Question

angiospermic plants are called highly evolved plants

Answer 1

Dear Student,

Angiosperms are highly evolved plants due to the following reasons:

1. Angiosperms are flowering plants. Their ovules develop in flowers.
2. Pollen grains are produced inside anther and ovules inside ovary.
3. Each embryo sac contains three antipodal cells, two synergids, and one egg cell.
4. Sexual reproduction involves double fertilization.
5. Double fertilization is a type of fertilization taking place in angiosperms where one sperm nucleus unites with the egg to form the diploid zygote (from which the embryo develops) and the other unites with two polar nuclei to form the triploid, primary endosperm nucleus.
6. Life cycle is diplontic type.
7. These are divided into two classes - dicotyledons and monocotyledons.
