A) increasing the absorptive surface of the cell
B) checking transpiration
C) mechanical support
D) photosynthesis
Correct Answer: C
Solution :
Sclerenchyma cells are thick walled, lignified and dead at maturity. These provide mechanical support to the Pinus needle. Sclerenchyma may be fibres or sclereid. The epidermis is covered on the outside by a thick cuticle which help in checking transpiration. The parenchymatous mesophyll consists of thin walled cells which contain numerous chloroplasts and thus photosynthetic in function.
