How are Carbon dioxide and water molecules recycled in photosynthesis?
a) They are copied, or replicated.
b) They are oxidized.
c) They are broken up and put back together to form Glucose.
d) They are broken up and put back together to form ATP.

What happens to glucose molecules during respiration?
a) They are oxidized.
b) They are broken up and put back together to form Glucose.
c) They are broken up and put back together to form ATP.
d) They are copied, or replicated.

How is energy converted in photosynthesis?
a) Stem cells become new types of cells
b) ATP is used to make new cells
c) Chemical bonds are broken, releasing energy used to make another form of chemical energy (ATP).
d) Energy from light is used to produce (potential) chemical energy, or sugar.

Why do nearly all living things rely on the conversion of solar energy?
a) they need Carbon dioxide, which is made in photosynthesis.
b) they need food (Glucose) that is made in photosynthesis.
c) They are all heterotrophs
d) They are all autotrophs

This process is required for plants, animals, and other organisms to grow.
a) Cell Merging
b) Cell Division
c) Experimenting
d) Modeling

How are fire and cellular respiration alike?
a) There are no similarities.
b) Both require Carbon dioxide and Water
c) Both produce oxygen and fuel
d) Both require oxygen and fuel

What is differentiation?
a) The different ways energy is converted
b) When cells are lost
c) When cells change to become new, different types of cells.
d) Producing identical cells

What happens to DNA during the cell cycle?
a) DNA is copied and distributed to 2 new daughter cells
b) DNA is not important in the cell cycle
c) DNA is copied twice to make 4 identical cells
d) DNA disappears

How does a cell change as it moves through the different phases of the cell cycle?
a) ATP is converted to Glucose
b) Oxygen is released
c) Two cells become one cell

How are fermentation and respiration different?
a) Oxygen is not used in fermentation.
b) Oxygen is needed in fermentation.
c) Both processes break down sugar to release energy.
d) Both processes convert energy to make sugar.

How are fermentation and respiration similar?
