Question

Do all organisms which carry out photosynthesis have chloroplasts? explain your answer as fully as you can.

Answer 1

Yes. For photosynthesis to occur a chemical reaction has to take place using chloroplasts and sunlight and water, to result in the production of glucose,water and oxygen. If any of the reactants or products are removed, the reaction does not occur. Thus, yes we require chloroplasts to allow an organism to undergo photosynthesis.

Answer 2

Answer:

No

Explanation:

Not every organisms which photosynthesize have chloroplasts. Cyanobacteria are prokaryotes, so they lack most organelles defined by a membrane. They don’t have chloroplasts, but they photosynthesize.
