2 We will learn to label the parts of a plant and flower. We will learn that plants produce flowers which have male and female organs. We will learn that seeds are formed when pollen from the male organ fertilises the female organ.

4 Look at this picture. Can you label the parts of the plant?

5 The roots absorb water from the soil.

6 The stem helps to support the plant.

7 The leaves use sunlight to provide the plant with energy.

8 The flower helps the plant to reproduce.

9 This is the name for the FEMALE part of the flower. This is the name for the MALE part of the flower.

10 (female part)

11 (male part)

12 stigma pollen style anther ovary filament

13 Label the following parts on your diagram stigma style ovary anther filament pollen

14 We can label the parts of a plant and flower. We know that plants produce flowers which have male and female organs. We know that seeds are formed when pollen from the male organ fertilises the female organ.

15 We will find out more about how flowering plants reproduce. We will also find out that insects pollinate some flowers and discover how this is done!

16 REMEMBER!! Movement- towards light Reproduction- fruits and seeds Nutrition- plants make their own food Growth- seedlings to bigger plants

18 Growing plant Flowering plant Germination Pollination Dispersal of seeds Fertilisation

19 Attract insects with their sticky nectar and bright colours Male part- STAMEN (Anther and filament) Female part- CARPEL (Stigma, style and ovary)

20 The transfer of pollen onto the stigma Two ways: Insect- pollen sticks to the insect and is transferred to the female part (stigma). Wind- pollen is blown onto the stigma.

21 Joining of the pollen and the egg to make a seed. Pollen (male sex cell) travels along the style to reach the carpel where the female eggs are stored. The fertilised egg becomes a seed.

22 3 ways: Seeds are carried away from the parent plant to stop overcrowding By wind- dandelion seeds are blown away. By animals- they eat berries the seeds come out in the poo! By explosion- seed pods dry up then

23 The purpose of all flowers is to be pollinated and produce seeds

24 Partly used to protect the male and female parts of the plant Some plants use wind to blow the pollen and they have small leaves Plants which use insects to transfer the pollen usually have large petals which smell and are brightly coloured

25 The male part of the flower is called the stamen It has a long stalk called the filament At the top of the filament is the anther

26 The anther produces pollen

27 Carpels are the female parts They are made up of a stigma, style and ovary

28 It is at the top of the carpel It is sticky which helps catch pollen grains

29 The ovaries are where the eggs are made

30 Pollen grains brush against the insect, it flies to another plant, the grains rub on the stigma The grain of pollen grows a tube, which goes down the style until it reaches the ovary The male part joins with the female part to form a seed. This is called fertilisation. After fertilisation the petal drop off because they are no longer needed
