---
**Introduction (10 minutes):**
1. **Greetings and Attendance:**
- Take attendance and greet the students.
2. **Review of Previous Lesson:**
- Briefly review the previous topic discussed in class.
3. **Introduction to Asexual Propagation:**
- Display the lesson objectives on the whiteboard or screen.

**Direct Instruction (15 minutes):**
1. **Definition:**
- Explain that asexual propagation is a method of plant reproduction that does not involve the fusion of gametes. Instead, it relies on the vegetative parts of plants to produce new plants.
2. **Methods of Asexual Propagation:**
- **Cuttings:** Explain and show examples of stem, leaf, and root cuttings.
- **Layering:** Explain simple and air layering techniques.
- **Division:** Describe how plants like bulbs, tubers, and rhizomes are divided.
- **Grafting:** Explain grafting and its types—cleft, whip, and tongue grafting.
- **Budding:** Explain the method of budding, focusing on T-budding and chip budding.
- **Micropropagation:** Briefly introduce tissue culture as a method of asexual propagation.
3. **Visual Aids:**
- Use a PowerPoint presentation and video to demonstrate these methods.
- Show actual plant materials and tools if available.

**Activity/Practical (15 minutes):**
1. **Hands-On Demonstration:**
- Demonstrate how to take a cutting from a plant.
- Allow students to practice taking cuttings from available plants.
2. **Group Activity:**
- Divide students into small groups and assign each group a different method of asexual propagation.
- Provide materials for each group to perform their assigned method (e.g., bulbs, soil, water).
3. **Class Discussion:**
- Have each group present their method and explain the steps involved.
- Encourage students to ask questions and discuss the advantages and limitations of each method.
---
**Conclusion (10 minutes):**
1. **Recap:**
- Summarize the key points discussed in the lesson, emphasizing the different methods of asexual propagation.
- Highlight the importance of asexual propagation in agriculture, such as uniformity of crops and faster reproduction.
2. **Q&A:**
- Open the floor for any questions.
3. **Assessment:**
- Distribute a short quiz or worksheet to assess students' understanding of the lesson.
- Collect group activity sheets with brief descriptions and observations from the practical activity.
4. **Homework:**
- Assign students to select one method of asexual propagation and write a detailed report on it, including diagrams and real-world examples.
---
**Assessment:**
- Participation in group activity and class discussion
- Performance in the practical demonstration
- Responses in the quiz or worksheet
---
**Closing:**
- Thank students for their participation.
- Provide a brief preview of the next lesson.
