Cell Specialization Flashcards
Give 3 examples of unicellular organisms
- Amoeba
- Paramecium
- Euglena
the result when similar cell types group together to perform a common function
Tissue
a specialized structure composed of 2 or more tissues that together perform a specific function
Organ
the result when multiple organs work together
Organ System
a type of cell with long branches that carry messages throughout the body using electrical signaling
Neurons
________ Cells:
- Form is closely related to function
- Optimal performance only in the environment it was designed to function
Specialized Cells
cells that move oxygen and carbon dioxide throughout the body
Red Blood Cells
the ability of cells to become another type of cell
Cellular Potency
Cell Specialization vs Cellular Potency
Highly Specialized > Low Potency
Unspecialized > High Potency
What are the 4 primary levels of cellular potentcy?
- Totipotent
- Pluripotent
- Multipotent
- Unipotent
a single cell’s ability to produce any number of different cell types within an organism
Totipotent
Why are totipotent cells unique?
They can form all the cell types in an organism + the extraembryonic (placental) cells
What are the only totipotent cells?
Embryonic cells within the 1st couple of cell divisions after fertilization
cells that can give rise to other cells that will function within an embryo
Pluripotent
Embryonic Stem Cells have what level of cellular potency?
Pluripotent
