Question

The inner side of guard cells is 
(a) rough
(b) straight
(c) concave
(d) convex​

Answer 1

Answer:

c is the correct answer according to me

Answer 2

The inner side of the guard cell is concave in outline.

• Guard cells are kidney-shaped cells surrounding each stoma.
• Gaseous exchange occurs through the pores called stomata in plants.
• Each pore is surrounded by a pair of guard cells.
• The opening and closing of stomata are regulated by these guard cells and is called the stomatal movement.
• Stomata open when the guard cells are turgid(water intake) and close in the case of flaccid guard cells( water is lost).
• Turgor pressure is the actual determinant of the stomatal opening and closing.
• The outer wall of the guard cell is thin and convex in outline.
• The inner wall of the guard cell is thick and concave in outline.
• The cells that surround the guard cells are called subsidiary cells.
