Student lesson
Words to know
the part that holds the plant and takes in water
the part that holds the plant up and carries water
the part that catches light to make food
the part that makes seeds
1. Discover: The garden plant
Esi carefully lifts a small weed from the school garden with her teacher. It has white roots, a green stem, leaves and one tiny yellow flower. “Every part has a job,” says her teacher. “And the parts work as a team.”
Think: Which part took in the water?
2. Understand: Plant parts and jobs
Idea 1: Roots and stem
The roots grow in the soil. They hold the plant and take in water. The stem holds the plant up and carries water to the leaves and flowers.
Idea 2: Leaves, flower and fruit
Leaves catch light to help the plant make food. The flower may make seeds. After the flower, a fruit may grow with seeds inside.
Idea 3: A team
The parts work together. Water goes up from the roots, light is caught by the leaves and food is shared around the plant. If one part is damaged, the whole plant can suffer.
3. Worked examples
Example 1 (I show you): Match part and job
Root, stem, leaf.
- Root: water and hold.
- Stem: carry and hold up.
- Leaf: catch light.
Answer: Root takes in water, stem carries it, leaf catches light.
Example 2 (We do it together): What if a part is damaged?
A leaf is eaten.
- Less light is caught.
- Less food is made.
- The plant may grow slowly.
Answer: Damaged leaves mean less food for the plant.
Example 3 (You try): Label
Draw a plant.
Show the steps and answer
- Draw the plant large.
- Add label lines with a ruler.
- Write a title.
Answer: A labelled plant with title.
Did you know?
The roots of a tree can spread as wide as the tree is tall.
Why this matters
Knowing plant parts helps us understand how plants grow and how to care for them.
4. Explore: Plant dissection
Look carefully at a whole weed with an adult.
- An adult lifts a small weed with roots.
- Draw it large.
- Label root, stem, leaf and flower.
- Say the job of each part.
Think about it: what did you notice?
What did you notice? Each part is different.

Courseversity badge thresholds (overall quiz score): Gold = 90–100%; Silver = 80–89.9%; Bronze = 70–79.9%. A badge is never a full record of progress.
If a learner struggles
- Find the misconception: “Only the flower matters.” All parts matter.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Name and show the jobs of three plant parts.
- Guided practice: work through one example together and let the learner try the next one.
- Reassess: use the quiz again or the worksheet.
- Move on when the learner shows Silver-level evidence independently.
For parents and guardians
In this lesson your child reviews plant parts and what each part does. You do not need to be an expert to help.
- Look at a plant together.
- Ask, “What does the root do?”
- Draw a plant with labels.
- Ask “how do you know?” after each answer, and listen.
- Praise effort, not only right answers. Mistakes are how we learn.
- Ten to fifteen minutes a day is better than one long session.
Teacher package
1–5. Objectives, prerequisites, materials, preparation, duration
Lesson objectives. Learners will: name root, stem, leaf, flower, fruit and seed; say the job of each part; draw and label a plant; explain how parts work together.
Prerequisite knowledge. Grade 1 ideas: plant parts (root, stem, leaf, flower), what plants need and caring for plants.
Materials. A whole small weed with roots, paper, pencils and rulers. Low-resource options: use chalk or charcoal on a board or wall, drawings in the sand, and objects from the classroom instead of printed materials.
Preparation. Have an adult dig up a small weed. Place it on a tray. Prepare a labelling sheet.
Suggested duration. 45–60 minutes. It can be split into two shorter sessions.
6–9. Teaching procedure, explanation notes, guided and independent activities
Introduction (5 min). Show a plant and ask, “What are the parts?”
Explanation (10 min). Teach parts and jobs.
Guided activity (10 min). Learners draw and label.
Independent activity (10 min). Learners explain teamwork.
Assessment and reflection (5 min). Ask each learner to say one thing they learned and how they know it.
Key questions. What part is this? What does it do?
Teacher explanation notes. Start with real objects and safe, hands-on observation. Then talk about what was seen, then draw and write. Always say “how do you know?”. Keep to the safety notes, and use local, safe materials.
10–12. Differentiation, formative assessment, common misconceptions
Support. Use real objects and pictures, short sentences and a partner. Let learners point, show or draw instead of writing. Extension. Ask learners to find a new example at home and explain how they know.
Formative assessment. Listen to learners read and explain, ask “how do you know?”, and check the independent work.
Misconceptions. “Only the flower matters.” All parts matter.
13–15. Assessment questions, answer keys, marking scheme
Use the quiz, the 14-mark exam practice and the worksheet on this page. All answers and marking guides are in the answer sections above. Re-check every answer before use.
16–19. Remediation, enrichment, homework, teacher reflection
Remediation. Name and show the jobs of three plant parts. Enrichment. Look for one new example near your home or school, draw it and explain it to someone. Homework. See above.
Teacher reflection. After teaching, record: which ideas learners understood; which misconceptions occurred; which activities worked; which learners need more practice; and what to improve next time.
