Question

The megasporangium of the angiosperms on maturation gives rise to

• A. Cotyledons
• B. Seed
• C. Fruit
• D. Endosperm

Answer 1

Answer: (B)

In the angiosperms, ovule is found that contains embryo sac. Ovule is the basis of female reproductive structure that further develops into a seed after fertilization. It consists of a megasporangium surrounded by one or two layers of tissue called integuments. The megasporangium produces spores that develop into megagametophyte. The megagametophyte produce one or more egg cells. Pollen grains enter the ovule through an opening called micropyle and fertilize the egg cells. The resulting embryo develops within the ovule and becomes a seed.
