Golgi Apparatus
|
Packages materials to be transported out of the cell, located in the cytoplasm, both plants and animals
|
|
Ribosome
|
responsible for the production of proteins, in the cytoplasm, both
|
|
nucleolous
|
produces ribosomes, in the nucleus, both
|
|
lysosomes
|
sac that contains digestive enzymes, cytoplasm, mostly animals
|
|
Smooth ER
|
breaks down toxic substances in liver, cytoplasm, both
|
|
Centriole
|
help in animal cell division
|
|
Dynamic Equilibrium
|
Equal but moving
|
|
Hypotonic
|
The concentration of water outside the cell is higher than the concentration of the water inside the cell.
|
|
Hypertonic
|
The concentration of water inside the cell is higher than the concentration of the water outside the cell.
|
|
Isotonic
|
The concentration of water outside the cell is the same as the concentration of the water inside the cell.
|
|
Cytolysis
|
A cell bursts because it diffuses too much water into it (animal cells only)
|
|
Plasmolysis
|
Cell shrivels due to lack of water (plant cells only)
|
|
Turgor Pressure
|
Large central vacuole swells to take in extra water (plant cells only)
|
|
Equilibrium
|
concentration of molecules is the same inside cell and outside cell, but movement still occurs
|
|
Osmosis
|
process by which water molecules diffuse across a cell membrane to a lower concentration
|
|
Diffusion
|
the movement of molecules from an area of high concentration to an area of low concentration
|
|
Facilitated Diffusion
|
Way of exchanging particles that uses carrier proteins
|
|
Carrier Proteins
|
assist in transporting molecules and change shape
|
|
Ion Channels
|
Small passage along membrane which responds to stimuli
|
|
Sodium-Potassium pump
|
actively transports Na+ and K+ up their concentration gradients
|
|
Endocytosis
|
Cells take external particles into the cell to be released
|
|
Vesticle
|
portion of cell membrane which pinches off to assist in endo/exocytosis, digested by lysosome
|
|
Exocytosis
|
Cells release internal particles out into the enviornment around the cell. Materials are packaged in the Golgi apparatus.
|
|
Pinocytosis
|
"Cell drinking", a type of endocytosis, involves transport of fluids
|
|
Phagocytosis
|
"Cell Eating", involves movement of particles, a type of endocytosis
|
|
Bilayer
|
the arrangement of phospholipids in cell membrane. Heads are hydrophilic, tails are hydrophobic.
|
|
Marker proteins
|
Helps the body identify cells as its own, contains unique carbohydrate chain
|
|
Receptor Proteins
|
Recieve signals from molecules outside the cell, like hormones, which bind to the cell
|
|
Transmembrane Proteins
|
Location classification of proteins, located all across cell membrane
|
|
Peripheral Proteins
|
Location classification of proteins, located on one side of the cell membrane or the other.
