The Test will cover the following concepts and terms:

1. Observations and Inferences: Definitions and examples

2. Parts of the Microscope: (How to use it-lab-separate part of test)

Terms: microscope (know how to use it to view objects on slides)

wet mount (how to make one),

cover slip (what is it used for?),

total magnification (how to calculate it-lens x objective),

objective lens (types and what they do)

3. Cell Theory: 6 tenets of Cells: (Who first proposed them?)

* All known living things are made up of cells.

* The cell is structural & functional unit of all living things.

* All cells come from pre-existing cells by division. (Spontaneous Generation does not occur).

* Cells contain hereditary information which is passed from cell to cell during cell division.

* All cells are basically the same in chemical composition.

* All energy flow (metabolism & biochemistry) of life occurs within cells

4. Life Processes (6-what makes something alive, what ALL living things do)

* Take in nutrients/energy

* Use energy

* Grow

* Reproduce

* Produce wastes

* Respond to environment

5. Animal Cell Organelles/Function

a. cell membrane -the thin layer of protein and fat that surrounds the cell.

b. centrosome -a small body located near the nucleus microtubules are made.

c. cytoplasm -the jellylike material outside the cell nucleus in which the organelles are located.

d. Golgi body -(also called the Golgi apparatus or Golgi complex) a flattened, layered, sac-like organelle that looks like a stack of pancakes. It packages proteins and carbohydrates into membrane-bound vesicles for "export" from the cell.

e. lysosome -(also called cell vesicles) round organelles surrounded by a membrane and containing digestive enzymes. This is where the digestion of cell nutrients takes place.

f. mitochondrion -spherical...
