A student observes grass and Hibiscus plants in his garden during noon. To his surprise, only the leaves of grass were found rolled inwards. The reason could be.
1 presence of more number of stomata on the grass leaves.
2 undifferentiated mesophyll in grass leaves
3 presence of Bulliform cells in the grass leaves
4 due to higher rate of transpiration.
Explanation:
C In grasses, certain adaxial epidermis have a large, empty, colourless cells, called bulliform cells. When the bulliform cells in the leaves have absorbed water and are turgid, the leaf surface is exposed. When they are flaccid due to water stress, they make the leaves curl inward to minimize water loss.

Which one of the following anatomical structures is involved in guttation?
1 Cuticle
2 Hydathodes
3 Lenticels
4 Stomata
Explanation:
B The loss of water in the form of droplets from margins of leaves is called as guttation. The absorption of water exceeds that of the transpiration due to which, root pressure is increased in xylem and water comes out through hydathodes.

A leaf is identified by:
1 flat green lamina
2 presence of axillary buds
3 presence of leaf blade and petiole
4 none of the above
Explanation:
B A leaf is identified by flat green lamina. A broad expanded blade (the lamina) attached to the plant stem by a stalk like petiole. The axil of the leaf is the upper angle between the leaf and the stem. Structures located there are called axillary. It is often the location of a bud so that bud is known as axillary bud.
