|
Vacuole |
"Storage bubbles" that are found in plant & animals cells. |
|
|
Endocytosis |
cell eats large molecules or germs |
|
|
Pumps |
proteins in the cell membrane, molecules go from low to high concentration |
|
|
Hypotonic Solution |
*the solution has less solute than the cell
*water enters the cell
*cell swells |
|
|
Hypertonic Solution |
*the solution has more solute than the cell
*water leaves the cell
*cell shrinks |
|
|
Semi-permeable |
Only lets certain things in and out |
|
|
Osmosis |
Diffusion of water |
|
|
Diffusion |
Faster at hotter temperatures and if there is a bigger concentration difference |
|
|
Hydrophobic |
Water-fearing |
|
|
Hydrophilic |
Water-loving |
|
|
Protein channel |
A tunnel for large & hydrophilic molecules to get through |
|
|
Phospholipid |
*forms a bilayer
*has hydrophilic heads & hydrophobic tails ; main part of membranes |
|
|
Glycoprotein |
Recognized by immune system |
|
|
Cholesterol |
Makes the membrane more sturdy |
|
|
Bulk transport |
*the movement of proteins & polysaccharides into or out of the cell |
|
|
Exocytosis |
Cell ejects materials |
|
|
Active transport |
Cell uses energy |
|
|
Isotonic Solution |
*the solution has the same amount of solute as the cell
*no water moves into or out of the cell
*cell stays the same
*saline solution |
|
|
Facilitated Diffusion |
*large or hydrophilic molecules go from high to low concentration through a protein channel |
|
|
Aquaporin |
Protein channel just for water |
|
|
Passive transport |
*no energy needed
*molecules move from high to low concentration across the membrane |
|
|
Vacuole |
"Storage bubbles" that are found in plant & animal cells. |
