| Term | Definition |
|---|
| homeostasis | maintains balance within the cell (like a athletic adjusting to a new altitude) |
| selectively permeable | the cell membrance chooses what can or cannot leave (like a fish net) |
| phopholipid bilayer | 2 stacks of fats that contain phosphorus that has pores that allow some things to enter and keep others out (the two layers are tail to tail) |
| hydrophilic | polar head |
| hydrophobic | nonpolar tail |
| polar | uneven distribution of electrons |
| transport protein | provides movement of materials across the cell membrane |
| cell | made up of a nucleus,cytoplasm, organelles and held within the cell membrane |
| nucleus | control center of the cell |
| cytoplasm | the fluid that is outside the nucleus, where the organelles are located |
| barrier | the_____ is where the polar heads are closest to the water molecules and the nonpolar tails are be farthest away from the water molecules this creases a ____ is created |
| water-soluable substances | _________ will not move easily through the plasma membrance because they are stopped by the nonpolar middle of the phopholipid bilayer |
| transport protein | provides movement of materials (like waste) across the cell membrane |
| helps | transport protein ________ with selective permeability of the cell membrance |
| phospholipid molecules | the plasma membrane is made up of two layers of _______ ______ |
| proteins | cholesterol and transport _______ aid in the function of the plasma membrane. |
