Final answer:
Photosynthesis occurs in both prokaryotes and eukaryotes, but the locations where it occurs differ. In eukaryotes, it takes place in specialized organelles called chloroplasts, specifically on the thylakoid membranes within the chloroplasts. In prokaryotes, it occurs in infoldings of the plasma membrane.
Step-by-step explanation:
Photosynthesis occurs in both prokaryotes and eukaryotes, but the locations where it occurs differ between the two.
In eukaryotes, such as plants and algae, photosynthesis takes place inside specialized organelles called chloroplasts. These chloroplasts have a double membrane and contain stacked structures called thylakoids. The process of photosynthesis primarily occurs on the thylakoid membranes within the chloroplasts.
In prokaryotes, like cyanobacteria, photosynthesis takes place in infoldings of the plasma membrane. These infoldings function similarly to the thylakoids in eukaryotic chloroplasts and provide a location for photosynthesis to occur.
