- Order. Organisms are highly organized, coordinated structures that consist of one or more cells. Even very simple, single-celled organisms are remarkably complex: inside each cell, atoms make up molecules; these in turn make up cell organelles and other cellular inclusions.
- Sensitivity or Response to Stimuli. Organisms respond to diverse stimuli. For example, plants can bend toward a source of light, climb on fences and walls, or respond to touch (Figure 2).
- Reproduction. Single-celled organisms reproduce by first duplicating their DNA, and then dividing it equally as the cell prepares to divide to form two new cells.
- Growth and Development. All living things increase in size and/or change over their lifespan. For example, a human grows from a baby into an adult and goes through developmental processes such as puberty.
An easy way to remember these characteristics is to use the acronym Mrs Gren (or Mrs Nerg): Movement – they move or change position. Respiration – they get energy from their food. Sensitivity – they respond to stimuli such as light, sound, temperature. Growth – they grow and develop.
