Content:
Plants’ Reproduction:
- Meaning:
- Reproduction is how plants make new plants.
- Plants can make babies to grow into new plants.
- Types of Reproduction:
- Sexual Reproduction:
- Plants make seeds by joining pollen (from male) with eggs (from female).
- Example: Apple trees produce seeds through flowers.
- Asexual Reproduction:
- Plants make new plants without seeds.
- No need for pollen and eggs.
- Sexual Reproduction:
- Types of Asexual Reproduction:
- 1. Cutting:
- Pieces of a plant can grow into new plants.
- Example: Rose stems can grow into new rose plants.
- 2. Runners:
- Plants send out shoots that become new plants.
- Example: Strawberries make runners for new strawberry plants.
- 3. Tubers:
- Plants grow new plants from underground stems.
- Example: Potatoes grow new plants from their “eyes.”
- 4. Bulbs:
- Plants make new plants from bulbs underground.
- Example: Tulips grow from bulbs in the ground.
- 5. Suckers:
- New shoots grow from the plant’s base.
- Example: Some fruit trees create new trees from suckers.
- 1. Cutting:
Remember, plants have cool ways to become new plants! 🌱

Presentation:
- Step 1 – Introduction (5 minutes):
- Define reproduction and its importance in plants.
- Briefly explain sexual and asexual reproduction.
- Step 2 – Differentiating Sexual and Asexual Reproduction (10 minutes):
- Discuss the process of sexual reproduction involving pollen and seeds.
- Introduce asexual reproduction and its characteristics.
- Step 3 – Types of Asexual Reproduction (15 minutes):
- Discuss five types: Cutting, Runners, Tubers, Bulbs, and Suckers.
- Provide examples and show corresponding pictures.
- Step 4 – Teacher’s Activities (5 minutes):
- Encourage questions and participation.
- Clarify any doubts.
- Step 5 – Learners’ Activities (10 minutes):
- Group activity: Classify given examples as sexual or asexual reproduction.
- Discuss findings as a class.
Strategies and Activities:
- Use visuals to enhance understanding.
- Encourage group discussions to promote peer learning.
- Relate examples to everyday experiences.
Conclusion:
- Summarize key points: plant reproduction, sexual vs. asexual, types of asexual reproduction.
Assessment (Evaluation):
