The correct answer is A. Chloroplasts.
Chloroplasts are membrane-bound organelles found in plant cells and algae. They are responsible for photosynthesis, the process by which plants use sunlight to convert carbon dioxide and water into oxygen and glucose. Chloroplasts are green because they contain chlorophyll, a pigment that absorbs sunlight.
Plasmids are small, circular DNA molecules that are found in bacteria and some other prokaryotes. They are not essential for the survival of the cell, but they can confer certain advantages, such as resistance to antibiotics.
Lipids are a type of molecule that is made up of carbon, hydrogen, and oxygen. They are found in all living cells and are used to store energy, build cell membranes, and produce hormones.
The answer to the question is A. Chloroplasts.
