Make a picture of practical 5 (blz. 147)

Reflectie: Wat vinden jullie ervan

- interessanter dan Thema 1 

- lastig om verschil tussen cel en weefsel aan te wijzen

- benieuwd naar microscopie

Basic 2.4 Cells

1. Know and recognize important organelles (organs of the cell) 
   
   
2. Know the difference between plant and animal cells

- organisme

- organenstelsel

- orgaan

- cel

Biopagina: 

         cel, weefsel, orgaan, orgaanstelsel of organisme?

What type of cells are photographed trough the microscope here?

1. Animals cells
2. Plant cells
3. Bacteria
4. Fungal cells (schimmel)

Cells

Some are round, others are oval or shaped like a star. 

Even if their shape differs, they have the same parts!

Animal cells

(kernplasma) -

• --  assignment 2.
  (proteins = eiwitten in membraan, die als poortje en pompjes om belangrijke stoffen te vervoeren) 

Cheek lining cells (=wangslijmvliescel)

- (extracellular matrix)

Plastids

 (=korreltjes)

• Function of plastids?  (DDU)
• Fotosynthesis -> aantrekkelijkheid/rijpheid / opslag zetmeel

Belangrijkste plastide voor planten? 

Chloroplast        -->         Fotosynthese          
(suiker maken met zonlicht,
O2 komt als restproduct vrij)

Checklist for Theme 2 with extra practice link (in Dutch)

Example

R - Right here is an important part of my body. My subject (this bone) is part of my rib case. 

I - It's something that protects your heart and your lungs.

B - besides being part of your bone system, it is also an organ

Send in your small poem to pay homage to an organ/organelle. In this way:
H - Here in my body......
E - Everyday it pumps to keep me alive
A - All the love is stored in here....
R - Right in the middle of my chest, or maybe a bit to the left
T - Thank you strong heart for beating my warm blood into my aorta!
