2 Making a flower Colour in the parts of the flower Female parts red
Male parts blue Stem (Tabs) green Petals – your choice. 2. Cut flower parts out and stick the tabs together in order. 3. Stick your flower into your book. 4. Match the flowers to their job. Making a flower Petals Anther Ovary Stigma Pollen Stem Where pollen is left by an insect Holds the flower up These may attract the insect to the flower and are protective The male sex cell Where pollen is made These contain the ovule or egg

3 DISSECTING A FLOWER Carefully remove one petal. Draw the petal and describe what you see. Describe what it looks like, how it was connected to the flower and how many petals the flower had. Below the petals are sepals. Draw a sepal and describe what you see. Look at the stamen (male part of the flower. How many are there? What is being produced on the anther? What are the anthers supported by? Record what you see then draw it. 4. Carefully cut through the middle of the plant This should reveal the female part of the plant. This is called the carpel. Draw what you see and describe your observations. Make sure you record where the eggs or ovum are stored in the flower.

4 Flowers are the ______ part of the plant
Carpel Filament Stamen Anther Sepal Stigma Ovary Style Petal

5 FLOWERS The male reproductive organs in a flower are called the stamen. What parts of the flower make up the stamen? Where is the male pollen produced? ****** The female reproductive organs in a flower are called the carpel. What part of the flower makes up the carpel? Where in the flower will the flowers eggs or seeds grow?

6 The pollen moves from the male anther to the female stigma
Pollination Insect Pollination The pollen moves from the male anther to the female stigma Wind Pollination Wind

7 Fertilisation Pollen sticks on sticky stigma Pollen tube grows down to ovary Pollen nucleus fuses with egg in ovary

8 Fertilisation 1. Pollen sticks on sticky stigma 2. Pollen tube grows down to ovary 3. Pollen nucleus fuses with egg in ovary

9 Fertilisation 1. Pollen sticks on sticky stigma 2. Pollen tube grows down to ovary 3. Pollen nucleus fuses with egg in ovary This is fertilisation.

10 The fertilised egg (ovum) develops into a seed.
Seed Production The fertilised egg (ovum) develops into a seed. The ovary develops into the fruit

11 Germination The seed starts to grow shoots and roots. A new plant is formed.

12 1. Pollination 4. Germination The Plant Cycle 2. Fertilisation 3. Seed production

13 Fertilisation Fertilisation Pollination Insect Pollination Pollination

15 Pollination is the movement of the pollen from one plant to another
The male sex cells are the pollen grains The male pollen grain lands on the female sticky stigma The female sex cells are the egg cells Fertilisation is when the pollen grain and egg cell nucleus join together. The pollen grain grows a pollen tube to the female ovary.
