P. 144-157

Plants

Take up/release gasses through openings in their leaves called STOMATA

Stomata open and close

Water and other nutrients come from the soil via ROOTS

Animals

Take up/release gasses through a breathing system.  

This is different in different animals. Examples are Lungs and gills

Water and other nutrients come from food

P. 144-157

NUTRIENT INTAKE

Plants

One tube brings water up from the soil to the leaves

Another tube brings glucose and oxygen down from the leaves to the rest of the plant

Animals

Most animals use a blood transport system

Pump  (= heart) 

a network of tubes (= vessels)

fluid (= blood)

TRANSPORT

P. 144-157

Plants

Stomata release waste gasses

Other products are put in old leaves that fall off the plant

Animals

Breathing system releases waste gasses

Kidneys produce urine

Liver filters other waste which leaves the body through faeces

EXCRETION

P. 144-157

Plants

Move to face the sun

Sense gravity so their roots can grow down

Animals

Have senses to react to their environment

This is different depending on the animal

SENSITIVITY

P. 144-157

Plants

Flowers are used for reproduction

Animals spread pollen for plants so they can reproduce

Some plants reproduce by cloning themselves.

Animals

Male reproductive cells: Sperm cells

Female reproductive cells: Egg cells

Fertilization happens when the sperm + egg fuse together.

P. 144-157
