What is cell differentiation?
By: Marion Garcia
What is cell differentiation? At conception human cells are produced and begin to divide. These cells contain all the genes that the body needs to grow, develop, and carry out the different functions of the body. The process in which the cells develop into...
Would stem cell research be responsible for taking or saving a life?
By: Molly McGreevy
The debate over stem cell research is largely centered on human embryonic stem cells. These are cells taken from the inner mass of a blastocyst, usually in the first five to seven days following fertilization. These cells are called pluripotent because they have the...
The structure and function of kidney cells
By: M. J. Joachim
Understanding Kidneys Mammals are made up of millions of cells, each containing cytoplasm and a nucleus surrounded by a membrane. Together these cells make up all of our being including blood, bone, and organs. Each organ has a purpose, and one of the main purposes...
Amino acids and their structure and function
By: Louis Rosenfeld
Amino acids, the building blocks of proteins, are composed of a central carbon atom to which is attached an amino group (-NH2) and an acid group (carboxylic acid: -COOH); hence their name. All carbon atoms have four bonds. Besides the amino group and acid group...

The two principal functions of muscles are to produce movement and to maintain posture. Muscle tissues have the ability to shorten or contract. Because a muscle cell's length is much greater than its width, they are frequently referred to as muscle fibres. There are three...

No one is yet certain how multicellular life evolved. There are three prominent theories about how it happened, with one a strong favorite among scientists. Symbiosis Throughout the world, many organisms live in symbiosis. Symbiosis is an association of two different species that may (though...
How cells migrate in the embryo
By: Faust Gravier
As a mother of one, I felt many different sensations in my expanding belly that were indescribable. I can not say for sure that a woman can feel the cell migration,but feeling the baby's movements,for me,makes up for not having that knowledge...
The structure and function of liver cells
By: Kaush J
The liver is the largest internal organ of the body, weighing about 1.36Kg, located in the right upper quadrant of the abdomen. It consists of two major lobes (left and right) and two minor lobes (caudate and quadrate). The liver is involved in...
What are prokaryotic and eukaryotic cells?
By: Jerges Cervantes
We are all of us, each and every lifeform on the planet, made up of thousands upon millions of cells. The cell is the basic structural and physiological unit of all living organisms on the planet. However, while all life is made up of cells...
By: Wendy R.
All living things on Earth are made up of cells. These cells can be either Prokaryotic or Eukaryotic in nature.There are many similarities in these two types of cells, including the fact that they were probably derived from similar ancestors. Prokaryotes are usually...
