Answer:

• Select the lowest power objective lens. Turn the coarse focus knob slowly until you are able to see the cells. Turn the fine focus knob slowly until the cells are in focus and you can see them clearly. Repeat steps 1-5 using the higher power magnification to see the cells in more detail.

• Robert Hook discovered cells in 1655 with the help of compound microscope. He was observing insects, sand, bird feathers, fossils and plants. Once he was observing a thin slice of cork under the microscope he found a framework similar to honeycomb-like structure. He named those structures as cells but those were actually non living cell walls
