What function do roots perform for the plant?
They take in nutrients from the soil.
They don't do anything.
They take in energy from the sun.
What is the smallest unit that can perform all functions necessary for life?
Atom
Cell
Prokaryotic Cell
Eukaryotic Cell
What substance must animal cells take in from the environment to maintain homeostasis?
Carbon Dioxide

How is cellular respiration different from photosynthesis?
(P = Photosynthesis) (CR = Cellular Respiration)
P produces carbon dioxide. CR produces oxygen.
P produces glucose. CR produces oxygen.
P produces oxygen. CR produces glucose.
P produces oxygen. CR produces carbon dioxide.
True or False:
Homeostasis is the maintenance of a stable internal condition.
True
False
What is cellular respiration?
The process by which sugar is broken down to release energy.
The process by which cells produce sugar.
It is the same as photosynthesis.
True or False:
The cell membrane separates the inside of the cell from the environment.
True
False
True or False:
The endoplasmic reticulum is a system of folded membranes.
True
False
How does oxygen affect the process of cellular respiration?
Oxygen is the product of cellular respiration.
Oxygen and glucose combine and they make energy in the form of PTA.
Oxygen and glucose combine and they make energy in the form of ATP.
Oxygen is not involved in cellular respiration.
What do animals do with the carbon dioxide produced in their cells during cellular respiration?
They use it.
They breathe it out.
Carbon dioxide is not produced during cellular respiration.
Trick Question!!!!!
True or False:
Oxygen is one product of photosynthesis.
True
False
What happens to glucose inside a cell during cellular respiration?
The cell uses glucose for energy.
The glucose is pushed aside for later use.
The cell uses oxygen to break down glucose.
The cell uses glucose to break down oxygen.
What does the cell use to break down glucose?
Carbon dioxide
Oxygen
Lipids
Amino acid
