Set Induction (Classroom Story Prompt)
The teacher walks in holding a red hibiscus flower and a ripe mango.

“Can plants have babies without seeds?”
Let’s find out together!
Lesson Content
1. Pollination
Definition: Pollination is the transfer of pollen grains from the anther (male part) to the stigma (female part) of a flower.
Types of Pollination:
-
Self-pollination: When pollen moves from the anther to the stigma of the same flower or another flower on the same plant.
-
Cross-pollination: When pollen is transferred to the stigma of a flower on a different plant of the same species.
Agents of Pollination:
-
Insects (e.g. bees, butterflies)
-
Wind
-
Water
-
Birds and bats
2. Fertilization
Definition: Fertilization is the process where the male sex cell (from the pollen) fuses with the female egg cell (ovule) to form a zygote.
Process of Fertilization:
-
Pollen lands on stigma
-
Pollen tube grows down into ovary
-
Male cell travels down and meets ovule
-
Fertilization occurs and forms a zygote
-
Zygote becomes seed, and ovary becomes fruit
3. Budding
Definition: Budding is a form of asexual reproduction where a new organism develops from a bud on the parent’s body.
Examples:
-
Hydra: A small hydra grows on the parent and falls off to live on its own.
-
Yeast: The new bud forms and separates from the parent cell.
Key Idea: No male or female cell needed; only one parent.
4. Coloration
Definition: Coloration is the arrangement or pattern of colors on plants and animals.
Functions of Coloration:
-
Camouflage: Helps animals hide from enemies (e.g. chameleon)
-
Warning Colour: Shows danger (e.g. red on some poisonous frogs)
-
Attraction: Bright flower colors attract pollinators
-
Mating: Male peacocks show colourful feathers to attract females

✅ Lesson Summary (Key Points to Remember)
-
Pollination is how pollen moves to the stigma; fertilization is when the male cell joins the female ovule.
-
Budding is asexual reproduction from one parent.
-
Coloration helps in hiding, mating, or warning predators.

Learning Objectives
By the end of this lesson, learners should be able to:

What Is Pollination?
Definition
Pollination is the movement of pollen grains from the anther (male part) to the stigma (female part) of a flower.
Types of Pollination
-
Self-Pollination: Pollen is transferred within the same flower or between flowers on the same plant.
-
Cross-Pollination: Pollen moves from one plant to another of the same species.
Agents of Pollination
-
Insects (e.g., bees, butterflies)
-
Wind
-
Water
-
Birds or bats
What Is Fertilization in Plants?
Definition
Fertilization occurs when the male sex cell (in pollen) unites with the female sex cell (ovule) in the ovary to form a zygote.
Steps in Fertilization
-
Pollen lands on the stigma
-
Pollen tube grows down the style
-
Male nucleus moves into the ovule
-
Fertilization takes place
-
Zygote becomes a seed; ovary becomes a fruit
What Is Budding?
Definition
Budding is a form of asexual reproduction where a new organism develops as an outgrowth (bud) from the parent.
Examples of Budding
-
Yeast
-
Hydra
Key Features
-
Involves one parent only
-
No fusion of male and female cells
-
Bud may remain attached or break off
What Is Coloration?
Definition
Coloration refers to the pattern or arrangement of colours found on the bodies of animals and plants.
Functions of Coloration
-
Camouflage: Blending into the environment (e.g., chameleon)
-
Warning: Bright colours to signal danger (e.g., red frogs)
-
Attraction: Bright flowers attract pollinators
-
Mating Display: Male animals use colours to attract mates
