- circulatory system
- transportation of nutrients TO CELLS and WASTES AWAY
- concentration gradient
- the difference in concentration between a region of GREATER CONCENTRATION and a region of LESSER CONCENTRATION
- cyclosis
- a type of circulation occurring INSIDE a cell, in which there is a streaming motion of cytoplasm
- active transport
- a process in which a membrane requires the expenditure of cellular energy
- diffusion
- the movement of molecules or particles from an area of lesser concentration
- endocytosis
- movement of a substance by a vesicle to the INSIDE of a cell
- facilited diffusion
- transport of substances THROUGH a cell membrane down a concentration gradient aided by carrier proteins
- phloem
- the tissue that conducts food and other dissolved materials throughout the plant
- plasmolysis
- the ,movement of water out of a cell (osmosis) it results in the collapse of the cell
- transport
- all the process by which substances pass INTO OR OUT OF cells and circulate within the organism
- vascular tissue
- the xylem and phloem of a plant (connecting tissue)
- xylem
- the tissue that conducts water and minerals from the roots upward through the plant, helps to support the plant
- passive transport
- transport movement of a substance WITHOUT the use of energy by the cell
- exocytosis
- movement of a substance by a vesicle to the OUTSIDE of a cell
- osmosis
- flow of water of LOW CONCENTRATION TO HIGH
