1. | Protecting the plant from salt stress. |
2. | Increased photosynthesis in monocots. |
3. | Providing large spaces for storage of sugars. |
4. | Inward curling of leaves in monocots. |
Large, empty colourless cells of the adaxial epidermis along the veins of grass leaves are:
1. | Lenticels | 2. | Guard cells |
3. | Bundle sheath cells | 4. | Bulliform cells |
Grass leaves curl inwards during very dry weather. Select the most appropriate reason from the following :
1. Tyloses in vessels
2. Closure of stomata
3. Flaccidity of bulliform cells
4. Shrinkage of air spaces in spongy mesophyll
