Movement of water from high to low concentrations.
Three types of transport
Movement of Macromolecules
Type of solution that is more dilute than the other solution.
Type of solution that has more solute and less solvent
Act as name tags for the cell
Loss of osmotic pressure in a plant cell
Part of the phospholipid that faces the cytoplasm or the environment
Hydrophillic phospholipid head
carbohydrates that attach to hydrophillic heads in the membrane
Three types of passive transport
Two components of a solution
Solute (dissolved particles)
Loss of osmotic pressure in an animal cell
Exploding of an animal cell
Type of solution that is more concentrated than the other solution.
Alternate names for cell membrane
Selectively permeable membrane
Fluid Mosaic Model
Type of transport that takes in large molecules into the cell...so large they can't fit through the phospholipids or the integral proteins.
Part of the phospholipid that doesn't like the solvent in the cytoplasm or the environment
Fatty Acid Tails
Type of transport that requires the use of ATP by the cell
attach to glycoproteins
Diffusion through an integral protein from high to low concentration.
Two types of endocytosis
During passive transport how do molecules move?
From high to low concentration
Down the conentration gradient.
Solid food and bacteria enter cells through
Gates within the cell membrane
Type of solution that has more solvent and less solute
Three main molecules that make up a cell membrane
During osmosis water moves from a _______solution to a ___________ solution.
hypotonic to hypertonic
(TO THE HYPER!)
Category of transport that does not require energy from the cell
_______ releases large products or waste molecules out of the cell.
Type of passive transport involves the movement of gases across the membrane from high to low concentrations
Increase in osmotic pressure in an plant cell leads to the cell becoming ____
Type of solution that has the same concentration of solute as the other solution
Hormones and secretions enter a cell through...
