Phosphorescence is a phenomenon associated with which algal division

Phosphorescence is related to fluorescence in that the phosphorescent does not re-emit the radiation it absorbs. It is a process in which the absorbed energy of a substance is released relatively slowly inn the form of light. One example of this is the glow in the dark stick. The stick will glow even brighter if it is exposed in a light material. Another example that is a phosphorescent associated in algal division are the Pyrocystis fusiformis. They are dinoflagellates and can glow brighter at lighter conditions

If you eat to much it could kill you.
