Photosynthesis Practice

In which organelle does photosynthesis take place?

• Plant cell

• Chloroplast

• Mitochondria

• Endoplasmic Reticulum

Which of the following structures are NOT involved in photosynthesis?

• Thylakoid membranes

• Stroma

• Chloroplast

• Cytoplasm

In addition to sunlight and chlorophyll, photosynthesis requires:

• Water and oxygen

• Water and glucose

• Oxygen and carbon dioxide

• Water and carbon dioxide

The leaves of a plant most often appear green because chlorophyll:

• Reflects the green light

• Absorbs the green light

• Reflects all the light, except green

• Absorbs all the light, including green

The products of photosynthesis are:

• Glucose and oxygen

• Glucose and carbon dioxide

• Water and carbon dioxide

• Hydrogen and oxygen

What is the function of chlorophyll?

• To be green

• To photosynthesize

• To absorb light energy

• To transfer energized electrons

What does the energy from sunlight actually do to the plant cell?

• It heats up the plant cell

• It excites electrons

• It is unknown

• It transforms to kinetic energy

Where do the light-dependent reactions take place?

• In the mitochondria

• In the thylakoid membranes

• In the stroma

• In the cytoplasm

Which are required for the light-dependent reactions to take place:

• CO2 and H2O

• CO2 and sunlight

• O2 and sunlight

• H20 and sunlight

Light dependent reactions

• They involve CO2 and sunlight being converted to glucose

• They involve H2O being converted to sugar

• They result in NADPH and ATP

• They result in NADPH only
