  1. Life Processes Let’s look at living things

  2. Living Things • There are many different types of living things and they all look very different when compared to each other. • But all living things have seven things in common. We call these life processes. You need all seven to be alive.

  3. The seven life processes are…… • movement • reproduction • sensitivity • nutrition • excretion • respiration • growth Let’s look at these in more detail

  4. 1. Movement • Animals move around using their whole bodies to get from one place to another. • Plants move by turning towards the sun. Their roots move deeper into the soil

  5. 2. Reproduction • Animals have babies: some lay eggs and the babies hatch out of these. • Plants produce seeds and new plants grow from them

  6. 3. Sensitivity • All living things respond to changes in their environment and react to them. • eg. People react to changes in the weather and temperature and make changes to their behaviour. • eg. Flowers react to the light and close when it is dark.

  7. 4. Nutrition • Food is used by living things to give them the energy to do their usual things. • Green plants use sunlight to make their energy. • Animals eat plants; like leaves, fruits and vegetables; or other animals.

  8. 5. Excretion • Waste substances must be removed from the body. Both plants and animals need to get rid of water and other waste products. • We do this when we go to the toilet.

  9. 6. Respiration • All living things use the oxygen in the air to convert food into energy.

  10. 7. Growth • All living things grow, even if it is just a small amount. • Babies and young animals become adults. • Seeds grow into plants.
