Bacteria don’t have chloroplast. They are unicellular single-celled organisms. Their cells are prokaryotic in nature. The cells don’t have membrane-bound organelles. As they don’t contain membrane bound organelles, thus chloroplast being a membrane-bound organelle absent in the bacterial cell. Chloroplast: The chloroplast ...
