Characteristics of Living Organisms Flashcards
What are the seven characteristics?
MRS GREN
Movement, Respiration, Sensitivity, Growth, Reproduction, Excretion and Nutrition
They need nutrition
Living organisms need nutrients to provide them with energy and the raw materials for growth and repair. Nutrients include things like proteins, fats and carbohydrates, as well as vitamins and minerals
They respire
Organisms release energy from their food by a process called respiration
They excrete their waste
Waste products such as carbon dioxide and urine have to be removed - removal of waste is excretion
They respond to their surroundings
Living organisms can react to changes in their surroundings
They move
Organisms move towards things like waste and food, and away from things like predators and poisons. Even plants can move a bit
They can control their internal conditions
Internal conditions include temperature and water content
They reproduce
Organisms have to produce offspring in order for their species to survive
They grow and develop
Even the smallest organisms have to grow and develop into their adult form
