They are typically smaller than eukaryotic cells.
The DNA of a prokaryotic cell is contained in the nucleoid.
Explanation:
There are several ways in which prokaryotic cells are different from eukaryotic cells. Firstly, they are generally smaller in size, their organelles are not membrane bound, and they have no nucleus. They, however, share commonalities with eukaryotic cells including the presence of a bilipid plasma membrane, presence of ribosomes and DNA.
1. Since they have specialised cells, they are able to carry out different functions. Not every cell has to carry out every metabolic function in a multicellular organism
2. specialized cells are the centerpiece of why organism are able to survive and adapt to their environment. without specialty cells, there would be no muscle tissue or brain material .
