What are the fly and membranes and chloroplast called?

The "fly" typically refers to the fruit fly, Drosophila melanogaster, a model organism in genetics and developmental Biology. "Membranes" generally refer to biological membranes, which are lipid bilayers that enclose cells and organelles, regulating the movement of substances. Chloroplasts are organelles found in plant cells and some algae, responsible for photosynthesis, converting light energy into chemical energy stored in glucose. Together, these components play crucial roles in cellular function and energy conversion in living organisms.
