Read the following statements carefully and select the correct one.
1 The process of photosynthesis requires oxygen
2 The system of xylem vessels from the root to the leaf vein can supply the needed water
3 The gradient is transmitted into the photosynthetic cells and on the water- filled phloem in the leaf base
4 Tensile strength is an ability to resist a pushing force
Explanation:
The system of xylem vessels from the root to the leaf vein can supply the needed water, is the correct statement.

Where are stomata located on an isobilateral leaf?
1 Upper epidermis
2 Lower epidermis
3 Upper and lower epidermis
4 None of the above
Explanation:
In an isobilateral (often monocotyledonous) leaf they are about equal on both surfaces.

In land plants, the guard cells differ from other epidermal cells in having
1 Mitochondria
2 Endoplasmic reticulum
3 Chloroplast
4 Cytoskeleton
Explanation:
The guard cells of land plants are specialised epidermal cells which contain chloroplast. In rest of the epidermal cells, chloroplast are absent. Even though guard cells have chloroplast they are poor in performing photosynthesis as there is absence of NADP reductase enzyme.
