Question

A leaf showing stomata and cuticle on upper epidermis, raphides in the mesophyll and diaphragm cells, belongs to a plant that probably is a :

Answer 1

Hydrophyte have characteristics like :

1. Thin cuticle
2. Stomata open most of time (as water is abundant)
3. Increased number of stomata
4. Plants in water have less structure (water pressure supports them)
5. Large flat leaves on surface plants for flotation
6. Air sacs for flotation
7. Reduction in roots ($H_{2}O$ can diffuse directly into leaves)
8. Roots of water plants are feathery to hold up plant
9. Roots modified to pick up oxygen

Submerged hydrophytes do not have stomata. Mesophytes have stomata on lower epidermis. Xerophytes have covered stomata by small hair to reduce loss of water.

So, the correct answer is "option A"
