Mini Lesson
Plants can't walk, talk, or eat at a table — but every single part of a plant has an important job that keeps it alive and growing!
Roots — the anchor and drinker
- Roots grow underground and hold the plant firmly in the soil.
- They soak up water and nutrients from the soil and send them up the plant.
- Example: Carrots and beets are roots we can eat.
Stem — the highway
- The stem supports the plant and holds it upright.
- It carries water and nutrients from the roots to the leaves and flowers — like a straw.
Leaves — the food factory
- Leaves capture sunlight and use it — along with water and air — to make food for the plant.
- This process is called photosynthesis.
Flower and Seed
- The flower attracts insects that help the plant reproduce.
- The seed is made inside the flower; it can grow into a brand-new plant.
💡
Ask yourself: Which part drinks water? Which part makes food? Which part makes new plants?

Root
The underground part of a plant that absorbs water and nutrientse.g. A carrot is a root.

Flower
The colorful part that attracts insects and makes seedse.g. A rose is a flower.
Seed
A small part made by a flower that can grow into a new plante.g. An apple seed can grow into an apple tree.
