Would stem cell research be responsible for taking or saving a life? Stem cell research has never taken a life, nor is it expected to in the near future. There is a great deal of misunderstanding, misinformation, and mystery surrounding stem cell research in the...
Mitochondria defined
By: Jeffrey Graf
The mitochondria are organelles located with each cell. The mitochondria are bacillus shaped, or shaped like a drug capsule. In the fact that they are shaped like many common bacteria is not a coincidence. An important aspect of the mitochondria is called the endosymbiotic theory...
Biological explanation of the endoplasmic reticulum
By: Rohit Kulkarni
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. apart from the ER. It...
Ribosomes: an explanation
By: Rohit Kulkarni
Ribosomes are the protein factories in our cells. The way things work in a cell mean that the DNA codes for specific sequences of amino acids in various proteins, and these proteins, on appropriately folding are responsible for various activities and functions of the cell...
Mitochondria defined
By: Rohit Kulkarni
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 are composed of phospholipid bilayer...
Biology: The Golgi apparatus
By: Rohit Kulkarni
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, there is only one Golgi...
The cell nucleus
By: Rohit Kulkarni
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, nucleus stores the information about...
