cytology |
the study of cells |
|
|
|
Robert Hooke |
looked at dead cork cells & coined the term “cell” |
|
|
|
Anton van Leeuwenhoek |
observed pond water & coined the term “animalcules” & discovered protists |
|
|
|
Matthias Schieiden |
discovered that cells compose all parts of plants |
|
|
|
Theodore Schwann |
discovered that cells composed all part of animals |
|
|
|
Rudolph Virchow |
discovered that cells come from other or pre-existing cells |
|
|
|
3 parts of The Cell Theory |
1. All living things are composed of one or more cells. 2. Cells are the basic unit of living things. 3. Cells are produced from only pre-existing cells. |

|
Cell Characteristics |
1.All cells have a cell/plasma membrane 2. All cells have cytoplasm 3. All cells have the ability to reproduce themselves 4. All cells possess genetic material |
|
|
|
prokaryotic cells |
no internal membrane- bound compartments, no nucleus, uni-cellular, usually bacteria |
|
|
|
eukaryotic cells |
have internal membrane- bound compartments, have nucleus, uni- and multi- cellular, mostly anything except bacteria |
|
|
|
Cell Membrane- |
complex barrier separating the cell from its external environment |
is a selective permeable membrane |
|
|
selective (semi) permeability- |
allows some molecules to enter while keeps others out |
|
|
|
Cell Wall- |
a fairly rigid structure outside the plasma membrane that provides additional support and protection. animal cells don’t have them. |
|
|
|
Cytoplasm- |
jelly-like material between the cell membrane and the nuclear membrane/envelope |
organelles are embedded in here. chemical reactions occur here. |
|
|
Cytosol- |
the water portion of the cytoplasm |
|
|
|
nucleus |
control center |
|
|
|
nucleus |
control center |
|
|
|
nucleolus |
makes ribosomes |
|
|
|
endoplasmic recticulum |
site of cellular chemical reactions |
|
|
|
endoplasmic recticulum |
can be rough or smooth. involved with transport to the golgi |
|
|
|
endoplasmic rectilium |
arranged in a series of highly folded membranes in the cytoplasm |
|
