Are you familiar with MRS. NERG? Many people use these letters as a reminder of the seven scientific terms - Movement, Reproduction, Sensitivity, Nutrition, Excretion, Respiration and Growth. Anything that is alive must demonstrate all seven of these processes. Believe it or not, everything that is alive has senses of some kind - even plants. They can tell in which direction the Sun is in, and they also know the difference between up and down!

1.
Whales eat plankton and plants make their own food from sunlight. These are examples of which life process?
Reproduction
Nutrition
Movement
Sensitivity
Nutrition means food - all living organisms need food
2.
If you accidentally touch a very hot radiator and pull your hand back quickly, you are demonstrating which life process?
Sensitivity
Growth
Nutrition
Respiration
Sensitivity is how plants and animals detect changes in their surroundings
3.
Many single-celled organisms grow and then divide into two cells. What is this is an example of?
Excretion
Reproduction
Respiration
Nutrition
The cell makes an exact copy of itself
4.
The food that animals eat cannot be used directly by cells. What is the process of turning food into energy called?
Excretion
Nutrition
Respiration
Growth
Because oxygen is essential for this life process, people often refer to breathing as 'respiration'
5.
Food provides energy for movement and other life processes. What else does food allow a living organism to do?
Rest
Grow
Camouflage itself
Become a predator
The body uses food to make itself bigger
6.
Which of the following demonstrates sensitivity in plants?
A plant producing food through photosynthesis
A sycamore seed falling far from the parent tree
A spindly tree in a dark forest growing quickly towards the light
A weeping willow crying at sad films
Plants respond to heat, light, moisture and other stimuli
7.
Sunflowers were given their name because they turn to face the Sun. This is an example of which life process?
Respiration
Growth
Excretion
Movement
All living organisms move. It can be hard to observe the movements of plants, but the sunflower makes a good example because it is easier to observe than most other plants
8.
Which of the following is true?
Only animals share the seven life processes
Only plants share the seven life processes
Plants and animals share all seven life processes
Plants and animals only share four life processes
All living organisms, which includes all plants and animals, share the seven life processes
9.
Which is not an example of reproduction?
A dandelion produces and disperses its seeds
A cat has kittens
A large rock is crushed into thousands of small pieces of gravel
A strawberry plant runner grows a new plantlet
Reproduction is when living organisms produce young
10.
Plants need to get rid of oxygen and animals need to get rid of carbon dioxide. What is this process called?
Respiration
Growth
Excretion
Reproduction
Excretion, or elimination, is the removal of all waste products
