Cell Discovery and Theory Flashcards
Cell 1
smallest and basic structural unit of an organism or life, capable of independent functioning
Cell 2
vary in size from 0.5um to 100um with different shapes
Cell Fact 1
100 trillion cells per individual
Cell Fact 2
50 cells in letter āiā dot
Robert Hooke (1665)
- cellulae/cellula (Latin) - house or rooms where monks lived in
- CORK CAMBIUM - non-living tissue found in bark of trees
Aton Van Leeuwenhoek (1673)
- animalcules (rotifers now)
- won an award from looking at tartar and pond droplets
Matthias Schleiden (1838)
- plants are made up of cells
Theodore Schwann (1839)
- animals are made up of cells
Rudolph Virchow (1855)
- cell division, debunked spontaneous generation (life came from non-living matter)
Cellula omni y Cellula
cells come from pre-existing cells
Cell Theory 1
states that all organism are made up of similar units of organizations called cells in 1839
Cell Theory 2
by Matthias Schleiden and Theodore Schwann (in CCT, all 3 & in MCT, just #1), foundation of modern biology
Classical Cell Theory 1
all known living things are made up of cell
Classical Cell Theory 2
cells are the basic unit of structure and function in an organism
Classical Cell Theory 3
cells come from the reproduction of existing cells (cell division)
Modern Cell Theory 1
cell contains hereditary information (DNA + RNA) and passed on to new cells during cell division
Modern Cell Theory 2
all cells are basically same in chemical activity
Modern Cell Theory 3
all basic chemical and physiological functions are carried out inside the cell
Modern Cell Theory 4
cell activity depends on the activities of subcellular structure (cells are inter reliant or all must function)
Lyn Margulis (1970)
parts of cell are free-living before (no membrane but if there is one, it will be an ORGANELLE)
