Cellular Structure Quotes

Protoplasm, simple or nucleated, is the formal basis of all life. It is the clay of the potter: which, bake it and paint it as hewill, remains clay, separated by artifice, and not by nature from the commonest brick or sun-dried clod.

And you are made of a hundred trillion cells. We are, each of us, a multitude.

The beauty of a living thing is not the atoms that go into it, but the way those atoms are put together. Information distilled over 4 billion years of biological evolution. Incidentally, all the organisms on the Earth are made essentially of that stuff. An eyedropper full of that liquid could be used to make a caterpillar or a petunia if only we knew how to put the components together.

The human body is the most complex system ever created. The more we learn about it, the more appreciation we have about what a rich system it is.

If I brought you down to the size of an individual cell so that you could see your body from that perspective, it would offer a whole new view of the world. When you looked back at yourself from that perspective you would not see yourself as a single entity. You would see yourself as a bustling community of more than 50 trillion individual cells.

Every cell is a triumph of natural selection, and we’re made of trillions of cells. Within us, is a little universe.

I have divers times endeavoured to see and to know, what parts the Blood consists of; and at length I have observ'd, taking some Blood out of my own hand, that it consists of small round globuls driven through a Crystalline humidity or water.

A cell is a complex structure, with its investing membrane, nucleus, and nucleolus.

A cell is regarded as the true biological atom.

Molecular biology has shown that even the simplest of all living systems on the earth today, bacterial cells, are exceedingly complex objects. Although the tiniest bacterial cells are incredibly small, weighing less than 10-12 gms, each is in effect a veritable micro-miniaturized factory containing thousands of exquisitely designed pieces of intricate molecular machinery, made up altogether of one hundred thousand million atoms, far more complicated than any machine built by man and absolutely without parallel in the nonliving world.

It was a reaction from the old idea of "protoplasm", a name which was a mere repository of ignorance.

Biology sometimes reveals its fundamental principles through what may seem at first to be arcane and bizarre.

We finally understand in general terms how a cell is organized, how its specialized organs function in a well integrated manner to insure its survival and replication.

From the physical point of view, a man is nothing more than a system of cells, or from the mental point of view, than a system of representations; in either case, he differs only in degree from animals.

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.

Next it was found that it was physiologically and structurally the same in the plant, that it was the living part of the plant, that which manifested the life and did the work in vegetable as well as in animal organisms.

You contain a trillion copies of a large, textual document written in a highly accurate, digital code, each copy as voluminous as a substantial book. I'm talking, of course, of the DNA in your cells.

The hand of the Creator is actively involved in every atom, every plant, every creature, and yourself, in every cell in your body.

Passing just lately over this lake, ... and examining this water next day, I found floating therein divers earthy particles, and some green streaks, spirally wound serpent-wise, and orderly arranged, after the manner of the copper or tin worms, which distillers use to cool their liquors as they distil over. The whole circumference of each of these streaks was about the thickness of a hair of one's head. ... all consisted of very small green globules joined together: and there were very many small green globules as well. [The earliest recorded observation of the common green alga Spyrogyra.]

A hydrogen atom in a cell at the end of my nose was once part of an elephant's trunk. A carbon atom in my cardiac muscle was once in the tail of a dinosaur.

The idea of protoplasm, which was really a name for our ignorance, [is] only a little less misleading than the expression "Vital force".

The body is a community made up of its innumerable cells or inhabitants.

In order to understand the phenomena in a certain plasma region, it is necessary to map not only the magnetic but also the electric field and the electric currents. Space is filled with a network of currents which transfer energy and momentum over large or very large distances. The currents often pinch to filamentary or surface currents. The latter are likely to give space, as also interstellar and intergalactic space, a cellular structure.

A tree is an aerial garden, a botanical migration from the sea, from those earliest plants, the seaweeds; it is a purchase on crumbled rock, on ground. The human, standing, is only a different upsweep and articulation of cells. How treelike we are, how human the tree.

In reality, a cell is a biological mini-me compared to the human body. A cell has every biological system that you have.
