inside bacteria

• bacteria are difficult to see with a light microscope because they are very small and colourless. stains are often used to make them show up
• the extra magnification and resolution of an electron microscope allow scientists to see bacteria in more detail
• flagellum - spins around so the bacterium can move
• chromosomal dna - controls the cells activities
• plasmid - controls a few of the cells activities
• prokaryotic - does not have a nucleus
• the cytoplasm contains one large loop of chromosomal dna
• prokaryotic cells do not have a nucleus, mitochondria or chloroplasts.
• flagellum is not covered in a membrane and not all bacteria have them but some have many
• slime coat for protection - not all bacteria have
• flexible cell wall for support - not made of cellulose
• cytoplasm contains ribosomes which are smaller than eukaryotic ribosomes
• bacteria have 


  flagellum, plasmids, chromosomal dna, slime coat, flexible cell wall, cell membrane, cytoplasm
• state two sub-cellular part that bacterial cells may have but animal cells never have: flagellum, plasmids
