What are unicellular things?
one cell organisms
What are multicellular things?
organisms with more than one cell
What is a stimulus?
anything that causes a living thing to respond for example melting ice causes polar bears to swim
how do animals get energy?
by eating food and drinking water
how do plants get energy?
from the sun through chloroplasts
what are three waste products from animals?
carbon dioxide, urine and feces
what are the five characteristics of living things?
responding to the environment, taking in energy, growing, reproducing, and getting rid of waste
What is an organelle
a part in a cell in which actions and functions are done to make the cell survive
what organelle controls the center of the cell?
the nucleus because it controls all the cell
what is cellular respiration
it is how cells create energy to be used by the living organism
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
