Question

Discuss the mechanism of stomatal opening in dicot plants.

Answer 1

Answer:

the opening and closing of stomata operate as a result of Turgidity changes in the guard cells. During daytime, guard cells photosynthesis due to which osmotic pressure increases. The guard cells absorb water from the neighboring cells.

Explanation:

Answer 2

• The mechanism of stomatal opening in dicot plants occurs in the leaves.

•stomatal opening and closing is a movement mechanism.

• photosynthesis takes place only in day time.

• During day time stomata are opened for gas exchange, it leads to water loss and plants get drained due to transportation.

• This mechanism will result in a Turgidity change in the guard cells.

• osmotic pressure increases in the guard cells then they will absorb water from neighboring cells.

• They will become turgid. When outer wall cells pushed out and inner walls pulled inwards.

• This will result in stomatal opening.
