Energy (photosynthesis & cell respiration)

Which of the following best explains the purpose of photosynthesis?

• In photosynthesis, sunlight is used to make glucose (sugar)

• In photosynthesis, sunlight is used to make CO2

• In photosynthesis, glucose (sugar) is used to make ATP

• In photosynthesis, oxygen is used to make glucose (sugar)

How do organisms get the energy they need?

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

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

• 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.

Chlorophyll is green because

• it absorbs green wavelengths of light
• it absorbs blue and yellow wavelengths of light
• it reflects green wavelengths of light
• it is an optical illusion caused by the transmission of light

Where do the light-dependent reactions occur? 

• thylakoid membrane
• stroma
• mesophyll
• mitochondria

what are the products of the light reactions

• thylakoid

• oxygen

• ATP

• NADPH
