Difference Between Prokaryotic and Eukaryotic Cell

image of Eukaryotic and Prokaryotic Cell

On the basis of internal structure, cells are of two types: Prokaryotic and Eukaryotic cells. Prokaryotic cells are simple and small in size while eukaryotic cells are complex and large in size. Eukaryotic cells have true nucleus and nucleolus with different types of membrane-bound cell organelles such as Endoplasmic reticulum, Golgi body, Mitochondria etc. Well … Read more

Difference Between Mitochondria and Chloroplast

The cell is the functional, structural and biological unit of all living organisms. It is of two types such as prokaryotic and eukaryotic cells. The cell contains many types of organelles, among them, some are typically solitary such as the nucleus and golgi complex, while others can be numerous such as mitochondria,  lysosomes, chloroplasts, etc. … Read more

Ribosome: Types, Structure and Functions

The ribosome is one of the essential membrane-bound organelles of the cells. It has tiny sphere-shaped structure. It contains protein and ribose nucleic acid (RNA) and provides space for protein synthesis.  It is found in the cytoplasm, mitochondrial matrix, and chloroplast. It is also found on the outer membrane of ER (endoplasmic reticulum) and nucleus. … Read more

Lysosome and Its Functions

Lysosomes are single membrane-bound cytoplasmic organelles of most cells filled with a wide variety of hydrolytic enzymes that are involved in intracellular digestion.  The term “Lysosome” comes from the Greek word ‘lysis’, to separate and ‘soma’ body.  Sometimes it can be described as the stomach of the cell. In 1950, Belgian Cytologist Christian Rene de … Read more

Plastid : Types, Structure and Functions

Plastids are the cytoplasmic organelles which are associated with the special metabolic process of the plant cells. It is the second largest organelle of the cell which is bounded by a double unit membrane and may be colored or colorless. Mayer and Schimper first used the term plastid. Plastids are found in plant cells and … Read more

Endoplasmic Reticulum : Structure and Functions

All living organisms are composed of cells and cell products. Each eukaryotic cell contains several cytoplasmic organelles. Among the organelles, endoplasmic reticulum performs as intracellular transport system for various substances and also helps to exchange the materials between nucleus and cytoplasm.  Prokaryotic cells and RBC (red blood cell) do not have any endoplasmic reticulum.Endoplasmic reticulum … Read more
