list three characteristics specific to each: prokaryotes and eukaryotes.

Answer: The characteristics of prokaryotic cells are:

• Membrane bound cell organelles such as Mitochondria, Golgi apparatus, Chloroplasts are absent.
• A membrane bound well defined nucleus is absent.
• Genetic material is circular DNA and occurs naked in the cell cytoplasm. It is attached to the cell membrane and called nucleoid.
• The cell size ranges from 0.1 to 5.0 micrometre in size.
• The cell wall is a rigid structure which is made up of polysaccharides.

The features of eukaryotic cells are as follows:

Eukaryotic cells have the nucleus enclosed within the nuclear membrane.

The cell has mitochondria.

Flagella and cilia are the locomotory organs in a eukaryotic cell.

A cell wall is the outermost layer of the eukaryotic cells.

The cells divide by a process called mitosis.

The eukaryotic cells contain a cytoskeletal structure.

The nucleus contains a single, linear DNA, which carries all the genetic information.
