30 Cards in this Set

  • Front
  • Back
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.
