A Quote by Lewis Thomas
It is not a simple life to be a single cell, although I have no right to say so, having been a single cell so long ago myself that I have no memory at all of that stage of my life.

Although each egg cell produced by a woman carries a single X chromosome, the sperm cells produced by a man carry either an X or a Y. This means, in very simple terms, that the sperm cell determines a baby's sex.
What we expect to find, certainly in our own solar system, are probably simple single or multiple-cell forms of life. To get to intelligent life takes stability of conditions over huge, long periods of time.
Of all created things the source is one, Simple, single as love; remember The cell and seed of life, the sphere That is, of child, white bird, and small blue dragon-fly Green fern, and the gold four-petalled tormentilla The ultimate memory. Each latent cell puts out a future, Unfolds its differing complexity As a tree puts forth leaves, and spins a fate Fern-traced, bird feathered, or fish-scaled.
In science there is something known as a stem cell. A stem cell is an undifferentiated cell which has not yet decided whether it's gonna be a cell of your brain or a cell of your heart or of your finger nail. But science is learning how to coax, how to manipulate, the raw material of life that we call stem cell to become any cell of the body. I think that God is the stem cell of the universe.
A stem cell is essentially a blank cell capable of becoming another, more differentiated cell-type in the body, such as a skin cell, a muscle cell or a nerve cell.
It is easy to make out three areas where scientists will be concentrating their efforts in the coming decades. One is in physics, where leading theorists are striving, with the help of experimentalists, to devise a single mathematical theory that embraces all the basic phenomena of matter and energy. The other two are in biology. Biologists-and the rest of us too-would like to know how the brain works and how a single cell, the fertilized egg cell, develops into an entire organism
My father, David Gilbert, is in prison in New York. He is lucky that he has a single cell, not shared with another person. His cell is about eight feet by eight feet.
Omnis cellula e cellula," he said again. "All cells come from cells. Every cell is born of a previous cell, which was born of a previous cell. Life comes from life. Life begets life begets life begets life begets life.
We dwell in the house of the body, but its perfection and intricate life are the work of a wisdom which never relaxes dominion over a single cell.
Cell genetics led us to investigate cell mechanics. Cell mechanics now compels us to infer the structures underlying it. In seeking the mechanism of heredity and variation we are thus discovering the molecular basis of growth and reproduction. The theory of the cell revealed the unity of living processes; the study of the cell is beginning to reveal their physical foundations.
If you go back to the first single-cell form of life, it clearly possessed the capacity to receive, to utilize, to store, to transform, and to transmit information.
If a single cell, under appropriate conditions, becomes a man in the space of a few years, there can surely be no difficulty in understanding how, under appropriate conditions, a cell may, in the course of untold millions of years, give origin to the human race.
Every single cell in your body is affected by every single thought that you have.
In families you can find the source of every human drama. It is interesting because the cell of a society, the cell of a country, the cell of humanity - everything lies in the family.
To date, embryonic stem cell research has not produced a single medical treatment, where ethical, adult stem cell research has produced some 67 medical miracles.
Just like a single cell, the character of our lives is determined not by our genes but by our responses to the environmental signals that propel life.
