Biological Science Biology is the study of living organisms

Living organisms What is a living organism? A living organism is a animal, plant or singlecelled life form. How can we decide if something is living or non living?

Living organisms Watch video titled “living and non living things” The video mentions 7 characteristics of living things. In class we will be learning about 8 characteristics with slightly different terminology

Living organisms – If something is alive it will carry out all of the eight characteristics. – Movement – Respiration – Stimulus – Cells – Growth – Reproduction – Excretion – Nutrition

How can we remember these? S Movement Respiration Stimulus C Cells G Growth Reproduction Excretion Nutrition M R R E N

MRS C GREN Living organisms are able to perform all of MRS C GREN and non living cannot (You will need to remember what all the letters of MRS C GREN stand for!!)

Characteristics of Living Things – M is for movement – Animals move to find food, shelter or a mate. – Plants do not move in the same way as animals but move towards sunlight.

Characteristics of Living Things – R is for respiration – Respiration is the release of energy from food.

Characteristics of Living Things – S is for stimulus – Stimulus is the detection and response to changes in the environment

Characteristics of Living Things – C is for cells. – All living things are composed of one or more cells

Characteristics of Living Things – G is for growth – Growth is the change in the size of an organism over time

Characteristics of Living Things – R is for reproduction – The ability of living organisms to make offspring which are similar to the parents.

Characteristics of Living Things – E is for excretion – The removal of this waste is called excretion.

Characteristics of Living Things – N is for nutrition – Getting food inside an organism – Plants make their own food by the process of photosynthesis.

Why aren’t fluffy toys alive? Fluffy toys often look like real animals

Aliens land on Earth and watch things carefully to tell whether they are alive or not. Would an alien think this car is alive?
