Question

An anther dehiscence towards the periphery of the flower is known as

• A. Extrose
• B. Introse
• C. Both A and B
• D. None of the above

Answer 1

Answer: (A)

Extrose

There are modes of dehiscence of the anthers found in the case of angiospermic flowers. Extrose is the form of dehiscence which is in the outward direction. The anthers break and the pollen grains are liberated away from the center of the flower. There is a movement of the pollen grains towards the periphery of the flower. In case of Argemone, there is an extrose form of dehiscence.

Thus, the correct answer is option A.
