What is photosynthesis?

• The process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.

• The process by which animals convert carbon dioxide into oxygen.

• The process by which plants convert sugar into carbon dioxide and water.

• The process by which sunlight is absorbed by the soil to nourish plants.

Why are plant leaves green?

• Because they absorb green light.

• Because they are covered in a green substance.

• Because they produce green oxygen.

• Because green is the color of the chlorophyll pigment that reflects sunlight.

What are the two major stages of photosynthesis?

• Water absorption and glucose production.

• Carbon dioxide absorption and oxygen release.

• Oxygen production and sugar consumption.

• Light-dependent reactions and light-independent reactions.

What does chlorophyll absorb?

• Energy from blue- and red-light waves.

• Only sunlight.

• Carbon dioxide from the air.

• Only green-light waves.

Where does the light-dependent reaction take place?

• Outside the plant cell.

• Within the thylakoid membrane.

• In the chloroplast membrane.

• In the stroma.

What is the Calvin cycle also known as?

• Chlorophyll cycle.

• Oxygen-producing cycle.

• Light-absorbing cycle.

• Light-independent reactions.

What is a benefit of C4 photosynthesis?

• It allows plants to produce more oxygen.

• It enables plants to thrive in environments with a lot of light and water.

• It produces a higher amount of chlorophyll.

• It allows plants to thrive in environments without much light or water.

What does ATP stand for?

• Advanced photosynthesis technique.

• Adenosine triphosphate.

• Atmospheric pressure temperature.

• Automatic transfer of plants.

What is the role of NADPH in photosynthesis?

• It converts oxygen into carbon dioxide.

• It is a type of chlorophyll.

• It is used for energy.

• It is used to absorb sunlight.

What is the main product of photosynthesis?

• Water.

• Sunlight.

• Carbon dioxide.

• Oxygen and simple sugars.
