Aspects of Cells
- Homeostasis - The property of either an open system or a closed system, especially a living organism, that regulates its internal environment so as to maintain a stable, constant condition.
- Life - A condition of growth through metabolism, reproduction, and the power of adaptation to environment through changes originating internally.
- Microscopic - The scale of objects, like cells, that are too small to be seen easily by the naked eye and which require a lens or microscope to see them clearly.
- Unicellular - Organisms which are composed of only one cell.
- Multicellular - Organisms consisting of more than one cell, and having differentiated cells that perform specialized functions.
- Tissues - A collection of interconnected cells that perform a similar function within an organism.
- Cellular differentiation - A concept in developmental biology whereby less specialized cells become a more specialized cell type in multicellular organisms.

Famous quotes containing the words aspects of, aspects and/or cells:
“That anger can be expressed through words and non-destructive activities; that promises are intended to be kept; that cleanliness and good eating habits are aspects of self-esteem; that compassion is an attribute to be prized—all these lessons are ones children can learn far more readily through the living example of their parents than they ever can through formal instruction.”
—Fred Rogers (20th century)
“Grammar is a tricky, inconsistent thing. Being the backbone of speech and writing, it should, we think, be eminently logical, make perfect sense, like the human skeleton. But, of course, the skeleton is arbitrary, too. Why twelve pairs of ribs rather than eleven or thirteen? Why thirty-two teeth? It has something to do with evolution and functionalism—but only sometimes, not always. So there are aspects of grammar that make good, logical sense, and others that do not.”
—John Simon (b. 1925)
“They are sworn enemies of lyric poetry.
In prison they accompany the jailer,
Enter cells to hear confessions.
Their short-end comes down
When you least expect it.”
—Charles Simic (b. 1938)
