TOPIC – REPRODUCTION IN PLANTS 

 

LEARNING AREA

1. Sexual Reproduction

2. Parts of a Flower

3. Pollination of Flower

 

PERFORMANCE OBJECTIVES

By the end of the lesson, the pupils should have attained the following objectives (cognitive, affective and psychomotor) and should be able to –

1. explain the meaning of pollination.

2. identify the different types of pollination.

3. Explain how each type of pollination occurs.

4. define the term fertilization in plants.

5. name the parts of the flower involved in fertilization.

6. identify parts of a flower that are concerned with pollination and fertilization.

7. describe stages of development from flower to fruit.

8. distinguish between pollination and fertilization.

 

ENTRY BEHAVIOUR 

The pupils can identify common flowers in the school.

 

INSTRUCTIONAL MATERIALS

The teacher will teach the lesson with the aid of:

Life flowers e.g. hibiscus, cowpea flower

Chart or diagram of a flower, agents of pollination, development from flower to fruits.

Drawing book

Pencil.

 

 

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  

LESSON 1 – INTRODUCTORY ACTIVITIES 

Teacher’s/Pupil’s Activities – Lesson reviews on Reproduction in Plants I – Parts of Flowers Primary 5 (Basic 5).

After the lesson review,

  • Take the pupils outside the class to observe the school’s flowers.
  • Call their attention on flies or insects moving from flowers to flowers. 
  • Allow two or three pupils touch the anthers of the flower and show to other.

 

Teacher’s remark – Give a great cheer for active participation on previous lesson review and outside class activities. Based on the previous assignment, discus anther and stigma.

 

MALE AND FEMALE REPRODUCTION IN PLANTS 

The male part of the flower is called anther.

The female part of the flower is called stigma.

 

 

The anther contains pollen.

The anther transfers pollen to the stigma.

This is process is called pollination.

This is how seeds or plants are produced.

MEANING OF POLLINATION 

Pollination is the process of moving pollen grains from the anther to the stigma.

Once the bee carried the pollen grains from anther to the stigma, fertilization begins. Apart from insects, pollination also take place when the winds blow.

 

AGENTS OF POLLINATION 

Pollinating agents are –

  • animals such as insects, birds, and bats
  • water
  • wind

Insects and Winds are the major types of pollination.

 

LESSON 2 – SHORT DRAMA ON POLLINATION (ANTHER, STIGMA AND BEE) 

Pupil’s role –

  • A boy acts as anther (anther contains pollen grains).
  • A girl acts as stigma.
  • A boy or girl as bee.

Teacher’s activities – Lead the guided instructions to discuss what next with anther and stigma after meeting.

 

LESSON 3 – MEANING OF FERTILIZATION 

Pollination is the transfer of pollen from Anther to Stigma of a flower.

Fertilization is the joining together of the male part of the pollen to the female ovules in the ovary.

The male part of a flower must first join with the female part.

Pollen contains the male part.

 

 

The female egg cell is inside the ovule. When the male and female parts join, we say fertilization has taken place.

 

 

 

PRESENTATION

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

1. To introduce the lesson, the teacher revises the previous lesson. Based on this, he/she asks the pupils some questions;

2. Provides flowers e.g. hibiscus to guide the pupils to identify parts of a flower.

Pupil’s Activities – Bring flowers to the class/Identify and name parts of a flower.

3. Asks pupils draw a flower on the chart and labels its parts.

Pupil’s Activities – Draw a flower and label its parts.

4. Provides flowers e.g. hibiscus to guide the pupils to identify parts of a flower.

Pupil’s Activities – Bring flowers to the class/Identify and name parts of a flower.

5. Guides the pupils to identify parts of a flower that produce fruit.

Pupil’s Activities – Identify parts of a flower that produce fruit.

6. Guides discussion on pollination.

Pupil’s Activities – Participate in the discussion on pollination/fertilization.

7 Guides discussion on the development of fruits.

Pupil’s Activities – Identify stages of development from flower to fruit.

 

CONCLUSION

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

 

NEXT LESSON

Water Cycle and Rain Formation (Primary 5)

 

LESSON EVALUATION 

Ask pupils to:

1. name and identify parts of a flower.

2. list the types of pollination.

 

 

3. list the agents of pollination.

4. list the changes that occur at different stages of development from flower to fruit

5. distinguish between pollination and fertilization in flowering plant

6. draw and label a given flower.
