Leeuwenhoek was the first to discover living cells in the year 1674. Anton von Leeuwenhoek first discovered free-living algal cells in water in 1674. Anton von Leeuwenhoek created the compound microscope to see free-living cells. He observed red blood cells, bacteria, and sperm. The cell walls observed by Hook did not show the nucleus or other organelles found in most living cells. Van Leeuwenhoek probably also saw bacteria.

Robert Hooke

  • Robert Hooke was the first scientist to discover cells in 1665.
  • With his homemade microscope, he observed tiny "honeycomb"-like compartments within a thin disc of cork.

Schwann

  • The classical cell theory was proposed in 1839 by Theodor Schwann.
  • This theory consists of three parts.
  • The first part states that all living things are made of cells.
  • Part 2 states that the cell is the basic unit of life.
  • These parts are based on the conclusions reached in 1838 by Schwann and Matthias Schleiden comparing their observations in plant and animal cells. His third part, claiming that the
  • cells were derived from proliferated pre-existing cells, was described by Rudolf Virchow in 1858 as his Omnis cellula e cellula.

Summary:

Living cells were first discovered by which scientists - (a) Leeuwenhoek (b) Robert Hooke (c) Schwann (d) None of the above

Living cells were first discovered by the scientist Leeuwenhoek. He created the compound microscope to observe the free-living cells. He also observed bacteria using the microscope.
