Cell Structure and Function

Question or Hint Answer or Word

Solution has more particles and less water causing water to flow out of cell and cell to shrink. Hypertonic
Solution has less particles and more water causing water to flow into cell and cell to swell or lead to lysis. Hypotonic
There is a balance in particles and water molecules within solution and cell. Isotonic
A process resulting from osmosis in which cells, in a hypertonic solution, shrink and acquire a scalloped surface. Crenation
A particle or substance that is dissolved within another substance. Lysis
PARTICLES moving from an area of HIGHER concentration TO LESSER concentration. Diffusion
WATER moving from an area of HIGHER concentration of water TO LOWER concentration of water. Osmosis
When proteins cross cell membrane going AGAINST GRADIENT (going from low to high); requires energy to complete this transport - uses ATP . Active Transport
When a membrane allows some molecules to pass through but not others; depends on charge, size and lipid soluability. Selective Permeability
