1665, Robert Hooke reported that?

Living things are made of cells

1858, Rudolf Virchow said...

Cells come from preexisting cells.

What are the two statements of the Cell Theory?

Living things are made of cells and come form preexisting cells.

What did Anton van Leeuwenhoek do in comparison to Hooke?

First to observed microorganisms not blurred.

What is biogenesis?

Living organisms arise from preexisting life.

What is spontaneous generation?

Living organisms arise from nonliving matter

What experiment did Pasteur do? What did he disprove?

Covered/uncovered meat, he disproved spontaneous generation.

Pasteur states that microbes are responsible for...

Fermentation

What does microbial growth do to food?

It spoils it

What is pasteurization?

Application of high heat for a short period of time.

What did Ignaz Semmelweis advocate?

Hand washing to prevent disease spread.

What did Joseph Lister do?

He took Semmelweis' advice during surgery.

What is a vaccination?

Immunity from viruses
