Question

Identify the Cleistogamous flowers in Viola.

• A.
• B.
• C.

Answer 1

The correct option is A

Viola produces two types of flowers - chamogamous flowers and cleistoganous flowers.
Chasmogamous flowers open and expose the reproductive structures enabling cross pollination. These flowers are found well above the ground.
Cleistogamous flowers remain closed keeping the gametes sequestered to ensure self-pollination. Flowers open only after fertilisation. These flowers are found at the ground level.
