Who was the first life on earth?

Ancestors of bacteria

20

The first microbes were observed in

1673

21

Reported that living things are composed of little boxes or cells

Robert Hooke

All living things are composed of cells and come from preexisting cells

Cell theory

23

Describes live microorganisms and is known as the father or microbiology

Anton Von Leeuwenhoek

24

Said cells arise from preexisting cells

Rudolf Virchow

25

The hypothesis that living organisms arise from nonliving matter or a vital force forms of life

Spontaneous generation

The hypothesis that living organisms arise from preexisting life

Biogenesis

27

What happened in Francesco Redi's experiment?
