  4. 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.

  44. 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.

  46. 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'.
