Sexual Reproduction In Plants
Bayani Gaba-gaba
A flower is a plant's reproductive factory. Behind the petals that catch your eye is a precise arrangement of male and female parts whose job is to bring two sex cells together and make a seed. Learn to name those parts and say what each one does, and a cut flower stops being decoration and becomes a machine you can read.
In this lesson you will identify every part of an insect-pollinated flower, give each its function, and see how a wind-pollinated flower is built differently for a different delivery method. You will define pollination precisely, separate self-pollination from cross-pollination, and weigh up what each means for the future of a whole population.

- [Core] Identify in diagrams and images and draw the following parts of an insect-pollinated flower: sepals, petals, stamens, filaments, anthers, carpels, style, stigma, ovary and ovules
- [Core] State the functions of the structures listed in 14.1.1
- [Core] Describe pollination as the transfer of pollen grains from an anther to a stigma
- [Core] State that fertilisation occurs when a pollen nucleus fuses with a nucleus in an ovule
- [Core] Investigate and describe the environmental conditions that affect germination of seeds, limited to the requirement for: water, oxygen and a suitable temperature
- [Supplement] Identify in diagrams and images and describe the anthers and stigmas of a wind-pollinated flower
