Photosynthesis

Photosynthesis occurs inside of which organelle?

• chloroplasts

• the cell wall

• mitochondria

• ribosomes

Which of the following is converted into chemical energy during photosynthesis?

• oxygen

• sound energy

• light energy

• glucose

How do plants get the carbon dioxide they need for photosynthesis?

• Carbon dioxide is produced in a chemical reaction inside their chloroplasts.

• Carbon dioxide enters their leaves from the atmosphere.

• Carbon dioxide enters their roots from the soil.

• Carbon dioxide is produced in a chemical reaction inside their mitochondria.

In addition to carbon dioxide, ______ is a reactant of photosynthesis.

• oxygen

• glucose

• carbon monoxide

• water

What do plants do with most of the oxygen produced in photosynthesis?

• They use most of the oxygen to make more glucose.

• They release most of the oxygen into the atmosphere.

• They release most of the oxygen into the soil.

• They use most of the oxygen to produce carbon dioxide.

Photosynthesis is important to animals because

• oxygen, which animals breathe, is released as a byproduct.

• carbon dioxide, which animals need for cellular respiration, is released as byproduct.

• it prevents any of the sun's energy from being absorbed by animals' skin.

• it prevents carbon dioxide from destroying animals' habitats.

Animals, including humans,

• do not need glucose.

• make their own glucose.

• get glucose from the food they eat.

• get glucose from the sun's energy.

True or false: Photosynthesis is an important part of the carbon cycle.

• True

• False

What gas  do plants give off after conducting photosynthesis that humans/animals need in order to live?

• Oxygen
• Carbon
• Nitrogen
• Hydrogen
