Photosynthesis Review

Photosynthesis uses sunlight to convert water and carbon dioxide into _________ and ____________.

• glucose and protein

• oxygen and glucose

• ATP and oxygen

• oxygen and carbon

What is the chemical reaction for photosynthesis?

• C₆H₁₂O₆ + 6 CO₂ ----> 6 H₂O + 6 O₂

• 6 H₂O + 6 CO₂ ----> C₆H₁₂O₆ + 6 O₂

What is the purpose of photosynthesis?

• For heterotrophs to make sugars.

• For heterotrophs to make oxygen.

• For autotrophs to make sugars.

• For autotrophs to make oxygen.

Plants capture the sun’s energy using a pigment called __________.

• thylakoids

• chloroplasts

• chlorophyll

• mitochondria

Most plants appear green because chlorophyll ________.

• absorbs green light

• does not absorb green light

• the chemical substance ATP

• does not absorb violet light

Which part of photosynthesis occurs in the Thylakoids of the chloroplast?

• Light reactions / Light dependent reactions

• Dark reactions/ Light independent/ Calvin cycle

What are the products of the light-dependent reactions?

• oxygen and glucose

• ATP, NADPH, and oxygen

• ATP, carbon dioxide, and NADPH

Which part of photosynthesis occurs in the STROMA of the chloroplast?

• Light reactions / Light dependent reactions

• Dark reactions/ Light independent/ Calvin cycle

Which of the following activities happens in the Calvin Cycle?

• ATP is used to convert carbon dioxide to glucose.

• Water is split to produce oxygen and hydrogen ions.

Which of the following does NOT affect the rate of photosynthesis?

• Intensity of sunlight

• Amount of oxygen

• Amount of carbon dioxide

• Amount of water.
