By looking at a plant externally can you tell whether a plant is C3 or C4? Why and how? | NCERT solution | Class 11 Biology | Unit-13 Photosynthesis in Higher Plants



Q.1:- By looking at a plant externally can you tell whether a plant is C3 or C4? Why and how?

 

Answer:- 



Plants which are adapted to dry climates follow the C4 pathway. While this knowledge can be helpful in telling a C4 or a C3 plant, external features hardly provide a clue for this. However, histological study of bundle sheath in the leaves can easily give clue about the plant type.
