Movement
Animals can move from place to place.
Plants do not move from place to place they move when they grow or when a flower opens or closes its petals
Respiration
Respiration is the way living things get energy. They take on oxygen and mix it with food to get energy.
Sensitivity
Is the ablity to react to changes in the environment. Animals will run away from danger. A plant will grow towards life
Feeding
Animals do not make there own food they get there food from eating other plants and animals . Plats make there own food.
Photosynthesis
They way in which plants make food is called photosynthesis.
To make food they need a green dye called chlorophyll this is why most plants are green
Excretion
Is the removal of waste made in the body from the body. Animals excreste carbon dioxide water urea and salts
Reproduction
Is being able to make new individuals of the same kind eg babies new plants puppy’s
Growth
Results from cell division
Cell membrane
Very thin layer surrounded the cell hold cell contents in place and controls what passes into and out of the cells
Cytoplasm
The very watery liquid found between the nucleus and the cell membrane
Nucleus
Is normally round. acts as the control centre of the cell. It has the dna.
Mitochondria
Supply energy to the cell
