nucleus
within the cell is a jelly-like substance called _________

mitochondira
The_________ are temporary storage compartments that sometimes store wastes
vacuoles
The _____ is a touch, rigid structure that surrounds the cell membrane and protects the cell
cell wall
The _______ trap the energy from the sun and change it into chemical energy
chloroplast

True/False The cell is the basic unit of all life
TRUE
True/False All organisms are composed of only one cell
False, some organisms are composed of billions of cells
True/False Animal cells use chloroplasts to trap the Sun’s energy
False, plant cells use chloroplasts to trap the sun’s energy
True/False Prokaryotic cells are cells that are surronded by a a cell wall
TRUE
True/False Eukaryotic cells are cells that are surrounded by a cell membrane
TRUE
True/False Some bacteria cause diseases
TRUE
True/False Viruses are non-living things
TRUE
True/False Bacteria are an example of eukaryotic cells
FALSE Animal cells and plant cells are examples of eukaryotic cells
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
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
