    Aristotle And Spontaneuos Generation
    Spontaneous Generation: The coming to life of animals through inatimate objects.
  • micrographia, Robert Hooke

    micrographia, Robert Hooke
    In 1665 Hooke published Micrographia, a book talking about his microscopic and telescopic observations.
  • Fransisco Redi

    Fransisco Redi
    Redi Produced a series of expiraments ultimately proving false of Spontaneous Generation.
    Redi did an expirament with three containers. each hd meat in them. one was sealed, one was open, and one had gauze on the top. the sealed one didnt produce flies, the open one did, the one with guaze also did. which proves that meat cannot produce flies. also it proves that the air can not produce flies. it proved that only flies can produce other flies.
  • Antonie Van Leeuwenhoek

    Antonie Van Leeuwenhoek
    Discovers infusoria
    :Infusoria is a collective term for minute aquatic creatures like ciliates, euglenoids, protozoa, and unicellular algae that exist in freshwater ponds.
  • Antonie van Leeuwenhoek

    Antonie van Leeuwenhoek
    Discovers Bacteria
    : Bacteria are a large group of unicellular microorganisms.
  • Antonie van Leeuwenhoek

    Antonie van Leeuwenhoek
    Discovers Spermatoza
    : is the haploid cell that is the male gamete. It joins an ovum to form a zygote.
  • Lifeforce

    From the time of Spontaneous Generation till It was proven to be false.
    Life force is what was beleived to give life to things such as animals. Redi Did expiraments to prove there was no life force in the air. and that only animals can come from other animals.
  • John Needham-Spontaneous generation

    John Needham-Spontaneous generation
    Did expiraments to show that life was able to be generated from non-living material. But was later proved wrong.
  • Lazarro Spallanzani

    Lazarro Spallanzani
    Spallanzani was a Catholic who researched the theory about the spontaneous generation of cellular life in 1768. His experiment proved that microbes move through the air and that they could be killed through boiling. This work paved the way for later research by Louis Pasteur.-
  • Robert Brown

    Robert Brown
    Robert Brown discovered the cell nucleaus and cytoplasmic streaming. he also helped pioneer the use of the telescope helping the science world advance.
  • Matthias Jakob Schleiden

    Matthias Jakob Schleiden
    Schleiden was a German Boanist who was one of the first to recognize the importance in the cell's nucleus. He stated that the different parts of plants are composed of cells. He was also the co-founder of the cell-division theory. These were crucial discoveries which allowed the sciences to advance greatly.
  • Theodor Schwann- cell theory

    Theodor Schwann- cell theory
    Schwann made many advances, particularily in the area of the cytoplasm in the plant cell. He discovered its jelly like substance, he also saw that the cytoplasm of an animal cell is completely different and that it serves a different purpose. Schwann also inquired into spontaneus generation he disproved this theory.
    He also discovered that new plant cells come from the nucleus of old cells.
  • Louis Pastuer

    Louis Pastuer
    Louis Pastuer discovered a system that allows you to "pastuerize" milk and wine this means making them safe to drink. He also made many other discoveries such as vaccination and the polarity of light.
  • Rudolf Vrichow

    Rudolf Vrichow
    The founder of leukemia cells- Virchow reafirmed that cells can only come from other preexisting cells. he he also challenged against spontaneus generation.
  • modern cell theory

    modern cell theory
    The Cell Theory states that:
    -All living things are made up of one or more cells and the materials produced by these cells
    -All functions take place in the cell, making cells the tiniest unit of life
    -all cells or created be already existing cells through cell division. NOT SPONTANEUS GENERATION
