🌿 Plant Parts & Growth: The Secret Life of Green Things
Discover the amazing parts of a plant and learn how a tiny seed grows into a tall, leafy plant. This lesson explores roots, stems, leaves, flowers, and everything plants need to grow!
Learning Goals
By the end of this lesson, you will be able to:
✓
Name the main parts of a plant and what each part does
✓
Explain the steps a seed takes to grow into a plant
✓
Describe the four things plants need to grow strong and healthy
Before You Start
Before this lesson, you should know:
→
You should know that plants are living things that grow and change
→
You should know that living things need food, water, and air to survive
→
You should be able to observe things carefully, like looking at a plant in a garden or park
Here are a few things that will help you with today's lesson.
Key Words
Important words to know for this lesson:
Roots
The part of a plant that grows under the ground. Roots soak up water and hold the plant in place, like an anchor.
Stem
The part that holds the plant up and carries water from the roots to the leaves, like a straw.
Leaves
The flat, green parts that make food for the plant using sunlight.
Flower
The colorful part of a plant that helps it make seeds to grow new plants.
Germinate
When a seed starts to sprout and grow into a baby plant.
Meet the Parts of a Plant! 🌻
A plant is made of different parts, and each part has a special job that helps the plant live, grow, and make new plants.
Roots dig down: Roots grow into the soil to drink water and grab tiny bits of food. They also hold the plant steady, like the roots of your favorite tree during a windy soccer game.
Stem stands tall: The stem works like a straw, carrying water and food up from the roots to the rest of the plant. It also keeps the plant standing up straight.
Leaves make food: Leaves catch sunlight and use it to make food for the plant. This is like the plant's own kitchen that never closes!
Flowers make seeds: Flowers attract bees and butterflies, and they help the plant make seeds. Those seeds can grow into brand new plants.
Plants need four things: To grow, plants need sunlight, water, air, and healthy soil. Take away any one of these and the plant will have trouble growing.
Example
Think of a sunflower. Its roots pull water from the soil, its tall stem holds it up, its leaves soak up sunshine to make food, and its big yellow flower makes seeds that birds love to eat. 🌻

This diagram shows a plant with its roots, stem, leaves, and flower, plus the sun that gives it energy.
Let's Try It Together!
Basic
A plant has these parts: roots, stem, leaves, and flower. Which part takes in water from the soil?
Let's Try a Harder One!
Intermediate
A bean seed was planted. After day 3 it sprouted roots, after day 6 it grew a stem, and after day 9 it grew leaves. In what order do these parts grow, and which comes first?
Your Turn to Practice
Try this one yourself — use the hint if you get stuck:
Maria notices her sunflower is turning brown and drooping. The soil is very dry. Which plant part is not getting what it needs, and what does it need?
In the Real World
🥕
When you eat a carrot, you are eating a plant's root that stored food underground!
🌻
Farmers plant sunflower seeds and watch the flowers turn to follow the sun across the sky.
🍎
Apples grow from the flower of an apple tree — the fruit holds the seeds for new trees.

Challenge Question
Optional
Stretch your brain — this one's a bit harder!
A bean seed is planted in a dark closet with water but no light. The stem grows but the leaves stay pale and yellow instead of green. Why do you think this happened?
Key Takeaways
1.Plants have different parts: roots, stem, leaves, flowers, and seeds — each with its own job.
2.Roots soak up water and hold the plant in place, the stem carries water up, and leaves make food using sunlight.
3.Plants need sunlight, water, and air to grow healthy and strong.
4.Flowers help make seeds, and seeds grow into brand new plants!
