In Nepal, universities have a chancellor as ceremonial head. The de facto head of the university is the vice-chancellor. The chancellor is primarily responsible for attending the convocation programmes and accepting the resignation and appointment letter of a new vice-chancellor.
Three main types of phytoplankton are: 1  Cyanobacteria (blue-green algae). 2  These are very small and difficult to study. 3  They may be found in large blooms - it is the color of a cyanobacteria that causes the name (and occasionally, color) of the Red Sea.
Within the plankton, holoplankton spend their entire life cycle as plankton (e.g. most algae, copepods, salps, and some jellyfish). By contrast, meroplankton are only planktic for part of their lives (usually the larval stage), and then graduate to either a nektic or benthic (sea floor) existence. Bacterioplankton, bacteria and archaea, which play an important role in remineralising organic material down the water column (note that the prokaryotic phytoplankton are also bacterioplankton). 2  Mycoplankton, fungi and fungus-like organisms, which also are significant in nutrient cycling, as bacterioplankton.
