water inside the leaf is higher. On the other hand, the air is more humid on a rainy day. The increased water vapor content of air reduces the concentration gradient between air and leaf cells. The reduced concentration gradient decreases the rate of transpiration.
