Answer 1

Explanation:

The foliage leaves are characterised by green colour, thinness and flatness. They develop as protrusions from the shoot apex and are organs of limited growth. Leaves are very important vegetative organs, as they are chiefly concerned with the physiological process, photosynthesis and transpiration. Like other organs they also exhibit three tissue systems (Fig. 613).

Epidermal tissue system consists of the epidermal layers occurring on the adaxial (upper) and abaxial (lower) sides. Occurrence of stomata and outgrowths are distinctive features. The ground tissue system, as already reported in a preceding chapter, is known as mesophyll tissue.
