Fertilisation
Fertilisation is the fusion of male and female gametes to form a zygote.
Practice This ConceptMain explanation
Teacher explanation
Fertilisation is the stage after pollination in flowering plants and after sperm reaches the ovum in animals. It starts the formation of a new individual because the genetic material from two gametes combines in one cell called the zygote.
Example
In humans, the sperm fuses with the ovum in the oviduct to form a zygote.
Simple analogy
Fusion of gametes makes the zygote.
Common confusion
Students sometimes confuse fertilisation with pollination or even with implantation. The exact idea is gamete fusion.
Exam tip
If the question mentions fusion, zygote, or sperm and ovum joining, the answer is fertilisation.
