CONTENT: (a) Crop plant forms ;(i) Parts of Flowering Plant and Their Functions.
Sub-topic 1:
A flowering plant is made up of two parts
The Flower
The flower contains the reproductive parts of the plant. The male reproductive part of the flower is called the stamen. Each stamen is made up of an anther containing pollen grains and a filament. The anther is attached to the flower through the filament.
The female reproductive parts of the flower are the ovary, style, and stigma.
The ovary contains small undeveloped seeds called ovules.
Functions of the flower
The Fruit and seed
Fruit and seed are formed through pollination and fertilization.
Pollination is the transfer of pollen grains from the anther of a flower to the stigma of the same flower (self-pollination) or of another flower of the same or related species, either by insects or by the wind. While fertilization is the fusion (joining together) of male and female gametes.
After successful pollination and fertilization, the ovary will develop into a fruit and the ovules will develop into a seed.
