CELL THEORY- EQ: What are the 3 facts of the cell theory? - pp191

1. All living organisms are made up of cells

2. The cell =basic unit of life

3. All new cells come from existing cells

EQ- Which Scientists are connected to cell discovery? - pp190-191*Robert Hooke-discovered cells look like prison cells in a cork.

Hooke used a light compound microscope to examine the cells

*Mathias, Schwann and Virchow put the cell theory together

EQ: How do microscopes differ? pp191-193

EQ: Compare images, magnification, color, how it works, what can be seen, what can

it be used for.

LIGHT COMPOUNDS MICROSCOPE ELECTRON MICROSCOPE

1. Samples must be alive Non Living samples

2.Color images Black + white images

3.Magnification x1000 to 1500Can be used to see organisms up to 1 millionth of meter but resolution is not as high and clear.

Magnification x500,000 , clearer, higher resolutionCan be used for tiny specimens under 1 millionth of meter up to 1 billionth)

4. Cannot see inside cell Transmission2DSamples must be thinCan see inside of cell-structures

Scanning3DThick samplesCan see only surface of cell

EQ: Differences between PROKARYOTIC (P) and EUKARYOTIC (E) CELLS pp193-4

*In E-Cells = parts are membrane bound like cell membrane + nuclear membrane surrounding the nucleus

E-Larger, more complex, DNA is contained in nucleus

*P-Cells = simpler, smaller, no nucleus, DNA scattered,

parts are not bound by membranes. P cells have a cell wall, cell membrane + ribosomes, scattered DNA pp207

EQ: Describe the CELL’s BOUNDARIES. pp203-4

1.Cell Membrane (aka: Plasma Membrane)

• This is called the “Fluid Mosaic Model” of the plasma membrane• The cell membrane is semi-permeable = selectively allowing

some substances to pass through it and rejecting some• It is made up of 2 layers of lipids (aka: lipid bilayer)

2. Cell Wall = found in plants maintain shape, support and structure.
