double fertilization in angiosperms
Double fertilization in angiosperms involves the fusion of one sperm cell with an egg cell to form a zygote, leading to embryo development, and the fusion of another sperm cell with two polar nuclei to form a triploid cell, which develops into endosperm.
important role of flowers in plant sexual reproduction short answer
Flowers play a crucial role in plant sexual reproduction by facilitating pollination and subsequent fertilization. They attract pollinators through color, fragrance, and nectar, ensuring the transfer of pollen between male and female reproductive organs. This process leads to the formation of seeds, promoting genetic diversity and the continuation of plant species.
