|
what are the functions of the cell wall |
surronds the cell membrane and protects cells. |
|
|
what are the funtions of the cell membrane? |
selectivley permeable lipid bilayer protection let's particles travel through from one side to another |
|
|
endocytosis |
active transport the process of taking particles into the cell by making pockets |
|
|
3 types of endocytosis? |
pinocytosis, phagocytosis, exocytosis(active transport) |
|
|
pinocytosis? small chunks or big chunks? liquid or solid? |
small chunks and liquid |
|
|
hypotonic |
the outside of the cell has lower salt than the inside of the cell |
|
|
hypertonic |
the outside of the cell has higher salt than the inside of the cell |
|
|
isotonic |
the outside of the cell is the same as the inside level 0 equilibrium |
|
|
osmosis |
the diffusion of water |
|
|
diffusion concentration gradient |
move from high concentration to low concentration |
|
|
facilitated diffusion |
need help to move big molecules like salt across cell membrane |
|
|
water can only move across a membrane if it has these 3 things |
1.membrane must be permeable 2.concentration gradient 3.membrane must be moist |
|
|
active transport concentration gradient |
low to high |
|
|
iso |
the same as |
|
|
hypo |
low |
|
|
hyper |
high |
|
|
phospholipid bilayer |
2 layers of lipids embedded proteins |
|
|
true or false? salmon are fresh water and saltwater fish. |
true |
|
|
passive transport dosent require energy active transport requires energy |
true |
|
|
