MRS GREN

Movement Respiration Sensitivity Growth Reproduction Excretion Nutrition

Helps you remember the seven characteristics of living things.

Quick self-quiz

Tap each word to check what it stands for.

When to use it

Use it to check whether something qualifies as a living organism by verifying it performs all seven life processes.

Example

A plant shows all seven: it grows toward light (movement, sensitivity), photosynthesizes (nutrition), releases oxygen (excretion), and reproduces via seeds.

Common mistake

Thinking movement only means walking. Plants and fungi also move, just slowly, through growth responses.
