MovementStems and leaves curve round to face the

light.

Light is needed by the leaves to make food.

Plants - Seven Processes of Life

ReproductionThe flowers of a plant contain the reproductive

organs.

The male organs (stamen) produce pollen which is transferred to the female organs (stigma) –

POLLINATION. This allows the plant to produce eggs - FERTILISATION.

When the flower dies these seeds fall from the plant, landing in the earth below.

SensitivityStems curve to face the light.

Roots grow towards water.

NutritionPlants need food. The roots take in minerals

from the soil.

The leaves then turn these mineral salts and water into food using energy from the sun.

This is called photosynthesis.

Page 7: Flowers

Plants - Seven Processes of Life

Excretion

Plant release oxygen. This is a waste product of photosynthesis.

Page 8: Flowers

Plants - Seven Processes of Life

Respiration

Plants take in Carbon dioxide (gas), They use this to make food.

Growth

Plant use the food made during photosynthesis to grow.

•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.

•We will learn to label the parts of a plant and flower.

Parts of Plant

ROOTS – take in water and mineral salts from the soil. They anchor the plant into the ground.

STEM – is like a straw. It moves water around the plant. It raises the leaves and flowers of the plant off the ground.

LEAVES – make the food for the plant. They take the water and mineral salts and use them together with sunlight and carbon-dioxide to make food.

FLOWERS – Produce seeds which the form new plants

Look at this picture.

Can you label the parts of the plant?

Page 14: Flowers

The roots absorb water from the soil.

Page 15: Flowers

The stem helps to

support the plant.

Page 16: Flowers

The leaves use sunlight

to provide the plant with energy.

The flower helps the plant to

reproduce.

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

This is the name for the MALE part of the 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.

•We can label the parts of a plant and flower.

We will also find out that insects pollinate some flowers and discover how this is done!

We will find out more about how flowering plants reproduce.
