What happens after Pollination?

Inside a flower the female parts are… Stigma Style Ovary

This drawing shows just the female part of the flower This drawing shows just the female part of the flower. Inside the ovary there are ovules. Ovule

We already know that when a flower is pollinated, pollen grains stick to the stigma. The pollen grains grow a tube and travel down the style to join with an ovule. When an ovule and a pollen grain join together it is called fertilization.

After fertilization, the petals shrivel or fall off and the ovary grows into a fruit. The fruit on this plant is a runner bean pod. Inside the pod, the fertilized ovules turn into seeds. These seeds are called beans.

Some fruits have lots of seeds and others have just one, it all depends on how many ovules there are in the ovary of the flower. Can you name these fruits?

Which of these are fruits? All of them! The part of a plant that holds the seeds is called a fruit. Some fruits are edible (you can eat them) and some are not. Which of these fruits are not edible?

Fruits can be … huge or tiny

hard or soft

heavy or light,

rough or smooth

edible or poisonous

but all of them hold seeds … and all of them are beautiful.

Your task is to explain how fruits and seeds develop from flowers Your task is to explain how fruits and seeds develop from flowers. You will have a task sheet to help you. When you have finished, make a detailed drawing of a section through a fruit. Remember it has grown from the ovary of a flower and the seeds have developed from the fertilized ovules. Look carefully at the arrangement of the seeds. Look at the colours, shapes and patterns that you see.

Choose a piece of paper in a shade that will show off the colours of your fruit

First draw the outline of your cut fruit First draw the outline of your cut fruit. Make it larger than life so it fills your paper.

Gradually fill in the outline by drawing in the shapes you can see Gradually fill in the outline by drawing in the shapes you can see. Match the colours as closely as you can. Remember you can make your own shades by blending colours together.

Continue to draw and colour what you can see Continue to draw and colour what you can see. It doesn’t matter if it is not exactly right because every fruit is a slightly different shape.

Remember to look carefully and draw what you can see Remember to look carefully and draw what you can see. You will be using your scientific observation skills.
