3. This is not a cell of a bacterium
4. This is not an animal cell

The scientific name of a dog is: Canis lupus familiaris
The scientific name of a grey wolf is: Canis lupus

What does this tell you about these animals?

You see a picture of a cell.
The cell has a vacuole
What is the right conclusion?

1. This is either plant or animal
2. This is either plant or bacterium
3. This is either plant or fungi
4. This is either animal or fungi

You see a picture of a cell.
The cell has a cell membrane
What is the right conclusion?

1. This is either plant or animal
2. This is either bacterium or animal
3. This is either fungi or plant
4. This could be any organism

There are more different kingdoms than phyla

1. Right
2. Wrong

Characteristics of Bacteria

Bacteria are unicellular

They come in different shapes: rods, spheres, spirals

All bacteria cells have:

• NO nucleus (they do have DNA)
• Cell wall

Uni = 1 cellular = cells

The entire organism consists out of one cell

You don't need to learn all parts of this cell.

Only that:

It has no nucleus,

It has a cell wall

Reproduction

Cell division = splitting the cell in two new cells

Useful bacteria

Most bacteria are useful:

• Help digest food in our intestines
• Kill harmful bacteria on our skin
• Feed on dead organisms
• Can be used in making food: Yoghurt, Sauerkraut

Harmful bacteria

• Cause diseases
• Spoil food

Antibiotics (like penicillin) kill bacteria
