Complete Lesson Plan
Learning Objectives
- •
Identify the different parts of a plant
- •
Describe the function of each plant part
- •
Explain why each part is important to the plant
- •
Label the parts of a plant correctly
Lesson Procedures
motivation
Show a real plant. Ask: 'What do you see? Can you name the parts of this plant? What do you think each part does?'
presentation
- •
Present a complete plant with visible parts
- •
1. ROOTS
- Located underground
- Functions:
- Absorb water and minerals from soil
- Hold the plant firmly in the ground
- Store food
- Example: Carrot roots store food we can eat
- •
2. STEM
- The main body of the plant
- Functions:
- Supports leaves, flowers, and fruits
- Transports water from roots to leaves
- Carries food from leaves to other parts
- Can be soft (like grass) or hard (like trees)
- •
3. LEAVES
- Usually green in color
- Functions:
- Make food for the plant (photosynthesis)
- Release oxygen into the air
- Help the plant breathe through tiny holes (stomata)
- Different shapes and sizes
- •
4. FLOWERS
- The colorful part of the plant
- Functions:
- Produce seeds
- Attract insects for pollination
- Help the plant reproduce
- Not all plants have flowers
- •
Use diagram to show all parts together
generalization
Questions:
- What are the four main parts of a plant?
- What does each part do?
- Why are all parts important?
- Can a plant live without one of these parts? Why or why not?
guided practice
- •
Label the plant diagram together on the board:
- Point to roots → students say 'ROOTS'
- Point to stem → students say 'STEM'
- Point to leaves → students say 'LEAVES'
- Point to flower → students say 'FLOWER'
- •
Match the part to its function:
| Plant Part | Function | |-----------|----------| | Roots | Makes food | | Stem | Absorbs water | | Leaves | Supports the plant | | Flower | Produces seeds |
(Correct matching)
- •
Show different plants and identify their parts:
- Mango tree: roots, trunk (stem), leaves, flowers
- Rose plant: roots, stem, leaves, flowers
independent practice
- •
Activity 1: Draw a plant and label all four parts
- •
Activity 2: Complete the table:
| Part | Function | |------|----------| | Roots | _________ | | Stem | _________ | | Leaves | _________ | | Flower | _________ |
- •
Activity 3: Circle the correct answer:
- Which part absorbs water? (roots / leaves / flower)
- Which part makes food? (stem / leaves / roots)
- Which part supports the plant? (flower / stem / leaves)
- •
Activity 4: Match the picture to the plant part name
preliminary activities
- •
Prayer and greetings
- •
Review: Living and non-living things
- •
Show pictures of different plants

Worksheets
assignment
Homework:
- Observe a plant at home and draw it with labels
- List 3 plants and identify if they have all four parts
- Write why plants need roots and leaves
Remarks:
- Use actual plant specimens for better understanding
- Take students outside to observe real plants if possible
subject matter
Topic: Parts and Functions of Plants
Key Concepts:
- Plants have four main parts: roots, stem, leaves, and flowers
- Roots - absorb water and nutrients from soil, anchor the plant
- Stem - supports the plant, transports water and nutrients
- Leaves - make food through photosynthesis, help plant breathe
- Flowers - produce seeds for reproduction
- Each part has a special job to keep the plant alive and healthy
Materials:
- Real plants or plant samples
- Plant diagram charts
- Pictures of different plants
- Manila paper
- Colored markers
- Magnifying glass
