difference between nucleus and nucloid?
Answers
The nucleus is a membrane-bound organelle within the cytoplasm where the genome is housed in a eukaryote. The nucleoid region is just the spot in the cytoplasm of a prokaryotic cell where the genome happens to be hanging out -- the genome is not separated from the rest of the cytoplasm by any membrane.

Nucleoid
A nucleus is a membrane-bound structure in which eukaryotes store their genetic materials.
Nucleoid is a particular area in which prokaryotes store their genetic materials.
A nucleus is well organised and is large.
Nucleoid is poorly organised and is small.
A nucleus is surrounded by a double layer membrane called nuclear membrane which separates the nucleus from other cell organelles.
Nucleoid lacks a protective membrane.
A nucleus contains many chromosomes.
Nucleoid contains only a single circular DNA molecule.
A nucleus is a spherically shaped organelle.
Nucleoid is an irregularly shaped organelle.
Nucleoplasm and Nucleolus are present in the nucleus.
Nucleoplasm and Nucleolus are absent in a nucleoid.
