What structures were first observed by Camillo Golgi in 1898?

Step-by-step solution

Camillo Golgi (1898) first observed densely stained reticular structures near the nucleus. These were later named Golgi bodies after him . They consist of many flat, disc-shaped sacs or cisternae of 0.5 µm to 1.0 µm diameter. These are stacked parallel to each other. Varied number of cisternae are present in a Golgi complex.
