Beno Zerr Â· ENSTA Bretagne. Bessel functions are used to solve in 3D the wave equation at a given (harmonic) frequency. The solution is generally a sum of spherical bessels functions that gives the acoustic pressure at a given location of the 3D space.
Some freshwater protists have contractile vacuoles, a specialized form of vacuole that they use to manage water balance within the cell by pumping out excess water. Plant cells have very large vacuoles which function in storing nutrients and water within the cell. They can also serve a structural function by helping the plant cell to retain its shape through turgidity. Vesicles typically function through transportation of compounds within and between cells. Often, the substances within a vesicle will be cellular products or byproducts of a cells functioning. Typically vesicles function in much the same way in all cells. Vacuoles serve a variety of functions depending on the cell in which they are found. In most animal cells where vacuoles occur, they function in the temporary storage of food substances.
