|
Term
|
Definition
| The nucleoid consists of a single chromosome (loop of DNA) found in prokaryotic cells. It is not a true nucleus because it does not have a membrane. |

| Why are most cells small? |
|
Definition
| Cells are small so that the volume to surface area ratio is adequate for a cell to exchange materials with the environment. Small cell = more surface area per volume. Large cell = less surface area per volume. |

Term
| What is the difference of an SEM and a TEM? |
|
Definition
An SEM is the picture obtained from a Scanning Electron Microscope. It provides a 3D surface view of specimen. The sample is coated with a thin layer of metal which gives off secondary electrons. The SEM produces a TV-like picture on a screen.
A TEM is a picture obtained from a Transmission Electron Microscope. Electrons--focused by a set of magnetic lenses--pass through a specimen, and an image is projected onto a fluorescent screen or photographic film. Images show greater detail (50,000x, distance to distinguish two points = 2 nm) but the specimen must be dried out for viewing. |
