Reproductive parts of flowering plants Flowers usually have male and female parts. The male part of the flower is made up of 2 parts they are anther and the filament. the female part of the flower is made up of three parts they are the stigma, the style and the ovary.
Pollination Pollination is the process by which pollen grains are transferred from the anther to the stigma. Some animals such as insects ,birds help in pollination. Wind can also help in pollination to transfer pollen grains.
Fertilisation Each pollen grain contains 2 male sex cells, which travel through the pollen tube to the female sex cell held in the ovule. After fertilisation ,the ovule develops into a seed and the ovary forms a fruit.
Dispersing seeds Seeds need to dispersed away from the adult plants. The adult plants needs air, water ,sunlight, and mineral salts to survive. Seeds can be dispersed by wind,water,animals or by splitting open.
Germination If seed is not dead ,it will germinate when it gets enough water , air and warmth A seed does not need light to germinate. When a root grows out of a seed ,it shows that the seed has germinated
Quiz time ! Name them. What is the four stages in plants? The stages are pollination, germination, fertilisation and dispersal. What is fertilisation? Fertilisation is the process in which a male sex cell fuses with the female sex cell. How many ways are there in dispersing seed name them? There are four ways. They are animals,wind,water and spilitting open What do you need for germination? It need water ,air and warmth.
