3.5 Quiz

One way to determine if photosynthesis is occurring is to measure the _______________________ output.

• carbon dioxide

• oxygen

• water

• total

Glucose (C6H12O6) is:

• a part of photosynthesis

• a part of cellular respiration

• A part of both photosynthesis and cellular respiration

• Not a part of photosynthesis and cellular respiration

How do organisms get the energy they need?

• Plants break down the glucose they produced in photosynthesis, and animals get energy from eating other organisms.

• Plants do not require energy because they do not move, and animals get energy by performing exercise.

• Plants get energy from glucose produced in the soil, and animals get energy directly from sunlight.

• Plants get energy from fertilizers, and animals get energy by drinking water.

What is the food that plants produce during photosynthesis?

• chlorophyll

• carbon dioxide

• chemical energy

• glucose

What do animals do with the carbon dioxide produced in their cells during cellular respiration?

• store it for later use

• exhale it in the breathing process

• reuse it during photosynthesis

• combine it with water to make sugar

Green plants produce their own food during photosynthesis. Which of these statements about photosynthesis is true?

• Chlorophyll is one product of photosynthesis.

• Water is one product of photosynthesis.

• Oxygen is one product of photosynthesis.

• Carbon dioxide is one product of photosynthesis.

The products of photosynthesis are the starting materials of cellular respiration.

• true

• false

All cells need energy to carry out life activities. The equation below shows one of the processes cells perform to obtain chemical energy.

Glucose + Oxygen → Carbon dioxide + Water + ATP

What process is shown and what is the role of the final product of this process?

• This process is cellular respiration, which creates ATP, which is a molecule that supplies energy to fuel cell activities.

• This process is photosynthesis, which creates the ATP that absorbs radiant energy from the sun.

• This process is photosynthesis, which creates the water that cells need to create oxygen.

• This process is cellular respiration, which creates the carbon dioxide cells need to generate energy to fuel cell activities.

All cells make their own food using energy from the sun.

• true

• false

ATP is:

• A part of an animal cells process

• A product of cellular respiration

• Stored chemical energy

• All of the answers are correct
