Cells & Organelles:

• Animal cells and plant cells

ANIMAL CELLS: NUCLEUS, CYTOPLASM, CELL MEMBRANE

PLANT CELLS: NUCLEUS, CYTOPLASM, CELL MEMBRANE, CELL WALL, CHLOROPLASTS & VACUOLE

Cells & Organelles:

• NUCLEUS: The brain of the cell, contains DNA.
• CYTOPLASM: The jelly filling of cell, contains water and nutrients.
• CELL MEMBRANE: The soft flexible wall around a cell, controls what goes in and out.
• CELL WALL: A hard outer wall made of cellulose, it for protection and support.
• CHLOROPLASTS:Little green balls in cells that can do photosynthesis.
• VACUOLE: An extra balloon in a cell that can contain nutrients or colours.

Learning how to do Research
Microscope.  (p. 137-143)

 Read 'Parts of the Microscope' and 'Preparation'

- Make 1 t/m 3 (p. 139-140)

- Try to memorize the parts of the microscope

(     )

(              ) 

=large knob

=small knob

microscope steps       

1. put slide under microscope
2. turn the smallest objective (4x)
3. put on the light
4. use large knob to focus
5. turn larger objective (10x)
6. use small knob to focus!!
7. turn objective to 40x
8. use small knob to focus!!

Always be careful with the microscope

- lift on the arm, one hand underneath the base

Cleaning up:

- Turn nosepiece away

- lower the stage

Have you memorized the parts of the microscope?

Which part do you look through?

1. Ocular lens
2. Base
3. Body tube
4. Light source

What is the magnification when the ocular lens magnifieks 10x and the objective 40x?

1. 50x
2. 400x
3. 40x
4. 500x

Which knob do you first turn to focus?

1. The small knob
2. The light source
3. The diaphragm
4. The large knob

microscope

1. put slide under microscope
2. turn the smallest objective (4x)
3. put on the light
4. use large knob to focus
5. turn larger objective (10x)
6. use small knob to focus
7. turn objective to 40x
8. use ONLY small knob to focus!
9. turn largest objective (40x)
   
10. use ONLY small knob to focus!!!!

slide

- slide = a small piece of glass

- put the specimen on the glass

-add a drop of water or colour

- put a cover slip on top

Practicum 1 op pagina 145

- Haal een microscoop en preparaat, stel scherp op 40x 

- Maak een foto door de oculair, laat deze aan de docent zien

- maak de tekening op p. 145

- Maak practicum 3 af op pagina 146 (tekening van krantenletter) denk aan

natuurgetrouw, vergroting, titel, etc.

Stuur foto in van de tekening van je krantenletter (pagina 146)

Preparaat + tekening haren (practicum 4)

1. Microscoop klaarzetten (kleinste vergroting = 40x) 
2. Haar bij elkaar uittrekken of knippen
3. Preparaat en plakband halen
4. Haar gekruisd op de 'slide' leggen en vastplakken met plakband
   
   
5. Scherpstellen met grote schroef, maak een foto
6. Naar 100x vergroting, met kleine schroef scherpstellen
