Question

The diagram given below represents the T.S. of monocot leaf. Identify the parts labelled as $A,B,C$ and $D$, which denote their functions and choose the correct one given below.

• A. A: Motor action, B: Photosynthesis, C: Conduction, D: Transpiration
• B. A: Motor action, B: Condution, C: Photosynthesis, D: Transpiration
• C. A: Transpiration, B: Photosynthesis, C: Conduction, D: Transpiration
• D. A: Transpiration, B: Conduction, C: Photosynthesis, D: Motor action

Answer 1

The correct option is A A: Motor action, B: Photosynthesis, C: Conduction, D: Transpiration

The given diagram shows the structure of a monocot leaf.

A- It is bulliform cells which are present in the upper epidermis which actively participates in motor action.

B- Photosynthesis is carried by loosely packed mesophyll cells.

C- Vascular bundles helps in the conduction of organic materials.

D- Transpiration regulated by the guard cell.

So, the correct answer is option A.
