The nucleoid is the space within a prokaryotic cell where the genetic information, called the genophore, is found. Prokaryotes are divided into bacteria and archaea, which are both unicellular organisms that contain no membrane-bound organelles. The nucleoid, then, also has no membrane around it.

Is the nucleoid in plant or animal cells?

The right option is option c) bacteria cell.

The nucleoid is nothing but the space within a prokaryotic cell where all the genetic information called the genophore is found. It is also found in other prokaryotic cells.

Do all cells have a nucleoid?

All prokaryotes have chromosomal DNA localized in a nucleoid, ribosomes, a cell membrane, and a cell wall. The other structures shown are present in some, but not all, bacteria.
