Photosynthetic bacteria carry out photosynthesis in the absence of
chloroplasts. Explain Why

Dear student,

Chlorophyll is scattered in the cytoplasm found in the thylakoid membrane of some bacteria like Cyanobacteria. As a result, unlike other plants, chlorophylls are not packed tightly in the chloroplast. As a result, even if they lack chloroplast, they can carry out photosynthesis.

Regards,

Dear Friend,
The Cyanobacteria or the Photosynthetic bacteria are the largest and most diverse group of photosynthetic bacteria previously known as blue green algae . These are true prokayotes having no chloroplast but still perform photosynthesis.
The reason for this is that they have chlorophylls which are dispersed in cytoplasm(not packed in chloroplast like photosynthetic eukaryotes). They carry out oxygenic photosynthesis i.e, they use water as an electron donor and generate oxygen during photosynthesis. Their photosynthetic systems closely resembles to that of eukaryotes
Happy to Help ????
