cell. Prokaryotic cells do not have a nucleus as they have different organelles to eukaryotic cells. The only organelle common to eukaryotic cells are the ribosomes (Fig. 6.3). However, the ribosome of a eukaryotic cell is rather different in size and structure to that of a prokaryotic cell...
2.Cytoplasm– It refers to the fluid found inside the plasma membrane which constitutes a few cell organelles. 3.Genetic Material– Double-stranded and circular DNA is the genetic material that isly suspended in the cytoplasm or attached to the cell membrane at some points without a nuclear cove...
salts, an assortment of organic molecules and the cell's organelles. In this medium, a number of chemical reactions can take place. If you imagine a water balloon filled with a mixture of water and shaving cream being a cell, the rubber represents...

Prokaryotic cells have their genetic material present in a single chromosome within a central region of the cell's cytoplasm called the nucleoid. The cytoplasm of a cell is made up of semifluid mass called cytosol which surrounds intercellular structures called organelles. Unlike some of the organel...

Of all the types of cells revealed by the microscope,bacteria have the simplest structure and come closest to showing us life stripped down to its essentials.Indeed,bacteria contain essentially no organelles (recognizable substructures)-not even a nucleus to hold their DNA.This property-the presence...
The main difference between the two types of cell is thatprokaryotic cells have no (membrane-bound) organelles. This means that the processes that usually happen in organelles take place in the cytoplasm. The DNA in prokaryotes is circular, whereas DNA in eukaryotes is linear and arranged in ch...
Prokaryotic organisms have varying cell shapes. The mostcommon bacteria shapesare spherical, rod-shaped, and spiral. Using bacteria as our sample prokaryote, the following structures andorganellescan be found in bacterial cells: Capsule:Found in somebacterialcells, this additional outer covering protects...
