Question

which light cause opening of stomata

Answer 1

hi dear here is the answer

Answer 2

The visible light rays of the Sun causes the opening of the stomata

            Mechanism of opening of stomata

• As soon as the plant undergoes photosynthesis ATP molecules are produced

• These ATP molecules are responsible for the active transport of Potassium(K+) ions from the adjacent cells of the guard cells

• This helps in osmosis . Water enters in the guard cell ( which became hypertonic ) and makes the guard cell turgid

• This leads to opening of stomata.

Hope it helps you:-)
