Which of the following options best explains how less chlorophyll would affect the process of photosynthesis in plants?

Group of answer choices

It would limit the amound of light absorbed by the plant and decrease the amount of food the plant is able to produce for itself.

It would increase the rate of photosynthesis becasue of the increased production of food.

It would limit the amount of water plants are able to take in, resulting in a slower rate of photosynthesis.

It would increase the production of oxygen becasue the plant would need to work hard to feed themselves.

Draw a molecule and yeah that's basically it

After you set up a fish tank, you are sure to see algae growing in it. There is plenty of light, fertilizer in the form of fish droppings, and plants or glass for algae to cling to. You may see green strings of algae in the water or green spots growing on the glass. Your whole aquarium can turn green if you don’t stop the algae. To prevent the problem, you can add algae-eating fish or microorganisms to the water. Covering the aquarium for a few days will also kill algae, which need photosynthesis to survive.

Multi-celled algae grow into larger organisms through cell division. For one-celled algae, the purpose of cell division is
