Question

Robert Hooke actually observed .......... of cells.

• A. Cell walls.
• B. Protoplasts.
• C. Wall-less cells.
• D. Walled cells.

Answer 1

The correct option is A Cell walls.

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. So option A is correct.
