LEARNING OBJECTIVES 

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

1. Identify the parts of a flower involved in pollination.

2. Explain the stages of development from flower to seed.

3. Differentiate between pollination and fertilization.

4. State the importance of pollination and fertilization in plant reproduction.

ENTRY BEHAVIOUR

Pupils have previously learned about the parts of a flower, types of pollination, agents of pollination, and the process of pollination.

This lesson builds on that knowledge by helping pupils understand the specific flower parts involved in pollination, how a flower develops into a seed and fruit after pollination, and the difference between pollination and fertilization.

INSTRUCTIONAL MATERIALS

The teacher will teach the lesson with the aid of:

1. Real flowers

2. Flower charts and diagrams

3. Flashcards

4. Pictures showing seed development

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 reproduce through flowers. During reproduction, pollen grains are transferred from the anther to the stigma in a process called pollination. After pollination, another important process called fertilization takes place.

These processes help flowers develop into fruits and seeds, which can grow into new plants.

In this lesson, pupils will learn about the parts of flowers involved in pollination, the stages of development from flower to seed, and the difference between pollination and fertilization.

PARTS OF FLOWERS INVOLVED IN POLLINATION

1. Anther – The anther is the part of the stamen that produces and contains pollen grains. It produces pollen grains needed for pollination.

2. Stigma – The stigma is the sticky top part of the pistil (carpel). It receives pollen grains during pollination.

3. Style – The style is the slender stalk that connects the stigma to the ovary. It provides a passage for pollen to travel to the ovary.

4. Ovary – The ovary is the swollen base of the pistil. It contains ovules and develops into a fruit after fertilization.

5. Ovules – Ovules are small structures found inside the ovary. They develop into seeds after fertilization.

STAGES OF DEVELOPMENT FROM FLOWER TO SEED

1. Flower blooms.

2. Pollination takes place.

3. Pollen grain reaches the stigma.

4. Fertilization occurs inside the ovary.

5. Ovules develop into seeds.

6. Ovary develops into fruit.

7. Mature seeds are formed.

DIFFERENCE BETWEEN POLLINATION AND FERTILIZATION

1. Pollination is the transfer of pollen grains from the anther to the stigma, while fertilization is the fusion of the male and female reproductive cells inside the ovary.

2. Pollination occurs before fertilization, while fertilization occurs after pollination.

3. Pollination helps pollen grains reach the female part of the flower, while fertilization leads to the formation of seeds and fruits.

4. Pollination is carried out by agents such as insects, wind, water, birds, and humans, while fertilization takes place inside the ovary of the flower.

5. Pollination does not produce seeds directly, while fertilization results in the production of seeds and fruits.

SUMMARY

In this lesson, pupils learned that the parts of a flower involved in pollination are the anther, stigma, style, ovary, and ovules.

They also learned the stages of development from flower to seed, which are:

• Flower blooms.

• Pollination takes place.

• Pollen reaches the stigma.

• Fertilization occurs.

• Ovules develop into seeds.

• Ovary develops into fruit.

• Mature seeds are formed.

Pupils further learned the difference between pollination and fertilization:

• Pollination is the transfer of pollen grains from the anther to the stigma.

• Fertilization is the fusion of male and female reproductive cells inside the ovary.

Finally, they understood that both pollination and fertilization are important processes that lead to the formation of seeds and fruits in plants.

PRESENTATION

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

1. The teacher displays a real flower or a diagram of a flower.

Pupils’ Activities: Pupils observe and identify the flower parts.

2. The teacher asks pupils to recall the meaning of pollination and the agents of pollination.

Pupils’ Activities: Pupils respond based on previous knowledge.

3. The teacher introduces the topic: Parts of Flowers Involved in Pollination, Stages of Development from Flower to Seed, and Difference Between Pollination and Fertilization.

Pupils’ Activities: Pupils repeat the topic.

4. The teacher explains the flower parts involved in pollination (anther, stigma, style, ovary, and ovules).

Pupils’ Activities: Pupils identify the parts on the chart.

5. The teacher explains the function of each flower part involved in pollination.

Pupils’ Activities: Pupils listen and take notes.

6. The teacher discusses the stages of development from flower to seed using diagrams.

Pupils’ Activities: Pupils arrange the stages in the correct order.

7. The teacher explains how fertilization occurs after pollination.

Pupils’ Activities: Pupils observe illustrations and ask questions.

8. The teacher compares pollination and fertilization using a table.

Pupils’ Activities: Pupils identify differences between the two processes.

9. The teacher asks oral questions on flower parts, pollination, and fertilization.

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

10. The teacher summarizes the lesson and evaluates pupils.

Pupils’ Activities: Pupils respond to evaluation questions and participate in the summary.
