Plant Cell and Photosynthesis Quiz

Label the parts of the plant cell in the diagram.

• Nucleus

• Chloroplast

• Mitochondria

• Cell Wall

Write the chemical equation for photosynthesis.

• 6CO2 + 6H2O +light -> C6H12O6 + 6O2

• C6H12O6 + 6O2 -> 6CO2 + 6H2O +light

• 6O2 + C6H12O6 -> 6CO2 + 6H2O

• 6H2O + 6CO2 -> C6H12O6 + 6O2

Which part of the plant is responsible for photosynthesis?

• Root

• Stem

• Leaf

• Flower

Photosynthesis word meaning:

• The process by which plants make their food using sunlight

• The process of breaking down food to release energy

• The movement of water through a plant

• The exchange of gases in the leaves

The hydrogen produced is added to NADP+, which already exists in the cells of the leaf, to make _________. The _________ is not needed and is released by the leaf.

• NADPH

• oxygen

• water

• glucose

• carbon dioxide

Products of the light reactions: i. _________ ii. _________ iii. _________

• glucose

• oxygen

• ATP

• NADPH

• carbon dioxide

The _________ and _________ are energy-rich compounds and are needed for the dark reactions in photosynthesis.

• NADPH and ATP

• Glucose and Oxygen

• Water and Carbon Dioxide

• Chlorophyll and Sunlight

The dark reactions (The Calvin cycle): Why is it called the dark reaction pathway?

• Because it occurs in the absence of light

• Because it occurs in the presence of light

• Because it is a part of the light-dependent reactions

• Because it requires darkness to proceed

Oxygen is sometimes called a “waste product” of photosynthesis because:

• It is not used by the plant for energy.

• It is a byproduct of the photosynthesis process.

• It is harmful to the plant.

• It is released into the atmosphere.

Which of the following statements correctly summarizes how the light reaction and the dark reaction are the same and different?

• Both reactions occur in the chloroplast, but the light reaction requires light while the dark reaction does not.

• The light reaction produces glucose, while the dark reaction produces oxygen.

• Both reactions occur in the mitochondria and require light.

• The dark reaction occurs only during the night, while the light reaction occurs only during the day.
