Lesson 124: Parts of a plant

🔬 SCIENCE (40 Lessons) • 🟢 A. Living and Nonliving

← Back to Level 1

Objective

I can name the main parts of a plant and tell what each part does. I can talk about roots, stem, leaves, and flower using simple science words.

Materials

Mini-lesson — What are the parts of a plant?

A plant is a living thing. It needs sunlight, water, and air to stay alive and grow.

Four main parts of a plant

  • Roots — grow under the soil. They hold the plant in place and drink water from the ground.
  • Stem — holds the plant up. It carries water from the roots to the leaves and flowers.
  • Leaves — are usually green. They use sunlight, air, and water to help the plant make its own food.
  • Flower — is the colourful part. Flowers can grow into fruits and seeds so new plants can grow.

All the parts work together

  • Roots take in water.
  • The stem carries water up.
  • Leaves make food with sunlight.
  • Flowers help the plant make seeds.

When you look at a plant, try to point to the roots, stem, leaves, and flower and say what job each part does.

Guided Practice — Label the parts of a plant

You will look at a real plant (or a picture) and practise saying and writing the names of each part.

  1. Look closely: Point to the roots, stem, leaves, and flower if there is one.
  2. Say the names: Slowly say each word: "roots", "stem", "leaves", "flower".
  3. Draw a simple plant: On your paper, draw soil, roots, a stem, some leaves, and a flower on top.
  4. Label each part: Draw a little line and write the word next to each part (for example: root, stem, leaf, flower).
  5. Talk about jobs: For each label, say what that part does in one short sentence.
  6. Use the tracing pad: Choose words like plant, root, stem, or leaf from the dropdown and trace them slowly while you say the word.
  7. Add one sentence: Under your drawing, write one simple sentence such as "Roots drink water" or "Leaves need sun".

Tip: After you trace the words, write one sentence, such as "Roots drink water" or "Leaves make food".

Practice 1 — Match part to job

Draw a simple plant and write these words on the side: roots, stem, leaves, flower. Then match each part to its job.

Draw a tiny picture or symbol next to each word to help you remember (for example, a drop of water near roots or a sun near leaves).

Practice 2 — Plants where you live

Look out a window or in your garden (or look at pictures of plants). Choose one plant.

  1. Draw the plant as best you can.
  2. Show where you think the roots are under the soil.
  3. Label the stem, leaves, and flower if you can see one.
  4. Circle the part that you think is working hardest today (for example the leaves in the sun).
  5. Tell a grown-up one thing you notice about that part.

Practice 3 — What if a part is missing?

Think about what might happen if a plant loses one of its parts. Talk or write a short idea for each question.

Use simple ideas like "It could not drink water" or "It could not make seeds".

Quick Check — Parts of a plant

Answer each question about plants and their parts. Think about what each part does.

1) Which is a living thing?

A plant is living. A toy car and a plastic flower are nonliving.

2) Which list shows parts of a plant?

Roots, stem, leaves, and flower are main parts of a plant.

3) What is the job of the roots?

Roots take in water from the soil and hold the plant in place.

4) Where do the roots grow?

Roots grow under the soil.

5) What is one job of the stem?

The stem holds the plant up and carries water from the roots.

6) Which part is usually green and makes food?

Leaves are usually green and help the plant make food.

7) What do leaves need to help make food?

Leaves use sunlight, air, and water to help the plant make food.

8) Which part of the plant can grow into fruit or seeds?

Flowers can turn into fruits and seeds.

9) A plant is in very dark shade all day. Which part may not work well?

Leaves need sunlight, so they may not work well in deep shade.

10) Which picture would best show roots?

Roots look like thin lines growing under the soil.

11) A child says, "The stem is like a straw." What do they mean?

A straw carries drink up; the stem carries water up the plant.

12) Which set mixes plant parts and their jobs correctly?

Roots take water, the stem carries it, and leaves help make food.

13) Why does a plant need roots to stay in one place?

Roots act like anchors and hold the plant in the soil.

14) Why do we learn the names of plant parts?

Knowing the names helps us understand and care for plants.

15) A plant has strong roots, a tall stem, and many green leaves. What does this most likely mean?

Healthy roots, stem, and leaves show that the plant parts are working well.
