Question

Stomata in Water Lily and Podostenon occur respectively

• A. Lower leaf surface and absent
• B. Upper leaf surface and absent
• C. Both leaf surface and upper part
• D. Absent in both

Answer 1

The correct option is B Upper leaf surface and absent

Water lily and Podostemon are hydrophytes. In Waterlily, Root system is fixed at the bottom of the pond, leaves float on the surface of the water. So the stomata are present on the upper surface or epidermis. Podostemon is submerged rooted hydrophyte, in which stomata are absent.

So, the correct option is ‘Upper surface and absent’.
