Term
Energy
Definition
Is used during active transport but not passive transport
Term
Facilitated diffusion
Definition
A form of passive transport that uses transport proteins
Term
Endocytosis
Definition
Process by which a cell takes in materials by forming a vacuole around it
Term
Exocytosis
Definition
Process by which a cell expels wastes from a vacuole
Term
Channel Protein
Definition
Transport protein that provides a tubelike opening in the plasma membrane through which particles can diffuse
Term
Passive Transport
Definition
Particle movement from an area of higher concentration to an area of lower concentration
Term
Active Transport
Definition
Particle movement from an area of lower concentration to an area of higher concentration.
Term
Protein Pump
Definition
Protein that must change shape in order to transport particles
Term
Endocytosis
Definition
The cell membrane forms around another substance for example how an amoeba gets its food
Term
Equilibrium
Definition
When the molecules of one substance are spread evenly throughout another substance to become balanced
Term
Osmosis
Definition
The diffusion of water thru a cell membrane
Term
Diffusion
Definition
When molecules move from areas of high concentration to low concentration
Term
Isotonic
Definition
Equal amount of solute molecules
Term
Hydrophilic
Definition
Water loving
Term
Concentration Gradient
Definition
Term
Hypotonic
Definition
Having less solute molecules than the cytoplasm of the cell
Term
Selectively Permeable
Definition
Allows certain molecules to pass through, keeps some molecules out.
Term
Concentration
Definition
The amount of molecules in a specified area
Term
Solvent
Definition
Fluid that dissolves a solid, liquid, or gas
Term
Solute
Definition
Substance that is dissolved
Term
Turgor Pressure
Definition
Outward pressure on cells
Term
Solution
Definition
Mixture of a substance that is dissolved in another
Term
Hypretonic
Definition
Having more solute molecules than the cytoplasm of the cell
Term
Phospholipid bilayer
Definition
Structure that consists of 2 layers of lipids
Term
Hydrophobic
Definition
Water fearing
Term
Concentration Gradient
Definition
Difference in the amount of molecules between two areas
Term
Carbohydrate Chain
Definition
Structure that identifies the cell
Term
Cholesterol
Definition
Structure that allows cells to communicate with each other to work as a unit
Term
Cell Wall
Definition
Rigid, tough made of cellulose. Protects and supports the cell. Found in plants.
Term
Cell Membrane
Definition
Thin covering, protects cell. Performs active and passive transport. Moves materials in and out of the cell. Found in plants and animals
Term
Cytoplasm
Definition
Jelly-like substance that contains organelles,. Pads and supports organelles inside the cell. Found in both.
Term
Nucleus
Definition
Dense, ball shaped structure, contains DNA. Found in both
Control all cell's activities
Term
Nuclear Membrane
Definition
Thin covering over the nucleus.
Covers and protects the nucleus.
Found in both.
Term
Nucleolus
