Fluids crossing a membrane
Two ways fluids can pass
Osmosis
Osmosis: H2O moving from an aria of high concentration to an aria of lower concentration.
Diffusion
Diffusion: is movement in liquids and gasses form an aria of higher concentration to an aria of lower concentration.
In a cell this would include
-co2
-o2
-sugars
Fluid movements in plant
Xylem Tissues
Xylem Tissues: Brings water and minerals that were absorbed by the roots to the rest of the cells.
Phloem Tissues
Phloem Tissues: Moves sugars made on the leaves through out the rest of the plant.
Three types of membrane
Selectively permeable
Selectively Permeable: Only some things can get past it
Permeable
Permeable: Anything can get past it
Impermible
Impermeable: nothing can get past it
