Leaves of grasses roll and unroll due to:
1 hormonal change
2 change in temperature
3 change in turgor pressure
4 presence of bulliform apparatus
Explanation:
D Leaves of grasses roll and unroll due to presence of bulliform apparatus. Bulliform cells are a group of large parenchyma cells that specifically exist on the upper surfaces of leaves of many monocots.
