The Endoplasmic Reticulum (ER) forms an interconnected network of tubules, vesicles and sac-like structures called cisternae within the cells. It is a part of the endomembrane system which consists of the plasma membrane of the cell, the nuclear envelope, etc….

Ever since Robert Hooke first observed cork cells in 1665, biochemistry as well as our understanding for cells and genetics has come a very long way. In 1984 when the first brick’ cell phones were just coming out, who would…

Apoptosis is a suicide/evacuation plan that allows living cells to die with dignity, for the good of the organism. Sometimes cells must be broken down and absorbed by the system, without harm to healthy tissue. Apoptosis helps to maintain homeostasis…

The Golgi apparatus (also known as the dictyosome or Golgi body) is a cellular organelle that is to be found in many eukaryotic cells. Their main job is as a processing and packaging factory for the important macromolecules vital to…

Nucleus is the central processing unit of the cell. It is called the brain of the cell. Using the same analogy, just like the brain stores all the information about our body and life, and facilitates the bodily functions centrally,…

In eukaryotic cells, such as human cells, for example, the cell nucleus is the important organelle that houses the chromosomes. The chromosomes are the store of most of the genetic material of the cell (bar the mitochondrial DNA which is…

Mitochondria are the power houses’ of the cell. Their main job is to produce energy required for the functioning of our cells. They are double membrane structures, and their shape and number varies depending on the cell type. Their membranes…

Enzymes are the catalysts or chemical substances synthesized in living cell and responsible for metabolic activities within the organism. Subatances which react with the help of enzymes are called “Substrates” and materials produced as the result of a chemical reaction…

The Golgi apparatus or the Golgi complex is a series of unconnected cup-shaped structures called cisternae which are bound to the membrane. It was first discovered by an Italian physician Camillo Golgi in 1898 and then named after him. Usually,…

Ribosomes are a cellular component, that are not considered to be a true organelle because they lack a membrane, but are often referred to as a non-membranous organelle. They are found in the cytoplasm and are made of ribosomal RNA…
