Question

photosynthesis occurs in both prokaryotes and eukaryotes. how do the locations where photosynthesis occurs differ in prokaryotes and eukaryotes?
a. photosynthesis takes place on the folds of the cell membrane in prokaryotes, and in specialized organelles like chloroplasts in eukaryotes.
b. photosynthesis takes place in specialized structures called pill in prokaryotes, and outside of the cell wall in eukaryotes.
c. photosynthesis takes place in specialized organelles like chloroplasts in prokaryotes, and on the folds of the cell membrane in eukaryotes.
d. photosynthesis takes place outside of the cell wall in prokaryotes, and in specialized structures called pill in eukaryotes.

Explanation:

• Option A: In prokaryotes (like cyanobacteria), photosynthesis occurs on the folds of the cell membrane (thylakoid - like structures). In eukaryotes (such as plants), it occurs in specialized organelles - chloroplasts. This option correctly describes the location differences.
• Option B: In prokaryotes, photosynthesis does not occur outside of the cell wall. And in eukaryotes, it occurs in chloroplasts (not just any specialized structures called pill).
• Option C: In prokaryotes, photosynthesis is not in specialized organelles (they lack membrane - bound organelles like chloroplasts in the traditional sense).
• Option D: In prokaryotes, photosynthesis is not outside of the cell wall.

Answer:

A. Photosynthesis takes place on the folds of the cell membrane in prokaryotes, and in specialized organelles like chloroplasts in eukaryotes.
