Prokaryotic cells

• Structure of prokaryotic cells:

  Cell membrane, slime capsule, plasmids, genetic material, cytoplasm, cell wall, flagella
• Prokaryotes are single-celled organisms whose cells lack a nucleus and other organelles.
• Bacteria are prokaryotic cells.
• Plasmids: Small rings of DNA
• Genetic material: A single DNA loop not enclosed in a nucleus and found free in the cytoplasm
• Slime capsule: Around the outside of the cell wall to protect the cell, help cells to cling together and prevents them from drying out.
• Flagella: A long protein strand allowing bacteria to move around.
• Prokaryotic cells are extremely small compared to eukaryotic cells.
