1.3 Describe The Common Features Shown by Prokaryotic Organisms such as Bacteria.

Bacteria:

• Microscopic single-celled organisms;
• They have:
• a cell wall
• cell membrane
• cytoplasm
• plasmids
• They lack a nucleus but contain a circular chromosome of DNA
• Some bacteria can carry out photosynthesis but most feed off other living or dead organisms.
• e.g.
• Lactobacillus Bulgaricus - a rod-shaped bacterium used in the production of yoghurt from milk.
• Pneumococcus - a spherical bacterium that acts as the pathogen causing pneumonia.
