Final answer:
It is true that individual ribosomes can be seen with a fluorescence microscope, by attaching fluorescent dye to them, making them visible.
Step-by-step explanation:
The statement 'An individual ribosome can be seen with a fluorescence microscope' is true. Ribosomes, in general, are too small to be seen with traditional light microscopy, but with the aid of fluorescence microscopy, individual ribosomes can become visible. This technique involves attaching a fluorescent dye to the ribosome, which then emits light upon excitation and can be seen through the microscope.
Ribosomes are complex molecular machines found within all living cells where they are responsible for protein synthesis. They consist of two subunits, a small and a large one, each composed of proteins and ribosomal RNA (rRNA).
