Robert hook discovered cells, and Rudolph Virchow developed the cell theory

Casey K said...

Robert Hooke of England looks through a microscope at a sliver of cork. He notices what he calls cells or pores. He believes the cells contained the noble juices or fibrous threads of the tree when it was alive. He is the first person to use the word cellto describe microscopic structures.

Robert Hooke contributed to the cell theory because he discovered cells.

Robert Hook, discovered cells.

John Needham was a scientist that figured out that soup that is exposed to the air had micro-organisms.

VAn Italian physician, Francesco Redi, performed an experiment to see if rotting meat changed into flies. He discovered that only flies to could make more flies, thus disproving the theory of spontaneous generation.

Anton Van Leeuwenhoek, of Holland, used microscopes to view many things including pond organisms, bacteria and blood cells. He made careful sketches of what he observed.

Hugo de Vries, a Dutch botanist, creates the term mutation to describe changes that appear in his experiments with primroses.

Cassie M said...

Lazzaro Spallanzani, a biologist and abbot in Italy tried several variations on the experiments done by John Needham. He discovered that soup that was kept sealed did not contain the micro organisms that appeared in soup open to the air. He determined that micro organisms get into the soup from the air.

Sophia S3 said...

Oswald Avery of the United States announces that DNA is the only substance responsible for heredity.

Among Robert Hooke's greatest contribution to biology is microscopy or his development of compound microscope. They use the compound microscope to demonstrate various types of organisms. He also coined the term 'cell'.

Francis Crick of Britain and James Watson of the US make a model of the DNA molecule. They prove that genes are responsible for heredity.
