Cells, essay on cells, the building blocks of the human body, contain genetic information DNA that is passed on from parent cell to daughter cell through the cell reproduction process called cell division.
When a cell divides the genetic information contained in DNA copies itself and transmits to a daughter cell through a series of processes. There are two types of cells: eukaryotic and prokaryotic and these two cell types reproduce or divide in two main ways, either Mitosis or Meiosis, essay on cells.
Cell division can also be broken down into two reproductive categories: asexual Mitosis and sexual Meiosis. Solomon et al Every cell contains DNA, which is in fact the vital information genetic code needed to construct and maneuver a human body, essay on cells.

Human beings usually have 46 different chromosomes; other species can have as little as 2 chromosomes or as many as Most species contain between 10 and 50 chromosomes.
When cells reach maturity, they must either stop growing and remain as they are, or divide and reproduce themselves. Some cells like the nerve and muscle cells in the human body don't divide but stay the same as they reach maturity, this makes them rarer and more finite. Other cells divide when they reach maturity through the Mitosis or Meiosis types of cell division, essay on cells.
The cells that do divide do so in what is called the cell cycle, the cycle of a cell life from one division to the next. A cell cycle from one division to the next is also called a generation as it is with human beings essay on cells one set of parents to the children, essay on cells.

Multipotent cells like adipose-derived stem cells have not yet differentiated, giving them many diverse uses for matured adults. Stem cells are non-differentiated cells and luckily have the ability to self-renew. Stem cells remain undifferentiated, so that, there will be a cache of undifferentiated cells to repair damaged tissue, essay on cells. Embryonic stem cells can be grown in a laboratory from blastocysts and made to differentiate into nerve, liver, muscle, blood, essay on cells, and other cells.
Opponents claim that since the cells come from an embryo, these "cells are alive and extracting these cells means the death of a living organismwhich is immoral" [Wes99].
