What does nucleus mean
dedylja [7]
It depends if you're talking about Physical Science or Physics/Biology -- so, I'll give both definitions (: Physical Science: the positively charged central core of an atom, consisting of protons and neutrons and containing nearly all its mass. Physics/Biology: a dense organelle present in most eukaryotic cells, typically a single rounded structure bounded by a double membrane, containing the genetic material. Hope that helped! (:
