A Quote by Keith L. Moore
This fertilized ovum, known as a zygote, is a large diploid cell that is the beginning, or primordium, of a human being.

A zygote is the beginning of a new human being (i.e., an embryo).
Although life is a continuous process, fertilization is a critical landmark because, under ordinary circumstances, a new, genetically distinct human organism is thereby formed.... The combination of 23 chromosomes present in each pronucleus results in 46 chromosomes in the zygote. Thus the diploid number is restored and the embryonic genome is formed. The embryo now exists as a genetic unity.
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.
Plants are decisive to a fault. A stem produces a bud that flowers once and once only. It offers pollen that is either dispersed or goes nowhere. One pollen grain either enters a stigma or it falls upon stony ground. An ovum is either fertilized or the whole project stalls out.
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.
A battery by definition is a collection of cells. So the cell is a little can of chemicals. And the challenge is taking a very high-energy cell, and a large number of them, and combining them safely into a large battery.
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.
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.
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
Every cell in our body, whether it's a bacterial cell or a human cell, has a genome. You can extract that genome - it's kind of like a linear tape - and you can read it by a variety of methods. Similarly, like a string of letters that you can read, you can also change it. You can write, you can edit it, and then you can put it back in the cell.
As with most animal eggs, the early events of amphibian development are largely independent of the environment, and the processes leading to cell differentiation must involve a redistribution and interaction of constituents already present in the fertilized egg.
The uniformity of the earth's life, more astonishing than its diversity, is accountable by the high probability that we derived, originally, from some single cell, fertilized in a bolt of lightning as the earth cooled.
Upon the union of the male germ cell with the female egg cell, a new cell is created which almost immediately splits into two parts. One of these grows rapidly, creating the human body of the individual with all its organs, and dies only with the individual.
The importance of the egg's non-nuclear material - the cytoplasm - in early development is apparent in the consistent relation that is seen to exist between certain regions in the cytoplasm of a fertilized egg and certain kinds or directions of cell differentiation.
I didn't know how to deal with real life issues the right way as a humble human being until I was humbled to the point of being put in a jail cell.
I believe in recognizing every human being as a human being--neither white, black, brown, or red; and when you are dealing with humanity as a family there's no question of integration or intermarriage. It's just one human being marrying another human being or one human being living around and with another human being.
