LEARNING OBJECTIVES

By the end of the lesson, pupils should be able to:

1. Explain the meaning of pollination.

2. Mention the types of pollination.

3. Identify agents of pollination.

4. Describe the process of pollination.

5. Appreciate the importance of pollination in plant reproduction.

ENTRY BEHAVIOUR

Pupils have previously learned about reproduction in plants, the parts of a flower, and the functions of the ovary and ovules in seed and fruit formation.

This lesson builds on that knowledge by explaining how pollen is transferred from the anther to the stigma through pollination, which leads to fertilization and the production of seeds and fruits.

INSTRUCTIONAL MATERIALS

The teacher will teach the lesson with the aid of:

1. Flower diagrams

2. Real flowers

3. Pictures of bees, butterflies, and wind

4. Charts showing pollination process

5. Blackboard/whiteboard

METHOD OF TEACHING

Choose a suitable and appropriate methods for the lessons.

Note – Irrespective of choosing methods of teaching, always introduce an activities that will arouse pupil’s interest or lead them to the lessons.

CONTENT OF THE LESSON

INTRODUCTION

Plants produce flowers to help them reproduce and form seeds and fruits. For this to happen, pollen grains must move from one part of the flower to another.

This movement of pollen is very important because it leads to the production of seeds that grow into new plants.

In this lesson, pupils will learn about the meaning of pollination, types of pollination, agents of pollination, and the process of pollination.

MEANING OF POLLINATION

Pollination is the transfer of pollen grains from the anther (male part) to the stigma (female part) of a flower.

TYPES OF POLLINATION

1. Self-Pollination

Occurs when pollen is transferred from the anther to the stigma of the same flower or another flower on the same plant.

2. Cross-Pollination

Occurs when pollen is transferred from the anther of one flower to the stigma of a flower on a different plant of the same species.

AGENTS OF POLLINATION

The agents of pollination are: Insects (bees, butterflies), Wind, Water, Birds and Human beings

1. Insects (Bees, Butterflies) – Insects carry pollen grains from one flower to another when they move from flower to flower in search of nectar.

2. Wind – Wind blows pollen grains from the anther of one flower to the stigma of another flower.

3. Water – Water carries pollen grains from one flower to another, especially in water plants.

4. Birds – Birds transfer pollen grains when they move from flower to flower while feeding on nectar.

5. Human Beings – Humans help pollination by manually transferring pollen grains from one flower to another during farming or plant breeding.

PROCESS OF POLLINATION

1. Pollen grains are produced in the anther.

2. Pollen grains are transferred by agents like wind or insects.

3. Pollen lands on the stigma of a flower.

4. Fertilization begins, leading to seed and fruit formation.

SUMMARY

In this lesson, pupils learned that pollination is the transfer of pollen grains from the anther (male part) to the stigma (female part) of a flower.

They also learned the two types of pollination:

Self-pollination – transfer of pollen within the same flower or plant.

Cross-pollination – transfer of pollen from one plant to another plant of the same species.

Pupils further learned about the agents of pollination, such as:

Insects (bees, butterflies)

Wind

Water

Birds

Humans

Finally, they learned that pollination is important because it leads to fertilization, which produces seeds and fruits for new plant growth.

PRESENTATION

To deliver the lesson, the teacher adopts the following steps:

1. The teacher shows pupils a flower diagram or real flower.

Pupils’ Activities: Pupils observe the flower carefully.

2. The teacher asks pupils how plants produce seeds and fruits.

Pupils’ Activities: Pupils respond based on their previous knowledge.

3. The teacher introduces the topic: Pollination in Plants.

Pupils’ Activities: Pupils repeat the topic.

4. The teacher explains the meaning of pollination.

Pupils’ Activities: Pupils listen and take notes.

5. The teacher explains self-pollination and cross-pollination using diagrams.

Pupils’ Activities: Pupils identify differences between both types.

6. The teacher discusses agents of pollination such as insects, wind, and water.

Pupils’ Activities: Pupils mention examples around them.

7. The teacher explains the process of pollination step by step.

Pupils’ Activities: Pupils follow the explanation and ask questions.

8. The teacher uses charts to show how pollen moves from anther to stigma.

Pupils’ Activities: Pupils observe and participate.

9. The teacher asks pupils oral questions on pollination.

Pupils’ Activities: Pupils respond to questions.

10. The teacher summarizes the lesson and evaluates pupils.

Pupils’ Activities: Pupils answer questions and participate in discussion.

CONCLUSION

To conclude the lesson for the week, the teacher revises the entire lesson and links it to the following week’s lesson.
