What are the parts of a plant?
The organisation of plants
stem: it supports and transports water, minerals and nutrients throughout the plant.
leaves: they make food for the plant.

What are the parts of a plant?
The organisation of plants
stem: it supports and transports water, minerals and nutrients throughout the plant.
leaves: they make food for the plant.
roots: they absorb water and nutrients from the soil. They have root hairs that increase the area of contact.

What are the life processes in animals?
All living things carry out the basic life processes of interaction, nutrition and reproduction but they do these in different ways.

Nutrition
All living things take in
essential nutrients from the
environment.
These nutrients give them
energy and enable them to
grow and develop.

Interaction
All living things detect
information in their environment.
Then they react to this
information in different ways.
In vertebrates, interaction is
carried out using the locomotor
and nervous systems.

Reproduction
Plants reproduce in different ways:
• Seed plants: produce seeds.
• Non-seed plants: don’t produce seeds.
They reproduce by producing special cells
called spores, or by producing capsules.
They are transported by the wind, when
they fall onto the ground and grow into a
new plant.
