What is Fertilization?
Fertilization is the union of a male and female gamete to form a zygote, which is the first cell of a new organism.
Process of Fertilization
1. In animals, the male gamete (sperm) is delivered to the female reproductive system through mating or artificial insemination.
2. The sperm swims through the female reproductive tract to reach the egg.
3. When the sperm reaches the egg, it penetrates the egg's protective layer and fuses with the egg, forming a zygote.
4. In plants, fertilization involves the transfer of pollen from the male reproductive organ to the female reproductive organ, leading to the formation of seeds.
Significance of Fertilization
Fertilization is essential for the continuation of a species. It combines genetic material from two parents to create genetic diversity in offspring.
Study Tips
- Understand the differences in the process of fertilization in plants and animals.
- Learn about the structures and functions of male and female reproductive organs involved in fertilization.
- Study the events that occur during the fusion of sperm and egg.
- Understand the importance of fertilization in the reproductive cycles of organisms.

LIFE SCIENCE
From Molecules to Organisms: Structures and Processes
Create representations to explain the unique and diverse life cycles of organisms other than humans (e.g., flowering plants, frogs, butterflies), including commonalities such as birth, growth, reproduction, and death.
Unity and Diversity
Construct an argument from evidence to explain the likelihood of an organism’s ability to survive when compared to the resources in a certain habitat (e.g., freshwater organisms survive well, less well, or not at all in saltwater; desert organisms survive well, less well, or not at all in woodlands).
Create models that illustrate how organisms and their habitats make up a system in which the parts depend on each other.
