What are the main products of the light-dependent reactions of photosynthesis?

• Glucose and Oxygen

• ATP and Glucose

• ATP and NADPH

• Carbon dioxide and Water

Why do plants appear green in color?

• They absorb green light

• They reflect green light

• They emit green light

• They convert green light into chemical energy

Which enzyme is responsible for fixing carbon dioxide in the Calvin cycle?

• Cytochrome

• Rubisco

• ATP synthase

• Photosystem II

What is the primary function of the Calvin cycle in photosynthesis?

• To produce oxygen

• To generate ATP

• To fix carbon dioxide into glucose

• To split water molecules

What triggers photorespiration in plants?

• Low levels of oxygen

• High levels of carbon dioxide

• High levels of ATP

• Low levels of carbon dioxide

Which adaptation helps CAM plants minimize water loss?

• Opening stomata at night

• Closing stomata at night

• Increasing leaf thickness

• Developing deeper roots

What is the main advantage of C4 photosynthesis?

• It allows plants to grow in colder climates

• It allows plants to use less sunlight

• It minimizes water loss while maximizing carbon dioxide intake

• It speeds up the growth rate of plants
