Mitochondria

Because these organelles are responsible for providing the most of the ATP the cell needs, they are often referred to as the "powerhouses" of the cell. They are often the:

C. interphase

DNA replication occurs during: A. cytokenesis B. interphase C. metaphase D. prophase

the structural & functional unit of all living things, a complex entity

Define Cell.

interphase

During ________ the cell grows & performs its usual activities.

A - with a paper towel B - with soap and water C - with special lens paper and cleaner C - with special lens paper and cleaner

How do you clean the lenses of your microscope?

6

How many stages in Mitosis are there?

10x x 35x = 350x

If the ocular lens magnifies a specimen 10x, and the objective lens used magnifies the specimen 35x, what is the total magnification being used to observe the specimen? _____________

Ribosomes

Proteins are assembled on these organelles

Stage

The microscope slide rest on the ______

Selective Permeability

The plasma membrane not only provides a protective boundary for the cell but also determines which substances enter or exit the cell. We call this characteristic:

False

True of False. All animals have a cell wall

FALSE - w/ objective lens

True or False? You should always begin observation of specimens with the oil immersion lens

False

True/False. The end product of mitosis is four genetically identical daughter nuclei.

Chromatin

When a cell is not dividing, the DNA is loosely spread throughout the nucleus in a threadlike form called

A - the specimen is clearly is focus at this depth. B - the slide should be almost in focus when changing to higher magnifications C - you can easily discriminate two close objects as separate B. slide should be almost in focus when changing to higher magnifications

Your lab microscope is "parfocal." What does this mean?
