FAQ’s – Fertilization in Plants
1. What happens after a Plant is Fertilized?
After fertilization, the cells of the zygote begin dividing, and the zygote develops into an embryo, or developing plant. The embryo is stored in a seed capsule, where it remains dormant until environmental conditions support its development into a new plant.
2. Which Types of plants show Double Fertilization?
Double fertilization is unique to flowering plants (angiosperms) and is responsible for the formation of both the embryo and its potential food source in the seed. Ephedra and Gnetum are exceptions to gymnosperms as they show double fertilization.
3. Which Plants show Self-Fertilization?
Orchids, peas, sunflowers, and tridax are just a few of the plants that may self-pollinate. The majority of self-pollinating plants have small, inconspicuous blooms that release pollen straight onto the stigma before the bud opens.
4. What happens to Plants without Fertilization?
The pollination of a flower triggers the female reproductive organs to mature into fruit. However, without fertilization, as we know, there will be no seed development. Production of the plant without fertilization is done by vegetative propagation.
5. Why is Fertilization Important for Plants?
Double fertilization provides stimulus to the plant, resulting in the ovarian development of fruits and the development of ovules into the seed. When the haploid male gametes and female gametes fuse, the diploid state of the plant is restored.
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.
