The correct answer is A. Chloroplasts.
Chloroplasts are 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 glucose and oxygen. Chloroplasts are green because they contain chlorophyll, a pigment that absorbs sunlight.
Plastids are a type of organelle found in plant cells. They are responsible for a variety of functions, including photosynthesis, storage, and reproduction. There are many different types of plastids, each with its own unique function.
Lipids are a type of molecule that is found in all cells. They are important for cell structure and function. Lipids are also a source of energy for cells.
Plasmids are small, circular pieces of DNA that are found in bacteria. They can be transferred from one bacterium to another, and they can carry genes that confer resistance to antibiotics or other drugs.
In conclusion, the correct answer to the question “Which cell organelles are involved in photosynthesis?” is A. Chloroplasts.
