Cyanobacteria carry out oxygenic photosynthesis within specialized membrane-bound chloroplasts containing chlorophyll a.
Answer: Answer
Answer
The statement is False. Cyanobacteria are prokaryotes in Kingdom Monera and lack membrane-bound chloroplasts; their photosynthetic thylakoids lie unencapsulated within the cytoplasm.
The statement is false because cyanobacteria are prokaryotic organisms in Kingdom Monera. A key feature of prokaryotes is the absence of membrane-bound organelles, including chloroplasts, nuclei, and mitochondria. Although cyanobacteria produce oxygen during photosynthesis using chlorophyll a, their thylakoid membranes are suspended directly within the cytoplasm.
