TERMS
Calyx, corolla, sepals, petals, Androecium,
Gynoecium, Pollination, fertilisation.
FACTS
1. Sepals are green in colour
2. Sepals protect the flower in bud stage
3. Petals are brightly coloured
4. Petals help in pollination.
5. Androecium is male reproductive part of the
flower.

8. Anther produces pollen.
9. Gynoecium is the female reproductive part of
the flower.
10. Gynoecium is made up of stigma, style &
ovary.
11. Ovary bears the ovule.
12. Pollen from anther is transferred to the
stigma of the flower.
3. 13. Different agents are involved in pollination.
14. Pollen grains germinates to form pollen tube.
15. Pollen tube reaches the ovule.
16. Male gametes fuses with female gamete to
form zygote.
17. This process of fusion of gametes is called
fertilisation.
18. Fertilisation takes place in ovary.
MINOR CONCEPTS 1. Sepals are green in colour & protects the
flower in bud stage.
2. Petals are brightly coloured & attracts
insects for pollination.
3. Androecium is the male reproductive part of
the flower consisting of anther & filament.
4. Anther is bilobed & called pollen sacs which
produces pollen grain.
5. Gynoecium is the female reproductive part of
the flower consisting of stigma, style &
ovary.
6. Pollination is the process of transfer of pollen
grains from the anther into the stigma of the
flower.
7. Fertilisation is the process of fusion of male
& female gametes to form zygote.
MAJOR CONCEPT Flower is the reproductive part of plant.

PUPIL’S RESPONSE
INTRODUCTION :
- What do you all do during holidays / vacations?
- Do you visit any places?
- How many of you have visited botanical gardens?
- What attracts you to the plants?
- Who are the frequent visitors to the flowers?
- How do the insects, birds help the plants?
- Mention some life processes taking place in plants.
- Which life process is responsible for maintaining
new generation of species?
- Which are the part involved in reproduction?
- What are their functions?
- What is the team used for fusion of male gametes
with egg?
- Do you know the stage involved in fertilisation?
- Today we can discuss about the process of
fertilisation in plants.

6. PRESENTATION :
ACTIVITY – 1
Before we start discussing the process of
fertilisation we shall first discuss the parts
(androecium& gynoecium) involved in fertilisation.
A power point showing a slide of the detailed
structure of androecium& gynoecium is shown to
students. They are asked to observe the
presentation & identify the parts.
DISCUSSION POINTS
1. Identify the different reproductive parts of flower
2.Identify the different parts of androecium
3. Identify different part of gynoecium
- Androecium & Gynoecium
Anther, filament
- Stigma, style, ovary
CONSOLIDATION
Teacher concludes by explaining the structure of
androecicum & gynoecium & role of different parts
present in them.
1. Androecium& Gynoecium are reproductive
part of the flower.
2. Androecium is male reproductive part made
up stamens that consists of anther & filament.
3. Anther produces the pollen
4. Gynoecium is female reproductive part of
flower made of carpel consisting of stigma,
style & ovary.
5. Ovary is the place where fertilisation takes
place.
7. ACTIVITY – 2
A video showing the process of pollination and
fertilisation is shown to the students. They are
asked to observe & discuss various events
occurring during pollination through group
discussion.

DISCUSSION POINTS
1. What do you see in the 1ststage ?
2. What do you see in the 2ndstage ?
3. What do you call this process?
Insect visits the flower for collecting nectar.
Pollen grains from the insect gets transferred to
another flower
Pollination
CONSOLIDATION
Teacher concludes by explaining the process of
pollination.
1. In stage 1, Insect visits the flower for
collecting nectar.
2. In stage 2, Pollen grains from the insect
gets transferred to another flower
3. Pollination is the process of transfer
of pollen grains from the anther to
stigma of the flower.
DISCUSSION POINTS
1. What do you see in the 3rd stage ?
2. What do you see in the 4th stage ?
3. What do you see in the 5th stage ?
The pollen tube grows down the ovary.
The pollen fertilises the ovule
Ovules develop into seeds.
CONSOLIDATION
Teacher concludes by explaining the process of
fertilisation .
1. In stage 3, the pollen tube grows down the
ovary.
2. In stage 4, the pollen fertilizes the ovule.
3. In stage 5,ovule develop into seeds.
8. REVIEW
QUESTIONS
ACTIVITY
1. Which is the male reproductive part of flower ?
2. Explain the structure & function of Androecium.
3. Which is the female reproductive part of flower ?
4. Explain the structure & function of Gynoecium.
5. What is pollination ?
6. What are the different types of agents that help in pollination?
7. What is fertilisation ?
8. What are the stages involved in fertilisation ?
Paper cuttings containing different stages of fertilisation in flower is given to the
students and are asked to arrange them in the order of their occurrence.
FOLLOW-UP- ACTIVITY
To prepare a chart showing the male reproductive and female reproductive part of flower and describe its
role in the process of fertilisation.
