During the mechanism of opening and closing of stomata , the important factor is
A The protein content of the cell
B The turgid and flaccid state of guard cell
C The starch content of cell
D The presence of chloroplast in cell
Answers
Answer:
B
Explanation:
when water concentration is high in plant cell become turgid the phenomena is called turgidity....
due to this the large central vacule pushes the cell content against cell wall due to turgr pressure
Answer:
B. The turgid and flaccid state of guard cell.
Explanation:
the stomata are surrounded by kidney shaped guard cells. The guard cells have thicker walls on the concave side adjoining the stomatal pore. The outer walls of guard cells are thin and elastic. The thick inner walls also show radial arrangement of cellulose microfibrils. The unevenly thickened walls of guard cells result in the bulging of outer wall towards outside, when guard cells become turgid on absorbing water. The bulging of outer wall towards outer side pulls the inner wall with the help of radial cellulose microfibrils.
