Living organisms need nutrients to provide them with energy ant the raw materials for growth and repair. Nutrients include things like proteins, fats and carbohydrates, as well as vitamins and minerals.

Waste products such as carbon dioxide and urine are removed from the body - This removal is called excretion .

Organisms that are alive can react to change in their environment/surroundings

Organisms move toward things like water and food, and away from things that threaten them ( some plants can move a bit )

Organisms have to produce offspring in order for the species to survive

Living organisms are made up of cells - these are like tiny building blocks. Some organisms are multi cellular - they contain lots of cells, which need some form of organisation. Some organisations consists of a single cell.

2. Organelles are tiny structures within cells. You can only see them using a powerful microscope.

Eukaryotic cells are complex, and include all animal and plant cells

An organelles which contains the genetic material that controls the cells activities. It is surrounded by its own membrane.

This membrane forms the outer surface of the cell and controls the substances that go in and out.

A gel-like substance where most of the cells chemical reactions happen. It contains enzymes which control these reactions

Small organelles where most of the reactions for aerobic respiration take place. Respiration transfers energy that the cell needs to work
