Study for science

Prokaryotic a unicellular organism that lacks a membrane-bound nucleus mitochondria, or any other membrane-bound organelle.
Eukaryotic any organism whose cells contain a nucleus and other organelles enclosed within membranes.
Organelles any of a number of organized or specialized structures within a living cell.
Cell Theory the properties of cells.
Selectively Permeable allows certain molecules or ions to pass through it by means of active or passive transport.
Phospholipid Bilayer A thin polar membrane made by two membranes of lipids
Passive Transport Movement of biomolocules and other atomic substances
Concentration Gradient the process of particles (solutes) move through a gas or a solution from an area with a higher number of particles to an area with a lower number of particles.
Diffusion a region in which they are in higher concentration to regions of lower concentration.
Equilibrium The state in which the concentrations of the diffusing substance in the two compartments are the same or become equal.
Osmosis molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one
Hypotonic having a lower osmotic pressure than a particular fluid, typically a body fluid or intracellular fluid
Isotonic denoting or relating to a solution having the same osmotic pressure as some other solution
Hypertonic having a higher osmotic pressure than a particular fluid, typically a body fluid or intracellular fluid
Facilitated Diffusion the process of spontaneous passive transport of molecules or ions across a cell's membrane via specific transmembrane integral proteins
Active Transport the movement of ions or molecules across a cell membrane into a region of higher concentration
Membrane Pore any of numerous structures with complex openings in a nuclear membrane which allow passage of molecules between the nucleus and surrounding cytoplasm
