Living cells were discovered by
(a) Robert Hooke
(b) Purkinje
(c) Leeuwenhoek
(d) Robert Brown
Answer : (c)
Cells were first discovered by Robert Hooke in 1665. He observed the cells in a cork slice with the help of a primitive microscope. Leeuwenhoek (1674), with the improved microscope, discovered the free-living cells in pond water for the first time. So, Robert Hooke discovered dead cell but Leeuwenhoek was responsible for the discovery of living cells.
Therefore, option (c) is correct.
