Plants, algae, and many single-celled organisms can photosynthesize using a specialized cell organelle called a chloroplast. Do you think all organisms that photosynthesize have chloroplasts? Use evidence from the video to explain your answer.
The chloroplast is an organelle through which photosynthesis takes place. While the light reaction takes place in the thylakoid membrane of the chloroplast, the light-independent reaction or the Calvin cycle takes place in the stroma of the chloroplast.
No, not all organisms that photosynthesize have chloroplasts. Cyanobacteria are prokaryotes, so they lack most organelles defined by a membrane. They don’t have chloroplasts, but they photosynthesize.
