Sperm and egg cells are super important for making new life. They work together during a process called fertilization. Let’s break it down!

Sperm Cells

• Shape and Size: Sperm cells are tiny and shaped like little tadpoles, which helps them swim. They have a tail that lets them move quickly to find the egg.
• Function: The main job of sperm is to carry genetic information from the male. Each sperm has half of what is needed to create a new person.

Egg Cells

• Size and Structure: Egg cells are much bigger and rounder than sperm cells. They also have special nutrients that help the baby grow in the early stages.
• Function: The egg not only brings genetic information but also provides a safe place for the new baby to develop.

Fertilization

When a sperm successfully connects with an egg, this is called fertilization. It creates something called a zygote. The zygote then starts dividing into more cells and eventually grows into a new organism.

In short, sperm and egg cells are key players in continuing life by bringing together genetic information!
