Question

Give reasons In fully submerged plants stomata are absent and no waxy coating in the leaves.

Answer 1

Answer:

Explanation:

A waxy cuticle will either be very thin if present or not present at all because there is no need to conserve water in a submerged leaf as there is an abundance of water. ... Stomata are generally high in presence on the upper epidermis of floating leaves because transpiration is constant in these plants.

Answer 2

Answer:

Hydrophytes (ex.

water ferns) are submerge aquatic plants that do not have stomata. Instead of stomata, the plants surface cells are capable of absorbing water, nutrients, and dissolved gases in the water.

Technically, because these plants lack such structural support, they should be under threat of being submerged or getting swept away by the wind. But the waxy coating on the leaves of these plants holds them up and does not let them sink into the water.
