There are seven processes that are carried out by all species of animals and plants
|
Life processes |
What it means |
| Movement | Going from one place to another.
Animals usually move their whole body from one place to another. Leaves turn towards the light. Roots grow down into the soil. |
|
Reproduction |
Producing new plants or animals.
Animals have babies. New plants grow from seeds. |
|
Sensitivity |
How things react and respond to what is happening around them eg plants
turning and moving towards the light or
your mouth watering when you smell something good to eat. |
|
Nutrition |
Taking in food. Food is needed to supply energy
Green plants can make their own food using sunlight, carbon dioxide and water. Animals eat plants or other animals. |
|
Excretion |
Getting rid of waste substances.
eg Plants and animals excrete (get rid of) carbon dioxide. |
|
Respiration |
Making energy to keep you active.
Plants and animals use oxygen from the air to help turn food into energy. We need energy for our muscles. |
|
Growth |
Getting bigger.
Seedlings grow into bigger plants. babies grow into adults |
Respiration:
Respiration is a chemical reaction that provides all life with energy
All living organisms, animals and plants, carry out respiration
Normal (aerobic) respiration requires oxygen and glucose (a kind of sugar)
The sugar reacts with the oxygen making carbon dioxide and water as waste products and releasing energy.
Word equation: sugar + oxygen -----> carbon
dioxide + water + energy
Respiration is the exact reverse of photosynthesis.
Learn them both carefully but DO NOT MUDDLE THEM UP
