What is Fertilization?
When pollen from the anther of the stamen joins with the ovules present in the ovary, it is called fertilization. Strasburger discovered fertilization for the first time in 1884. In angiosperms, the female gametophyte (embryo sac) is located in the ovule. As a result, pollens that reach the stigma form a pollen tube, which helps the delivery of male gametes deep into the embryo sac from the stigma. The developing pollen tube penetrates the stigmatic tissue, moves through the style, and then goes down the ovarian wall.
Fertilization in Plants
Fertilization is the fusion of a male gamete carried by pollen with a female gamete present in the ovule to form a diploid zygote, which later develops into an embryo. The process of Fertilization involves some pre-steps like pollination and germination On reaching the stigma, the pollen grain containing two nuclei germinates to produce the pollen tube. The pollen tube grows down into the style, deriving nutrition from it. The generative nucleus divides mitotically into two male gametes. The male gametes fuse with the ovules to form the zygote. In this article, we will study fertilization in plants in detail including its process, types, and Post fertilization development.
