Plant Reproduction
Like animals, plants reproduce.
Flowers grow when the plant is ready to reproduce.
The stages of plant reproduction are: - pollination, - fertilisation and - fruiting.

Plant Reproduction
A bee visits flowers to collect nectar to make honey. Nectar is a sweet liquid.
The flowers make nectar to attract insects and birds.

Plant Reproduction
Pollen from the anthers stick to the bee. The bee carries the pollen to other flowers.

Plant Reproduction
The bee brushes pollen onto the stigma. This is called pollination.

Topic 3
Plant Reproduction
The pollen fertilises the ovules. The ovary becomes a fruit, which protects
the seeds. Some fruits are soft and juicy; others are
hard and tough.
