Question

Since,there is no chloroplast in the prokaryotic cells,so how they photosynthesis by their cell membrane?

Answer 1

$\huge\sf\underline{Answer}:$

However, prokaryotes, such as cyanobacteria, lack membrane-bound organelles (including chloroplasts). Prokaryotic photosynthetic organisms have infoldings of the plasma membrane for chlorophyll attachment and photosynthesis (Figure 1). It is here that organisms like cyanobacteria can carry out photosynthesis.
