Question

• A. Potato type
• B. Oat type
• C. Apple-mulberry type
• D. Nymphaea type

Answer 1

The correct option is A Potato type

Stomata are tiny pores present on the leaf surface that helps in gas exchange. There are five types of stomata depending upon their distribution on the leaf surface. These are potato type, oat type, apple-mulberry type, water lily type and potamogeton type. In potato type, a leaf has more stomata on the lower surface. In apple type, stomata are present only on the lower side. In oat type, stomata are equally distributed on both the sides. In water lily type, stomata are present only on the upper surface. In potamogeton type, stomata are generally absent.

Thus, the correct answer is option A.
