1. 1.2 Ultra structure of cells
1. Pick up your science journal.

2. Microscope sketching techniques
All drawings must be done in pencil only
Use distinct single lines when drawing. No sketching.
Use stippling (dots) to illustrate darker areas. No shading.
Label important features of the specimen.
Be sure to include scientific name of the specimen, in correct notation, if appropriate.

3. 1.5 Limitations to the cell theory
Striated muscle fibers: multi-nucleated, long (30 mm)
Fungal hyphae: multi-nucleated
Giant algae (Acetublaria): large (100 mm)
Viruses: living or not?

4. 1.2 Relative cell size molecules: ~ 1 nm
cell membrane thickness: ~ 10 nm
viruses: ~ 100 nm
bacteria: ~ 1 µm
organelles: up to 10 µm
eukaryotic cells: up to 100 µm

5. Cell Organelle Review Game
Match the organelle with the definition.
Some of the organelles are for prokaryotes whereas others are for eukaryotes.
Draw a picture of the organelles in both cell.

6. 1.2 Ultra structure of cells
1. Pick up your science journal.

7. 1.2 Light vs. Electron Microscopes
Easy preparation of sample
Complex preparation of sample
Living material can be examined
Living material cannot survive inside the vacuum of the electron microscope
Color images
Monochrome images
Large field of view
Small field of view
Poor resolution + magnification
Good resolution and magnification

8. Cell Organelles Activity
On the poster provided, draw a diagram of a prokaryotic and eukaryotic cell, including all the labels and functions of appropriate organelles.
