Ch. 2: Flower and Fruit
From flower to fruit to seed: structure of a flower, pollination (self & cross), agents (bee, wind, water, bird), fertilisation, fruit types and seed dispersal — with full interactive animations.
Parts and four whorls of a flower
Androecium and gynoecium
Self and cross pollination
Agents of pollination
Fertilisation and fruit formation
Types of fruits and seed dispersal
Science tip: use Visual and Concept modes — diagrams and particle models help you “see” the idea, not only read it.
# Flower & Fruit — Super Simple
A **flower** is the plant’s **baby-making factory**.
A **fruit** is what the flower becomes after success — with **seeds** inside.
### Story in one line
**Flower → pollination → fertilisation → fruit → seed → new plant**
### Four layers of a flower (outside → in)
1. **Sepals** (calyx) — green protectors of the bud
2. **Petals** (corolla) — colour & perfume to call bees
3. **Stamens** (androecium) — **male** (pollen)
4. **Pistil** (gynoecium) — **female** (egg in ovary)
### Must-know words
- **Pollination** — pollen travels from anther to stigma
- **Fertilisation** — male cell + female cell join → zygote
- **Ovary becomes fruit** · **Ovule becomes seed**

Topics in this chapter
-
What is a flower?
Reproductive shoot from floral bud. Attracts pollinators. Makes gametes.…
-
Parts and four whorls
Pedicel, thalamus, calyx, corolla, androecium, gynoecium.…
-
Androecium (male)
Stamen = anther + filament. Pollen carries male gametes.…
-
Gynoecium (female)
Stigma, style, ovary, ovules with egg cell.…
-
Pollination
Self and cross. Transfer of pollen anther → stigma.…
-
Agents of pollination
Insects, wind, water, birds — adaptations of flowers.…
-
Fertilisation to fruit
Zygote forms; ovary → fruit; ovule → seed.…
-
Types of fruits
Berry, drupe, pome. True vs false fruit. Pericarp layers.…
-
Seed dispersal
Wind, water, animals, explosion. Fruit protects and spreads seeds.…
