π± Plant Reproduction πΈ
How do plants create new plants? Let's explore the fascinating world of flowers, fruits, seeds, and vegetative reproduction!
πΊ Part A: The Flower
A flower is the reproductive structure of flowering plants (called angiosperms). It contains the parts needed to produce seeds and, eventually, new plants.
The Four Main Parts of a Flower
Flower parts are arranged in circular layers called whorls. From outside to inside, they are:
1. Sepals
π
The outermost parts that enclose and protect the flower bud before it opens. Together, all the sepals form the calyx.
2. Petals
πΈ
Brightly colored parts that attract pollinators like bees, butterflies, and birds. Together, all petals form the corolla.
3. Stamen β
π΅
The male reproductive part. It has two components:
Anther β produces pollen
Filament β holds the anther up
4. Pistil / Carpel β
π‘
The female part, shaped like a bowling pin:
Stigma β sticky top catches pollen
Style β connects stigma to ovary
Ovary β contains ovules (eggs)

β Complete Flower
Has all four main parts: sepals, petals, stamens, and pistil. Examples: roses, lilies.
β Perfect Flower
Has both stamen and pistil (the essential reproductive parts), even if it lacks petals or sepals.
π Pollination
Pollination is the transfer of pollen grains from the anther (male) to the stigma (female). There are two main types:
