Content

Types of Aquatic Plants

1. Water Lilies: Floating leaves and flowers, adapted to live on the surface of water.
2. Cattails: Tall plants with long, slender leaves, adapted to grow in shallow water.
3. Duckweed: Small floating plants, adapted to rapid reproduction and floating on the water’s surface.
4. Water Hyacinth: Floating plants with large leaves and purple flowers, adapted to nutrient-rich water.

Types of Terrestrial Plants

1. Cacti: Succulent plants adapted to dry environments with thick stems for water storage.
2. Oaks: Large trees with broad leaves, adapted to moderate climates with deep roots for stability and nutrient uptake.
3. Grass: Plants with narrow leaves, adapted to various environments with rapid growth and recovery.
4. Fern: Plants with feathery leaves, adapted to shaded, moist environments.

Adaptive Features

• Aquatic Plants:
  • Floating Structures: Allows for gas exchange and light absorption (e.g., water lilies).
  • Water-logged Leaves: Helps in buoyancy (e.g., duckweed).
  • Root Adaptations: Anchors the plant in soft, wet soil (e.g., cattails).
• Terrestrial Plants:
  • Thick Cuticles: Reduces water loss (e.g., cacti).
  • Deep Roots: Accesses water and nutrients from deep soil layers (e.g., oaks).
  • Flexible Stems: Supports rapid growth and adapts to environmental changes (e.g., grass).

Draw Samples of Plants

Students will draw examples of at least two aquatic plants and two terrestrial plants, showing their adaptive features.

Class Activity Discussion (FAQs)

1. What are aquatic plants?
   Aquatic plants live in water and have features that help them float or stay submerged.
2. Can you name some examples of aquatic plants?
   Examples include water lilies, cattails, duckweed, and water hyacinth.
3. How do aquatic plants adapt to their environment?
   They have floating structures, water-logged leaves, and root adaptations.
4. What are terrestrial plants?
   Terrestrial plants grow on land and have features suited to various environments.
5. Give examples of terrestrial plants.
   Examples include cacti, oaks, grass, and ferns.
6. What adaptations do cacti have?
   Cacti have thick stems to store water and a thick cuticle to reduce water loss.
7. How do oak trees adapt to their environment?
   Oak trees have deep roots and broad leaves that help them survive in moderate climates.
8. What adaptation helps grass recover quickly?
   Grass has narrow leaves and can grow rapidly.
9. Why do ferns thrive in shaded areas?
   Ferns are adapted to moist, shaded environments with feathery leaves.
10. How does duckweed stay afloat?
    Duckweed has small, floating structures that help it stay on the water’s surface.

Presentation

• Step 1: The teacher revises the previous lesson on “Plant Forms.”
• Step 2: The teacher introduces the new topic: “Today, we will learn about aquatic and terrestrial plants and their adaptations.”
• Step 3: The teacher demonstrates how to draw and label examples of aquatic and terrestrial plants, highlighting their adaptive features.

Teacher’s Activities

• Show images or samples of aquatic and terrestrial plants.
• Explain the adaptive features of each plant type.
• Guide students in drawing and labeling their plant samples.

Learners’ Activities

• Identify and describe types of aquatic and terrestrial plants.
• Draw and label examples of these plants.
• Discuss the adaptive features in groups.

Assessment

1. Identify and describe two types of aquatic plants.
2. List and explain the adaptive features of terrestrial plants.
3. Draw and label examples of both aquatic and terrestrial plants.
4. Discuss how plants adapt to their environments.

Evaluation Questions

1. What are the two main types of plants we studied?
2. How do aquatic plants float on water?
3. What adaptations help cacti survive in dry conditions?
4. Name two adaptations of water lilies.
5. Describe the features of a typical terrestrial plant.
6. How does grass adapt to its environment?
7. What are the adaptive features of duckweed?
8. Explain why ferns grow well in shady places.
9. Draw and label a plant that lives in water.
10. Describe the adaptations of an oak tree.

Conclusion

The teacher summarizes the lesson by reviewing the types of plants and their adaptive features. Students are assigned to draw and describe additional examples of aquatic and terrestrial plants. The class activity is graded, and necessary corrections are made.
