Mention the parts observed in a well-stained temporary mount of leaf peel when focused under high power of a microscope
Answers
1. The epidermal cells are visible. These are irregular in outline and have no intercellular spaces.
2. Many small pores (stomata) are seen scattered among the epidermal cells.
3. Each pore is guarded by two bean-shaped guard cells, each containing chloroplasts and a nucleus.
4. The inner concave boundary of each guard cell is thick, whereas its outer boundary is thin.
5. The stomata may be open or closed. The guard cells regulate the opening and closing of the stomata.
Parts observed for a leaf peel are:
i) A layer of cells are seen which maybe irregular or rectangular according to the leaf type. This is the epidermis without any intercellular spaces.
ii) Few too many small pores or stomata can be seen.
iii) These pores can be open or closed.
iv) Each pore can be seen to be guard on both sides by bean-shaped cells known as guard cells.
v) The guard cells contain a nucleus.
