Description
''Characiochloris'' is a unicellular organism in which the cells are attached to a substrate by an adhesive pad. They are egg-shaped to spindle-shaped with the apical end attached to the substrate. Cells are always uninucleate (with one nucleus
Nucleus (: nuclei) is a Latin word for the seed inside a fruit. It most often refers to:
*Atomic nucleus, the very dense central region of an atom
*Cell nucleus, a central organelle of a eukaryotic cell, containing most of the cell's DNA
