Slide 1 - Tekstslide

Why do plant cells have chloroplasts?

Slide 2 - Open vraag

What do eukaryotes have that prokaryotes do not?
DNA
Cell membranes
Cell wall
Nucleus
Ribosomes

Slide 3 - Poll

Mitochondria
Respiration takes place here. Generating energy for cellular activities.
Nucleus
Controls the functions of the cell. Contains the D.N.A
Cytoplasm
Where cellular reactions take place. 
Ribosomes
This is the site of protein synthesis.
Cell membrane
This controls the movement of substances in and out of the cell.
Cell wall
This provides structure and protection for the cell. Present in plant and bacterial cells.
Plasmid
This is an additonal circular piece of DNA that can transfer genetic material from one cell to another. 
String of DNA
DNA is not contained in a nucleus but is wound in a loop. 

Slide 4 - Tekstslide

Contains the DNA, controls the cell.
Absorbs energy from sunlight to use in photosynthesis. 
Controls which materials can come into and out of the cell
Supports and protects the cell. Also found in bacterial cells.
Provides energy for the cell from respiration of glucose.
Contains the cell sap.
Where cellular reactions take place.

Slide 14 - Tekstslide

Tell me 4 facts about Enzymes.

Slide 15 - Woordweb

Enzymes are....
Catalysts
Biological catalysts
Chemical substrate

Slide 16 - Poll

Enyzmes are biological                      . They                     the rate of a reaction without being used up in the process. Each enzyme is                      to one substrate as only that substrate's shape fits the enzyme's                                .
catalysts
increase
decrease
specific
active site
reaction
inactive
