Group of answer choices

chlorophyll

water

oxygen

carbon dioxide

Answer 1

Answer: oxygen

Explanation:

The photosynthesis equation is:

water+carbon dioxide + sunlight—> glucose + oxygen

Oxygen is a product of photosynthesis, not used in the process.

Carbon dioxide and water are both used in the process, and chlorophyll traps light energy from the sun.

Hope this helped!

Answer 2

Answer:

C. oxygen

Explanation:

Oxygen is the product of photosynthesis. Photosynthesis is a process in which glucose and oxygen are produced by the combination of carbondioxide gas and water in the presence of sunlight. Glucose is stored in different parts of plant body and oxygen is released in the atmosphere which is used by living organisms. Carbondioxide is taken by the plants from the atmosphere through stomata and water is absorbed by the plant from the soil through roots.
