Week 3Knowledge: Knowledge: I can independently explain the part flowers play in the

life cycle.Skill: I can draw a labelled diagram to show understanding of the life cycle of

flowering plants using scientific vocabulary.

What do you think we mean by ‘life cycle?’If the life cycle were to be a shape, what shape do you think that it would be?

2) What are the five things that a plant needs to survive?

1) What is the function of the…a)Stem – to hold the plant upright and stop it from falling over.b)Flower – contains pollen, attracts insects who spread the pollen which allows other plants to grow.c)Roots – Absorbs nutrients and water from the soild)Leaves – Absorbs sunlight which is needed to keep the plant healthy.

2) What are the five things that a plant needs to survive?To survive a plant needs soil, water, air, space and sun.

Answers:

How did you do?

When you go for your daily walk have a look at the flowers that are all around you. If you can’t go outside for a walk, have a look at these flowers below.

How do you think that they got there?

We know that plants are living things, just like us and they grow and reproduce like any other living things. They follow a cyclic process of starting a new life, growing and then coming back to the starting stage (reproducing). Plants start their life from a seed and grow up to become a mature plant.

Before we look at the life cycle of a plant – chat to someone in your house. When do you think the life cycle of a plant might be?Have a think back to when we have planted seeds in the edible garden.

1. The seed.

The life cycle begins when the seed is planted in the ground.

Have you ever planted a seed before? What did you have to do?

2. Growth

The seed needs certain things to be able to start growing – sunshine, water, air, soil and space.

3. Germination

When the seed has had enough of these things, it sprouts and starts to grow. We call this GERMINATION.

4. Reproduction

When the plant has grown, it becomes time to REPRODUCE so that new plants can grow.

5. Pollination

In order to reproduce, a plant must combine its new baby seeds with the pollen of another plant. Insects, such as bees, pick pollen up on their legs and bodies whilst collecting nectar from a flower. They then leave this pollen behind on new plants.

6. Fertilisation

When the bee has left some pollen behind, the pollen joins up with the baby seeds in the plant. When they join together, this is called FERTILISATION. The seed is now ready to become it’s own plant.

7. Seed Dispersal

Before it can grow on its own, the new seed needs to move away from the mother plant. This can happen in lots of ways – wind, by water or via birds and other animals.

The back to the beginning!

Once the seed has been ‘dispersed’ (taken away) then the cycle can start all over again!

Recap – Can you remember the order of the life cycle of a plant? Organise the stages below.

The Seed

Growth

Germination

Reproduction

Pollination

Seed dispersal

Which do you think is the most important stage? Why?

6.Fertilisation.

7. Seed Dispersal8. Life cycle starts all over again!

Task:Can you design poster that shows the life cycle of the plant?

Use this poster as an example of what yours should look like.

You must make sure every stage that we have talked about today is included on the poster and it must have an explanation.

Maybe you could plant some seeds at home and watch them grow?
