Living Things!

1.Cells are the basic unit of life.

1. Living things are made of cells.  Some are unicellular (live without any other cells) (1 cell)  Some are multi- cellular (1+ cells)  Cells are the basic unit of life

2. Living things exchange gases!  All animals use Oxygen and change it to Carbon Dioxide (Respiration)  All plants use Carbon Dioxide and change it to Oxygen (Photosynthesis)

3. Living things use energy!  All living things need gas, water and food to live.  Food provides nutrients like fats, proteins and carbohydrates.  Use nutrients and energy for growth, repair and other activities

Using Energy  Animals are heterotrophs (Eat others for Energy)  Plants are autotrophs (Make their own energy)

4. Living things grow!  Growth can mean an increase in the size of cells  Growth can also mean the creation of new cells (repairing the body)  Regeneration (ie Starfish)  Dropping body parts

5. Living things reproduce!  Produce offspring  Different ways  Budding (sea aneomes)  Live young  Regeneration  Eggs  Seeds and spores

6.Living things respond to stimuli.  Stimuli causes reactions  React to touch, heat, temperature and sound  Movement does not always mean a response (leaf in the wind)  Behaviour is directed towards minimal injury, acquiring food and reproducing.
