Sexual Reproduction Fuses Two Distinct Gametes Into a Zygote

The fusion of two distinct gametes creates a zygote, the first cell of a new organism.
1. Sperm is the male gamete.
2. Egg is the female gamete.

Definition

Zygote

A eukaryotic cell formed by the fusion of two gametes.

Analogy

Think of sperm as the messenger and the egg as the receiver.
The sperm travels to deliver genetic information, while the egg provides the environment for development.

Male and Female Gametes Differ in Size, Energy, and Number

Size and structure:
1. Sperm: small and streamlined, built for mobility.
2. Egg: large and nutrient-rich, providing sustenance for the developing embryo.
Energy reserves:
1. Sperm: minimal reserves, built for short-term function.
