1. The movement of ANY substance from an area of high concentration to an area of lower
concentration is termed as ___passive transport and diffusion____________.
2. __active_ __transport___________ is the movement of substances across the cell membrane
with the use of energy.
3. Water passes into and out of cells by the process of osmosis_______
4. A plant wilts if water from the vacuoles leaves the cells and evaporates. The process by which
this occurs is _Plasmolysis____
5. A one-celled organism like amoeba can engulf a particle of food and bring it into the cell by
using energy. This type of transport into the cell is called __Endocytosis or phagocytocis_____
6. If red blood cells are put in distilled water they will swell and burst. This is an example of
__Lysing
7. The aromas that are released from cooking and baking food reach the corners of your home
and your nose by __Diffusion_____
8. An apple tree transports sugar from the leaves to the developing apple even through there is
already a higher concentration of sugar in the fruit cells. This is an example of _active___
_____transport____.
9. Three terms for processes that move substances without the use of energy by the cell are
__Osmosis_,Diffusion__, and __Passive __Transport________
10. A selectively permeable membrane is necessary for the process of __osmosis______ and
_____Diffusion____
