Original PromptEvery living thing — from a single bacterium to a giant tree — carries out the same seven life processes to survive. Scientists remember them using the mnemonic MRS GREN.
Movement
Respiration — releasing energy from food
Sensitivity — responding to surroundings
Growth
Reproduction
Excretion — getting rid of waste
Nutrition — taking in food and nutrients
Both plants and animals show all seven characteristics, even though they can look very different in each.

This learning resource focuses on the characteristics of life, known as MRS GREN, which includes Movement, Respiration, Sensitivity, Growth, Reproduction, Excretion, and Nutrition. Students are tasked with defining these life processes, identifying key cell structures, and differentiating between plant and animal cells through a comparative analysis. The worksheet also includes sections for students to self-reflect on their understanding and confidence in these concepts. Additionally, there are questions that challenge students to apply their knowledge about cell organelles and their functions. The ultimate goal is to deepen the understanding of what constitutes life and the fundamental structures that support biological functions.
