Difference Between Nucleus And Nucleoid

The nucleus is known as a structure bounded by a membrane. inside the membrane, eukaryotes stored the genetic material and information while Nucleoid is a particular cell in which prokaryotes stores their genetic materials. the basic difference Between Nucleus And Nucleoid is that the Nucleus is large in size and organized well, it is surrounded by a double layer membrane (nuclear membrane). this membrane separates the nucleus from other organelles. on the other hand, the Nucleoid is small in size that is organized poorly. it also lacks a protective or nuclear membrane.

Difference Between Nucleus And Nucleoid in Tabular Form

Nucleus Nucleoid
A nucleus is a membrane-bound structure in which eukaryotes assemble their genetic materials. Nucleoid is a particular area in which prokaryotes assemble their genetic materials.
A nucleus is well organized and is large. Nucleoid is poorly organized and is small.
A nucleus is engirdled by a double layer membrane known as a nuclear membrane which separates the nucleus from other organelles. Nucleoid lacks a protective membrane.
A nucleus comprises several chromosomes. Nucleoid usually contains only one chromosome.
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 not found in a nucleoid.
It is composed of DNA, RNA, enzymes, dissolved ions, histones, and other subnuclear bodies. It is composed of DNA, RNA, histones, and other proteins.
The nucleolus is present in the nucleus. The nucleolus is absent in the nucleoid.
It is spherically shaped. It is irregularly shaped.
It is known as the largest and the well-organized cell. It is known as a small and well-organized cell.
