  • Topic: Reproduction In Plants: Fertilization
  • Content: Fertilization

Performance Objectives:

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

  • Cognitive domain: Describe the process of fertilization in plants.
  • Affective domain: Appreciate the role of fertilization in the reproductive process of plants.
  • Psychomotor domain: Identify and demonstrate the steps in the fertilization process using a diagram or model.
  • Social domain: Collaborate with peers to discuss the importance of fertilization in the plant lifecycle.

Reference Materials:

The following resources were used in planning this lesson:


Instructional Materials:

The teacher will teach this lesson with the aid of:

  • Diagrams of the fertilization process
  • A model of a flower (or real flower samples)
  • Chart showing stages of fertilization

Rationale for the Lesson:

Understanding fertilization is crucial because it explains how plants reproduce and how seeds are formed. This process is essential for the growth of new plants, which provides us with food, medicine, and many other resources. Fertilization in plants ensures the continuation of plant species, making it a significant topic in Basic Science.


Prerequisite/Previous Knowledge:

Pupils are expected to have a basic understanding of pollination, which was taught in the previous lesson. They should be familiar with the different parts of a flower, including the stamen, pistil, and ovary, as these are involved in the fertilization process.


Instructional Procedures:

To deliver this lesson, the teacher will adopt the following steps:

Content DevelopmentTimeTeaching MethodTeaching StrategyTeacher’s ActivityPupils’ ActivityLearning Point
Step 1: Introduction5 minutesSet inductionQuestioning, visual aidGreet the pupils and ask: “Do you know how plants make new plants?” Show a diagram of a flower and ask pupils to identify parts.Pupils will respond and identify parts of the flower.Fertilization is the process by which plants reproduce.
Step 2: Explanation of Fertilization10 minutesExplanationVisual presentationExplain the meaning of fertilization and its importance in plant reproduction. Use the diagram to show where fertilization occurs.Pupils will listen and take notes on fertilization.Fertilization involves the joining of the male and female gametes.
Step 3: Steps in Fertilization10 minutesDemonstrationStep-by-step explanationDescribe and demonstrate the steps of fertilization (pollen grain reaching the stigma, travel to ovary, fertilization).Pupils will follow along, asking questions if needed.The steps of fertilization include pollen landing on the stigma and merging with the ovule.
Step 4: Pupils’ Participation5 minutesGroup discussionCollaboration, modelingAsk pupils to work in groups to draw and label a fertilization diagram.Pupils will draw and label the diagram in groups.Group work helps reinforce the understanding of the process.
Step 5: Note Taking3 minutesIndividual workNote takingGuide pupils in copying the lesson content on fertilization.Pupils will write down the note in their notebooks.Writing down the information helps pupils retain key details.
Step 6: Evaluation5 minutesOral questioningQuestioningAsk the pupils questions based on the lesson, focusing on key concepts.Pupils will answer the questions orally.Evaluation ensures comprehension and reinforces learning.
Step 7: Conclusion2 minutesRecap and closureSummarySummarize the main points of the lesson and clarify any misunderstandings.Pupils will ask for clarification if necessary.Fertilization is a vital process in plant reproduction.

Lesson Content:

Reproduction In Plants: Fertilization

Fertilization in plants is the process where the male gamete (pollen) and the female gamete (ovule) come together to form a seed. This process allows plants to produce new plants and ensure the survival of their species.

The Process of Fertilization:

  • The process begins when a pollen grain from the male part (anther) of a flower lands on the female part (stigma).
  • The pollen grain travels down the style to the ovary, where it meets the ovule.
  • The male gamete then fuses with the female gamete (ovule), resulting in fertilization.
  • The fertilized ovule develops into a seed, which can grow into a new plant.

Steps in Fertilization:

  • Step 1: Pollen grain lands on the stigma.
  • Step 2: The pollen tube grows down the style to reach the ovary.
  • Step 3: The sperm cell from the pollen fuses with the egg cell in the ovule.
  • Step 4: The fertilized egg becomes a seed, ready to grow into a new plant.

    Lesson Evaluation:
    To evaluate the learning, the teacher asks pupils to:

    1. What is fertilization in plants?
    2. Describe the steps involved in fertilization.
    3. What role does pollen play in fertilization?
    4. Why is fertilization important for plants?
    5. How does fertilization result in the creation of new plants?

    Note for teachers using this lesson plan:
    This lesson requires active participation from pupils, especially when discussing the steps in fertilization. Use the flower diagrams to make the concept more visual and concrete. Encourage students to ask questions during the group activity to enhance learning. Review the content regularly to ensure students understand each stage of the process. Happy teaching!
