Question

Name two unique features regarding the reproduction of flowering plants.

Answer 1

1. Double Fertilization: It involves the fusion of one male gamete with the egg to form a zygote and the fusion of the other male gamete with two polar nuclei to form a triploid endosperm. This is a unique characteristic of angiosperms.
2. Formation of Pollen Tube: After pollination, the pollen grain germinates on the stigma and grows a pollen tube that delivers male gametes to the ovule for fertilization, allowing reproduction without the need for water.
