Cytoplasm |
the interior part of the cell |
inside parts of the cell |
|
|
Phospholipids |
contains a phosphate and a lipid bonded together. |
circular head (phosphate) and double tails (lipid) what is this called? |
|
|
Phospholipid Bilayer |
when the polar heads are facing outward and the non polar tails are facing outward. |
doublem and contains a phosphate and a lipid that are non polar and polar. |
|
|
Polar |
when the covalent bond has a slight charge. Has a slightly negative end and a slightly positive charge on the other end |
slightly positive, and slightly negative. happens between hydrogen bonds |
|
|
Nonpolar |
has no charge, equally shares the electrons |
no charge, equally shared electrons |
|
|
Transport Proteins |
spread across the bilayer and helps get polar molecules and ions through the cell. |
helps get polar and ions through the cell |
|
|
Selective Permeability |
a cell that allows certain molecules through, by active or passive transport, but doesn't let others. |
allows certain stuff through but not other |
|
|
Glycoproteins |

Fluid Mosaic Model |
flexible structure of the cell membrane |
a model for the cell membrane, and a bendy structure |
|
|
Diffusion |
the movement of a substance, from an area of high concentration to an area of low concentration, in its concentration gradient. |
moves from an area of high to low in the concentration gradient |
|
|
Concentration Gradient |
when there is a difference in the concentration across an area. |
difference in the concentration, high/low |
|
|
Osmosis |
movement of molecules into a higher concentration, towards the direction that equals out the concentration.
|
equalizing the concentration is called________ |
|
|
Turgor |
a swelling of the cell wall caused by the pressure of the cells contents |
swelling of the cell wall cause by the inside parts |
|
|
Isontonic |
the molecule concentration is the same/balanced |
equal amount, moving in and out of the cell in equal amounts |
|
|
Hypotonic |
a lower concentration, usually has more water than solute. |
lower concentration= _________ |
|
|
Hypertonic |
having a higher concentration |
higher concentration means it is ________ |

Passive Transport |
a movement of molecules through the cell membrane that does not require energy. |
does not need any energy to move through the cell membrane is called _______ |
|
|
Active Transport |
the movement of molecules that require energy and move in the direction of a concentration gradient. |
moves in the direction of a concentration gradient is called _______ |
|
|
Facilitated Diffusion |
the process of passive transport through a cell membrane |
process of passive transport through a cell membrane is called _______ |
|
|
Endocytosis |
a form of active transport that uses energy for them to pass through the cell. |
energy using process and is a form of active transport |
|
|
Exocytosis |
a process in which a membrane bounded sphere moves to the plasma membrane and fusion happens between the two. |
a way molecules exit the cell. |
