Life Processes Vocabulary
The process by which organisms become bigger and stronger is growth.

Life Processes Vocabulary

In KS2 Science, pupils discover life processes. These include activities like breathing, feeding, and growing that show whether something is alive or not.

Fascinating Fact:

The seven life processes are movement, respiration, sensitivity, nutrition, excretion, reproduction, and growth.

In KS2 Science, children use the term MRS GREN to remember the seven life processes. These processes are vital signs that distinguish living organisms from non-living things.

  • Nutrition: The way living things take in and use food for energy and growth.
  • Reproduction: The process by which living things make new individuals of the same kind.
  • Growth: The increase in size and complexity that living things show during their lifetime.
What does MRS GREN stand for in KS2 Science?

MRS GREN stands for Movement, Respiration, Sensitivity, Growth, Reproduction, Excretion, and Nutrition. These are the seven life processes.

Why do we learn about life processes in KS2?

Life processes are taught in KS2 to help pupils understand what makes something alive and how organisms survive, grow, and reproduce.

How can you tell if something is living or non-living?

If something carries out the seven life processes, it is considered living. If it does not, it is non-living.

1 .
Which life process stops at death?
Respiration
Growth
Nutrition
All of the above
Death is when all life processes stop - all living organisms die eventually
2 .
Which life process is the ability to change place or position?
Growth
Reproduction
Movement
Respiration
Animals use their bodies to move, while plants move by growing or turning towards the Sun
3 .
What is the process by which organisms become bigger and stronger?
Exercise
Nutrition
Movement
Growth
All living organisms grow
4 .
Which life process is the ability to respond to a stimulus?
Movement
Sensitivity
Respiration
Reproduction
Stimuli (plural of stimulus) include light, heat, sound, touch, taste and smell - all living organisms are sensitive or responsive to stimuli
5 .
What is the life process by which food is transformed into the energy living things need?
Reproduction
Respiration
Digestion
Absorption
Food molecules are broken down to release energy in a process called respiration. Because our bodies require oxygen for this process, human respiration also includes breathing oxygen in and carbon dioxide out
6 .
What is the life process by which an organism rids itself of waste products?
Respiration
Feeding
Circulation
Excretion
All living things must get rid of the useless or toxic byproducts of chemical processes - this is called excretion
7 .
Which life process uses other sources to replace the energy needed to maintain life?
Reproduction
Nutrition
Growth
Sensitivity
This is another way of saying that living organisms require food, which can only be found from outside themselves (even in the case of plants, which need the Sun in order to make food)
8 .
What is the life process by which living organisms obtain food?
Nutrition
Hunting
Respiration
Growth
Plants create their own food from the Sun's energy in a process called photosynthesis. Animal nutrition includes feeding and digestion
9 .
Which life process is the ability of living organisms to produce more of the same species?
Growth
Respiration
Reproduction
Creation
Organisms produce offspring to keep the species going after their death
10 .
What is the process of cell division (fission) or cloning to create new individuals in a species?
Sensitivity
Respiration
Reproduction
Growth
This definition refers specifically to the method of reproduction seen in some plants and single-cell organisms
