Cards

Term
Cell Membrane or Plasma Membrane
Definition
Phospholipid bi-layer, act as gate or control mechanism to move things in and out of cell
Term
Phosphate Heads
Definition
Make up one layer of the cell membrane, are hydrophilic (like water).
Term
Lipid Tails
Definition
Makes up a layer of the cell membrance, are hydrophobic (do not like water). Keep intracellular fluid in and extracellular fluid out.
Term
Proteins
Definition
Identify what type of cell you are looking at.
Term
Chanel Proteins
Definition
Ability to move things in and out of the cell. Mostly these are gated and only open under certain circumstances.
Term
Nucleus
Definition
Located inside the cell, has a nuclear membrane similar to the cell membrane, also phspholipid bi-layer, but very porous
Term
Deoxyribonucleic Acid (DNA)
Definition
Blue print for our body, found in nucleus, 99% of DNA is identical
Term
Chromatin (unorganized) or Chromosomes (more organized)
Definition
DNA + Histone (protein)
Term
Nucleolus
Definition
An area where nucleic acids "hang out" together
Term
Rhibonucleic Acid (RNA)
Definition
Important to protein synthesis
Term
Mitochondria
Definition
Energy molecule, when nutrients enter a cell this turns it into energy, also known as adenosinetriphosphate (ATP)
Term
Endoplasmic Reticulum
Definition
Conveyer belt, energy is deposited here and transported to the Golgi Apparatus
Term
Golgi Apparatus
Definition
Packaging system, packages the energy to be moved out of the cell by vessicles/vaculous
Term
Vessicles/Vacuoles
Definition
Packaged proten that comes from the Golgi Apparatus to be "spit out of the cell." Carrying the enzyme.
Term
Lysosome
Definition
Janitor, cleans up any bi-product from chemical reaction in cell (there is always bi-product).
