What is Pollination? Definition of Pollination Pollination is the transfer of pollen from the male part (anther) of a flower to the female part (stigma) of the same or another flower, enabling fertilization and seed production. Process of Pollination Pollination is a critical phase in the reproductive cycle of flowering plants, involving several key steps: … Read more
What is an Embryo Sac? Definition of Embryo Sac The embryo sac is the female gametophyte in flowering plants, located within the ovule, where fertilization occurs, leading to the development of the seed and endosperm. Structure of Embryo Sac The structure of the embryo sac, also known as the mature female gametophyte, is integral to … Read more
What is Ovule? Definition of Ovule An ovule is a small structure within the ovary of a plant that contains the female gamete (egg cell) and develops into a seed after fertilization.
