The function of photosynthesis is to:

To use the sun’s energy to combine water and carbon dioxide and make food/sugar/glucose

Break apart food/glucose/sugar molecules to release energy

The reason people, animals, plants, fungi, and nearly all living things perform the process of cellular respiration is:

to get energy out of food molecules so they can do the work of being alive

to use the sun's energy to make food molecules

The function of cellular respiration is:

To break apart glucose by reacting it with oxygen, then use the released energy to make ATP

To combine carbon dioxide and oxygen

Photosynthesis and cellular respiration are easy to confuse because:

They have the same four compounds/molecules, but the reactants (inputs) of one are the products (outputs) of the other

They have the same function or job in living things

The “6” in front of CO2 in the equations for photosynthesis and cellular respiration means that:

There are six molecules of CO2 in the reactions

CO2 is six times as powerful as O2

There are 12 atoms of carbon in the reactions

Plants give off oxygen because:

It is a waste product of photosynthesis

It is a waste product of cellular respiration

They love us very much and want us to be able to breathe

Scientists have very sensitive machines/instruments that can measure how much carbon dioxide is in the air. On a sunny day, carbon dioxide concentrations near plant leaves would be:

lower close to the leaves than far away, because photosynthesis is using CO2!

higher near the leaves than far away, because cellular respiration is using CO2!

If a scientist measured CO2 concentrations near a plant leaf at NIGHT, what would be true of the carbon dioxide concentration?

high near the leaf, because there is no photosynthesis at night and also because the plant is giving off carbon dioxide from cellular respiration

it would be low near the leaf, because photosynthesis is using it

How would you describe cellular respiration?

Carbon-based molecules from food and oxygen are used to make ATP

ATP and O 2 are used to make sugars

ATP and CO 2 are used to make ADP and Water

What is the equation for aerobic cellular respiration?

C 6 H 12 O 6 + 6O 2 --> --> --> 6CO 2 + 6H 2 O

C 6 H 12 O 6 + 6CO 2 --> --> --> 6O 2 + 6H 2 O

6 CO 2 + 6H 2 O --> --> --> 6O 2 + C 6 H 12 O 6

Organize these options into the right categories

Happens only in plants, algae, and phtoplankton.

ATP is the energy-containing molecule that captures the energy released
