Question

In submerged hydrophytes/Vallisneria the functional stomata are found

• A. On the upper leaf surface
• B. On the lower leaf surface
• C. Both leaf surfaces
• D. No where on the plant

Answer 1

The correct option is D No where on the plant

Some aquatic plants have stomata and some do not. 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. Submerged leaves of aquatic plants are astomatic. Stomata are either absent or vestigial.

So, the correct answer is 'No where on the plant.'
