Study Notes
Specialized Cells
- Specialized cells have a specific function in the body, also called differentiated cells.
- Only multicellular eukaryotic organisms have specialized cells.
- Before cells are specialized, they are called stem cells.
- All the DNA in each of your cells is the same; your DNA is your genome.
How cells become specialized
- Stem cells receive signals, called hormones, to become specialized.
- Using the directions in the signals, DNA turns on or off specific genes.
- Based on the activated genes, the cell grows specific structures.
- As a result of these structures, the cell can do its specific function and can never go back to being a stem cell.
Neuron Cell
- Sends messages around the body.
- Has dendrites that connect to other nerves and an axon insulated for fast message transmission.
Red Blood Cell
- Delivers oxygen throughout the body.
- Very small and flexible.
- Loses its nucleus to increase surface area for carrying oxygen.
Sperm Cell
- Swims to the egg.
- Has a flagellum (tail) for swimming.
- Contains lots of mitochondria to provide energy.
Egg Cell
- Grows and divides to form an embryo.
- Extra large with protective outer layers.
White Blood Cell
- Fights disease.
- Produces antibodies to recognize infections.
- Contains enzymes to break down invaders.
Small Intestine Cell
- Absorbs nutrients.
- Has microvilli, finger-like folds that increase the surface area for absorption.
Pancreatic Cell
- Synthesizes, stores, and releases hormones.
- Beta islet cells have lots of ribosomes to make the insulin protein.
- Insulin is received by a receptor protein on the cell surface which opens transport proteins to let glucose into the cell.
Bronchial Cells
- Moistens and protects airways from pathogens to promote gas exchange.
- Ciliated cells produce and sweep mucous which traps irritants and pathogens.
Muscle Cells
- Responsible for movement and support.
- Contain myofibrils, actin and myosin protein fibers, that contract causing movement.
