Question

A is a closed vessel that contains an ovary in which eggs develop, fertilization occurs, and seeds mature

• A. Pollen sac
• B. Receptacle
• C. Microsporophyll
• D. Carpel

Answer 1

The correct option is D Carpel

Carpel is the female reproductive organ of a flower, consisting of an ovary, a stigma, and usually a style. A carpel is the female reproductive part of the flower, interpreted as modified leaves bearing structures called ovules, inside which the egg cells ultimately form. It may occur singly or as one of a group. Fertilization of an egg within a carpel by a pollen grain from another flower results in seed development within the carpel

So, the correct answer is 'carpel'
