Jorge 10th CHAPTER 8 .1 CELL MEMBRANE
Question | Answer |
---|---|
SIMPLE DIFFUSION | The movement of molecules in a high concentration to a low concentration. |
FACILITATED DIFFUSION | the movement of particles across the plasma membrane using transport proteins without the use of energy. |
OSMOSIS | diffusion of water across a selectively permeable membrane.important for maintaining homeostasis.water will move from where there’s more of it to where there’s less of it |
EXOCYTOSIS | transports molecules out of the cell by an intercellular vesicle that fuses to the cell membrane and spills the cell in a process requiring energy. |
ENDOCYTOSIS PHAGOCYTOSIS | is the process by which a cell often a phagocyte or a protest engulfs a solid particle to form an internal compartment |
ENDOCYTOSIS PINOCYTOSIS | type of active transport where the vacuole binds with the plasma membrane and secretes material such as hormones from the cell |
SEMIPERMEABLE | Allowing certain substances to pass through but not others. |
HYPOTONIC | There is more water outside the cell than inside water moves into the cell cell swells up |
HYDROPHOBIC | tending to repel or fail to mix with water. The opposite of hydrophilic. |
HYPERTONIC | hypertonic solutionthere is more water inside the cell than outside |
ISOTONIC | iWhat controls osmosis?isotonic solution. concentration of water is the same inside and outside the cell.no net movement of water into or out of the cell |
HYDROPHILIC | Ability to mix with water |
ACTIVE TRANSPORT | The movement of particles across the plasma membrane against a concentration gradient using energy |
PASSIVE TRANSPORT | The movement of materials through a cell membrane without using energy.. |
