Cell Essential Vocab Flashcards
The movement of materials against a concentration difference; requires energy
Active Transport
Basic unit of all forms of life
Cell
Process by which particles tend to move from an area where they are more concentrated to an area where they are less concentrated
Diffusion
The process of taking material into the cell by means of infoldings, or pockets, of the cell membrane
Endocytosis
When the concentration of the substance on both sides of the membrane is the same
Equilibrium
Process by which cells release large amounts of material
Exocytosis
Organisms whose cells contain a nucleus
Eukaryote
Process of diffusion in which molecules across the membrane through membrane cells
Facilitated Diffusion
When comparing two solutions, the solution with the greater concentration of solutes
Hypertonic
When comparing two solutions the solution with the lesser concentration of solutes
Hypotonic
When the concentration of two solutions is the same
Isotonic
Specialized structure that performs important cellular functions within a cell
Organelle
Diffusion of water through a selectively permeable membrane
Osmosis
The movement of molecules across the cell membrane without using cellular energy
Passive transport
Unicellular organism that lacks a nucleus
Prokaryote
