Photosynthesis Basics

What is the process by which plants make their own food using sunlight?

• Hydrolysis

• Respiration

• Chloroplast

• Photosynthesis

Which pigment in plants absorbs sunlight for photosynthesis?

• Carotenoid

• Xanthophyll

• Melanin

• Chlorophyll

What gas is taken in by plants during photosynthesis?

• Oxygen (O2)

• Nitrogen (N2)

• Hydrogen (H2)

• Carbon dioxide (CO2)

What is the waste product released by plants during photosynthesis?

• water

• carbon dioxide

• oxygen

• nitrogen

Where does photosynthesis mainly take place in a plant cell?

• nucleus

• cytoplasm

• mitochondria

• chloroplasts

What is the primary source of energy for photosynthesis?

• Sunlight

• Wind power

• Nuclear energy

• Coal

What are the two main stages of photosynthesis?

• Light reactions and Calvin cycle

• Photosystem I and Photosystem II

• Dark reactions and Krebs cycle

• Stroma and Thylakoid membrane

How does the process of photosynthesis benefit the environment?

• Photosynthesis benefits the environment by causing soil erosion.

• Photosynthesis benefits the environment by reducing the amount of carbon dioxide in the atmosphere.

• Photosynthesis benefits the environment by depleting the ozone layer.

• Photosynthesis benefits the environment by increasing the amount of carbon dioxide in the atmosphere.
