Photosynthesis Quiz

Which organelle is associated with photosynthesis?

• Mitochondrion

• Ribosome

• Chloroplast

• Nucleus

What is the relationship between cellular respiration and photosynthesis?

• They are the same process.

• Cellular respiration is the reverse of photosynthesis.

• Photosynthesis occurs in animals while cellular respiration occurs in plants.

• Cellular respiration uses light energy, while photosynthesis does not.

What is the primary pigment involved in photosynthesis?

• Hemoglobin

• Melanin

• Carotene

• Chlorophyll

What is the significance of light in photosynthesis?

• It is a by-product of the reaction.

• It is used to break down carbon dioxide.

• It is harvested for energy to drive the reactions.

• It is necessary for the absorption of nutrients.

What is photosynthesis?

• A process where animals convert light energy into chemical energy

• A process where plants, algae, and certain bacteria transform light energy into chemical energy

• A method by which plants consume carbon dioxide and produce oxygen without light

• A biological process in humans to generate energy from food

What are the starting materials for photosynthesis?

• Oxygen and glucose

• Nitrogen and helium

• Carbon dioxide and water

• Hydrogen and oxygen

Where is the chemical energy produced in photosynthesis stored?

• In the roots of the plants

• In the oxygen molecules released

• In the bonds of sugar molecules

• In the water molecules used

What are organisms that perform photosynthesis called?

• Heterotrophs

• Carnivores

• Autotrophs

• Decomposers

What role do photosynthetic organisms usually play in their ecosystem?

• Consumers

• Decomposers

• Producers

• Scavengers

How is water transported to the photosynthetic cells in the leaves?

• Through the stem

• Via the roots directly into the leaves

• Veins in leaves carry water to photosynthetic cells

• Through the surrounding air
