21

What are unicellular things?

one cell organisms

22

What are multicellular things?

organisms with more than one cell

23

What is a stimulus?

anything that causes a living thing to respond for example melting ice causes polar bears to swim

24

how do animals get energy?

by eating food and drinking water

25

how do plants get energy?

from the sun through chloroplasts

26

what are three waste products from animals?

carbon dioxide, urine and feces

27

what are the five characteristics of living things?

responding to the environment, taking in energy, growing, reproducing, and getting rid of waste

28

What is an organelle

a part in a cell in which actions and functions are done to make the cell survive

29

what organelle controls the center of the cell?

the nucleus because it controls all the cell

30

what is cellular respiration

it is how cells create energy to be used by the living organism

31

What is photosynthesis

used by plants to create their own food/oxygen, plants take light energy, carbon dioxide and water to make their food and oxygen

32

What is the difference between plants and animal cells?

plant cells have cell walls and animal cells do not, also plan cells have chloroplasts and animal cells do not
