Understanding Fertilization in Flowering Plants
Fertilization is a crucial step in the reproduction of flowering plants. It involves the fusion of male and female gametes.
Key Steps in Fertilization
- The pollen grain contains the male germ-cells (gametes).
- When pollen lands on the stigma, it germinates and a pollen tube grows towards the ovule.
- One male germ-cell travels through the pollen tube and fuses with the female gamete (egg cell) located inside the ovule.
Result of Fusion
The fusion of the male germ-cell and the female gamete results in the formation of a diploid cell called the Zygote. This zygote will eventually develop into the embryo of a new plant.
Therefore, when the male germ-cell from the pollen grain fuses with the female gamete in flowering plants, a Zygote is formed.
Important Questions from Botany
One advantage of sexual reproduction over asexual reproduction is that it helps species to survive over long evolutionary time. This is because sexual reproduction produces :
