• A type of consumer that feeds on other organisms.

• An organism that decomposes organic material.

• A plant that requires sunlight to grow.

How do plants obtain carbon dioxide for photosynthesis?

• Plants absorb carbon dioxide from the atmosphere through stomata.

• Plants produce carbon dioxide during respiration.

• Plants absorb carbon dioxide through their roots from the soil.

• Plants obtain carbon dioxide from water during photosynthesis.

What is the difference between light-dependent and light-independent reactions?

• Light-dependent reactions require sunlight; light-independent reactions do not.

• Light-dependent reactions occur in the mitochondria; light-independent reactions occur in the chloroplasts.

• Light-dependent reactions produce glucose; light-independent reactions produce oxygen.

• Light-dependent reactions happen at night; light-independent reactions happen during the day.

• Amyloplasts

What are the two main stages of photosynthesis?

• Light-dependent reactions and light-independent reactions (Calvin cycle)

• Photosystem I and Photosystem II

What is the role of sunlight in photosynthesis?

• Sunlight provides the energy needed for the light-dependent reactions.

• Sunlight is used to absorb carbon dioxide from the atmosphere.

• Sunlight helps in the formation of glucose directly.

• Sunlight is not involved in the process of photosynthesis.
