How does a flower become a fruit?
When pollen from a flower reaches the female part, a tube grows down and joins with a tiny egg cell inside the flower's base. This is fertilization. The base, called the ovary, swells and ripens, turning into a fruit that holds seeds. The petals fade because their job is done. Tomatoes, cucumbers, and pumpkins are all fruits that began as flowers.

Intro
Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. How does a flower become a fruit?
The Big Idea
Every tomato starts out as a flower! How does a flower become a fruit? Let's watch it change.
Pollen Arrives
Step one: Pollen Arrives. When pollen reaches the female part of a flower, a tiny tube grows down inside it. The tube joins with a tiny egg cell in the flower's base, which is called fertilization.
Swelling Up
Step two: Swelling Up. The base of the flower, called the ovary, swells and ripens. It turns into a fruit that holds seeds.
Petals Fade
Step three: Petals Fade. The petals fade, because their job is done. Tomatoes, cucumbers, and pumpkins are all fruits that began as flowers.
A Closer Look
Let's take a closer look! Opens up. Arrives. Swells. Holds seeds.
Quick Facts
Quick facts! A fruit's job is to protect seeds and help them travel. Cucumbers are fruits. Pumpkins began as flowers. Petals fade away.
Think Like a Scientist
Now, think like a scientist! Find a squash or tomato flower. Watch it each day. Notice when the petals fade. Look for the tiny fruit at its base. Draw how it changes.
Outro
When pollen reaches a flower's female part, a tube grows down to fertilize an egg cell. The flower's base, the ovary, swells into a fruit holding seeds, which is how tomatoes, cucumbers, and pumpkins begin. Science is amazing! Keep wondering and keep exploring!
