Question

Observe the structure of stomata from A to H during transpiration and match appropriately.
1. Stomatal pore
2. Accessory cells
3. Outer thin cell wall
4. Guard cells lose water by exosmosis and stomata close
5. Guard cells (kidney shaped)
6. The guard cells take in water by osmosis as indicated by arrows and stomata open
7. Inner thick cell wall
8. Vacuole

• A. A-1, B-5, C-3, D-7, E-8, F-2, G-4, H-6
• B. A-1, B-6, C-3, D-7, E-8, F-2, G-5, H-4
• C. A-2, B-6, C-3, D-7, E-8, F-1, G-5, H-4
• D. A-2, B-5, C-3, D-7, E-8, F-1, G-4, H-6

Answer 1

The correct option is A A-1, B-5, C-3, D-7, E-8, F-2, G-4, H-6

• Transpiration is the process by which moisture is carried through plants from roots to small pores on the underside of leaves, where it changes to vapour and is released to the atmosphere.
• Water is passively transported into the roots and then into the xylem.
• The forces of cohesion and adhesion cause the water molecules to form a column in the xylem.
• Water moves from the xylem into the mesophyll cells evaporates from their surfaces and leaves the plant by diffusion through the stomata.
• Hence, the structure of stomata from A to H during transpiration and match appropriately.
• So, the correct answer is 'A-1, B-5, C-3, D-7, E-8, F-2, G-4, H-6'.
