PASSIVE Type of transport that requires energy ACTIVE Type of transport that moves molecules from low to high concentration (against concentration gradient) ACTIVE Type of transport that does NOT require energy PASSIVE Diffusion, osmosis, and facilitated diffusion are all types of this transport. PASSIVE This is the movement of any molecule from an area of high concentration to an area of low concentration (like perfume in the air). DIFFUSION The movement of water molecules across a selectively permeable membrane OSMOSIS This is diffusion with the assistance of a carrier (channel) protein FACILITATED DIFFUSION This type of solution has a higher solute concentration (therefore lower water concentration) than a cell that it is surrounding. HYPERTONIC This type of solution has equal solute concentration (and equal water) to the cell it is surrounding ISOTONIC This form of active transport moves ions against their concentration gradient and is used to conduct nerve impulses SODIUM/POTASSIUM PUMP This type of bulk transport is responsible for removal of large particles OUT of the cell EXOCYTOSIS This type of bulk transport is responsible for moving large particles IN to the cell ENDOCYTOSIS This is the incorporation of fluids into the cell (cell drinking) PINOCYTOSIS This is the incorporation if large solids into the cell (cell eating) PHAGOCYTOSIS Type of cell with NO nucleus PROKARYOTIC All cells have a membrane, DNA, cytoplasm & these RIBOSOMES All organisms are made of cells All existing cells are produced by other living cells The cell is the most basic unit of life THE CELL THEORY Structures that perform jobs for a cell ORGANELLES Cell part that regulates what enters and leaves the cell CELL MEMBRANE Controls all cell activities and stores DNA NUCLEUS Make proteins RIBOSOMES Convert solar energy to chemical energy in a plant during the process of photosynthesis CHLOROPLASTS Make energy from sugars in all eukaryotic cells MITOCHONDRIA Large, fluid-filled organelle in a plant cell that stores water, nutrients and wastes in a plant cell CENTRAL VACUOLE
