3 parts of the cell theory |
All living things are made up of cells.
Cells are the basic units of structure and function in living things. New cells are produced from existing cells. |
|
|
Robert Hooke |
First person to give the cell its name by comparing it to an actual jail cell |
|
|
Matthias Schleiden
|
Said that all plants are made of cells.
|
|
|
Theodor Schwann
|
Said that all animals are made of cells |
|
|
Rudolf Virchow
|
Said that new cells could be produced only from the division of existing cells

|
transmission and scanning
|
|
|
Produces 2-D images |
Transmission electron microscopes
|
|
|
Produces 3-D images |
Scanning electron microscopes
|
|
|
light microscope
|
Uses focused light to pass through a specimen and uses two lenses to form an image.
|
|
|
Do not separate their genetic material within a nucleus.
|
Prokaryotic cells
|
|
|
Nucleus separates the genetic material from the rest of the cell.
|
Eukaryotic cells

|
|
Nucleus |
Large membrane-enclosed structure that contains the cell’s genetic material in the form of DNA
|
|
|
Cytoplasm |
fluid portion of the cell outside the nucleus.
|
|
|
Vacuoles
|
Store materials such as water, salts, proteins, and carbohydrates
|
|
|
Vesicles
|
Move materials between cell organelles, as well as to and from the cell surface.
|
|
|
Lysosomes
|
Small organelles filled with enzymes that function as the cell’s cleanup crew and break down carbohydrates, lipids and fats
|
|
|
Cytoskeleton
|
network of protein filaments known as micro-filaments and micro-tubules.
|
|
|
Micro-filaments
|
Threadlike structures made up of a protein called actin.
|
|
|
Micro-tubules
|
Hollow structures made up of proteins known as tubulin
|
|
|
Ribosomes
|
Small particles of RNA and protein
|
|
|
Endoplasmic reticulum
|
Forms lipids and transports proteins.
|
|
|
Rough ER |
produces proteins and has ribosomes on itslef
|
|
|
Smooth ER |
produces lipids and doesn't have ribosomes |
|
|
Golgi apparatus
|
Proteins are bundled into tiny vesicles
|
|
|
organ |
made up of muscles |
|
|
organ system |
made up of several organs |

|
muscle |
made up of specialized cells |
|
|
receptor |
receives a signal from another cell |
