Plant reproduction
In this unit we are going to learn about how flowering and non-flowering plants reproduce. The reproductive organs of most plants are in the flowers. It is in this part of the plant that the two reproductive processes occur: pollination and fertilisation. After fertilisation, the flowers develop into fruit, containing seeds. These seeds germinate and grow gradually into a new plant.

Some plant species reproduce asexually, but most plants reproduce sexually. A pollen grain fertilises the egg cell inside the ovule. The sexual organs of spermatophytes (flowering plants) are in the flowers. [...]
-
Pollination Sexual reproduction in plants occurs when a spermatozoid meets an ovule. For this to happen, the pollen grains need to travel from the stamens to the pistil. This process of transferring pollen grains is called pollination. [...]
-
The fruit As a seed develops, the pistil changes and grows, the petals fall off, and it becomes a fruit. Fruits have many different forms: Some are fleshy like peaches, pears and oranges. [...]
-
Asexual reproduction in flowering plants Some flowering plants can produce descendents from a single parent plant without the help of another individual. This type of reproduction is called asexual reproduction. [...]
