Chapter 2/6 Test Flashcards
- Golgi Apparatus
Membrane forms large sacs for storage and packing of cell’s secretions.
Receives protein from ER.
Warehouse of cell.
- Nucleolus
Storage area for RNA
Makes ribosomes
- Nucleus
Control centre
Has DNA
- Lysosome
Releases enzymes
- ER
E: Makes protein
R: Transports protein
- Cell Membrane
Controls what goes in and out
- Mitochondrion
Powerhouse of cell
Makes energy
- Cytoplasm
Liquid where organelles are
- Centriole
Control mitosis (cell division)

Magnification Lab
Field Diameter:
Low = 4500 Medium = 1800 High = 450
Drawing x 10,000 = D0,000

Actual Actual • Across
——–
How many across
Hypothesis
An educated guess written in the “if… then…”
A good hypothesis has 3 points:
•Explanatory
•Testable
•Predict
Microscope
2 ways to magnify:
•Electron: Uses electrons to hit object at maximum mag. 1,000,000
A) TEM have to be dead since they’re sliced into thin wafers
B) SEM are living, see the surface in 3D picture
•Optical: Uses light 1000x
Levels of Cell Organization
Atom, molecules, cell, tissue, organ, etc.
Organic
All living things have carbon, therefore they’re organic.
Inorganic
No carbon
Ex: water, salt
Cell Theory
- All living things are composed of cells
2. All cells arise from other cells
If something is living they do the following:
•Grow
•Reproduce
•Move
•Respond to Stimuli
•Metabolism - a) anabolism: synthesis
b) catabolism: degrade
- Repair and Maintenance
- Other
Diffusion of Cell Membrane
Movement of molecules from area of high to low concentration
Osmosis
Diffusion of water. Causing cell to shrink or swell
Types of Situations (Cell Membrane):
- Isotonic - Same size
- Hypertonic - Shrink and lose H2O
- Hypotonic - Swell and gain H2O
