Question

What is stomatal apparatus? Explain the structure of stomata with a labelled diagram.​

Answer 1

Stomatal apparatus includes :

• Pores
• Guard cells
• Subsidiary cells

Stomata are small pores present in the epidermis of leaves.

They regulate the process of transpiration and gaseous exchange.

The stomatal pore is enclosed between two bean-shaped guard cells.

The inner walls of guard cells are thick, while the outer walls are thin.

The guard cells are surrounded by subsidiary cells.

These are the specialised epidermal cells present around the guard cells.

The pores, the guard cells, and the subsidiary cells together constitute the stomatal apparatus.

Answer 2

HLO MATE HERE IS UR ANSWER.

❤. STOMATAL APPARATUS. ❤

The stomatal opening , guard cells and the surrounding subsidiary cells are together called stomatal apparatus.

❤. STRUCTURE OF STOMATA ❤

⭐. stomata are the openings present in the epidermis of leaves.

⭐. stomata are more on the lower surface and less on the upper surface of dicot leaves.

⭐. stomata are equal number on both the surfaces of monocot leaves.

⭐. Each stomata is composed of bean shaped cells known as guard cells.

⭐. In grasses , the guard cells are thin and inner walls are highly thickned.

⭐. The guard ces possess chloroplasts and regulate the opening and closing of stomata.

⭐. The epidermal cells surrounding the guard cells are known as subsidiary cells.
