- A bacterium has plasmids.
- Plasmids and small, circular pieces of DNA.
- The plasmids do not need chromosomes in order to split.
- They also have chromosomal DNA, which carries the genetic information.
- They differ from plant and animal cells because they don't have a nucleus.
- They also don't have mitochondria.
- It has a cell wall surrounding the cell membrane.
- The cell wall is similar to a plant cell's, but is more flexible.
- Some bacteria have a flagellum.
- A flagellum is like a tail and helps the bacteria move.
- Some bacteria have more than one flagellum, called flagella.
- Some bacteria have none.
- Bacteria live in the intestines and help with digestion.
- They help with the production of foods such as cheese and yoghurt.
- They help with the decomposition and recycling of dead plants and animals.
- They help with the production of antibiotics.
- Photosynthetic bacteria can produce oxygen.

- It has a cell wall.
- It has a vacuole.
- The cell wall is made from chitin.
- Chitin is the material arthropods make their exoskeletons with.
- Yeast reproduces asexually.
- This process is known as budding in a yeast cell.
