Cell Flashcards
This man Improved the design of the microscope and first observed the cells of the cork.
Robert Hooke
In this published work by Robert Hooke, he viewed a part of a cork under his microscope and observed box-like structures that reminded him of the cells found in a monastery thus naming those as cells.
Micrographia
During the 1800s, two scientists came up with the idea of the cell theory. Name this German botanist who eventually realized that all plants were made up of cells.
Matthias Schleiden
Name this German animal biologist who also realized that all animals were made up of cells. He reached out to other scientists about this discovery and Schieden was the only one responding, and they started to create the postulate of the cell theory
Theodor Schwann
Initially, Schleiden and Schwann disagreed on the third postulate because Schleiden believed that cells undergo free-cell formation wherein they just pop up spontaneously like mushrooms.
c. All cells come from pre-existing cells by division (Third Postulate)
Name the first postulate of cell theory created by both Theodor Schwann and Matthias Schleiden.
a. All known living things are made up of cells
Name the second postulate of cell theory created by both Theodor Schwann and Matthias Schleiden.
b. A cell is the structural and functional unit of all living things
Name the fourth postulate of cell theory created by both Theodor Schwann and Matthias Schleiden.
d. Cells contain hereditary information which is passed on to new cells during cell division
This German physician settled the misunderstanding between Schleiden and Schwann about the 3rd postulate of cell theory and said that cells do come from pre-existing cells
Rudolf Virchow
These organisms are only made up of only one cell that carries out all the functions needed by the organism.
Unicellular Organisms
These organisms are composed of more than one cell, with groups of cells differentiating to take on specialized functions.
Multicellular Organisms
Name this theory which presumes that an ancient Archaean (prokaryotic) cell engulfed a bacterial cell and created this symbiotic relationship that eventually evolved into becoming a eukaryotic cell
endosymbiotic theory
Professor Masaharu Takemura stated that these creatures have something to do with the eukaryote nucleus for one particular reason: they are able to contain the genetic material in a separate compartment.
large DNA viruses
The Medusavirus has been considered one major leap for the researchers at Tokyo University because they found out that it also contained these proteins which are originally just seen in the nucleus of a eukaryotic cell and function in packing and curling the DNA
Histones
The term prokaryotic is a combination of two conjoined words: pro and karyon which means.
Before and Nucleus
These cells are considered as primitive cells because of the lack of nucleus
Prokaryotic Cells
