What are the seven life processes remembered by MRS GREN?
Movement, Respiration, Sensitivity, Growth, Reproduction, Excretion, Nutrition.
What does Movement mean in life processes?
All living things can move by themselves.
Give an example of movement in plants.
Growing towards light (phototropism).
What does Respiration mean?
The release of energy from food.
Which gas do most organisms need for respiration?
Oxygen.
What does Sensitivity mean in life processes?
Detecting and responding to changes in the environment (stimuli).
Give an example of sensitivity in animals.
Moving away from danger or towards food.
Give an example of sensitivity in plants.
Responding to light or gravity.
What does Growth mean in life processes?
All living things grow and develop.
How do animals usually grow?
By increasing in size and mass.
How do plants usually grow?
By cell division, often at their tips.
What does Reproduction mean?
Making more of the same kind of organism.
Name two types of reproduction.
Sexual reproduction and asexual reproduction.
What does Excretion mean in life processes?
Removing waste products made in cells.
Give an example of excretion in humans.
Breathing out carbon dioxide or producing urine.
What does Nutrition mean in life processes?
Taking in and using food for energy and growth.
How do animals get their nutrition?
By eating other plants or animals.
How do plants get their nutrition?
By making food in photosynthesis.
What is the importance of the 7 life processes?
They show the difference between living and non-living things.
Which life process provides the energy needed for all the others?
Respiration.
