Presentation Transcript

  1. Nature of Bacteria and Fungi Higher Level only

  2. Learning Objectives • Discuss the prokaryotic nature of bacteria • Discuss the eukaryotic nature of fungi

  3. Prokaryotic and Eukaryotic • Living things can be divided into two categories with regard to the structure and complexity of their cells: • Prokaryotes • Eukaryotes

  4. Prokaryotic cells do not have a nucleus or membrane enclosed organelles e.g. bacterial cells Eukaryotic cells have a nucleus and membrane enclosed organelles e.g. plant, animal, protist and fungal cells Prokaryotic and Eukaryotic

  5. Prokaryotic and Eukaryotic

  6. Prokaryotic - Bacteria • Bacteria are prokaryotic cells • Their kingdom Monera is also referred to as prokaryotae • They are extremely small (0.5 – 10 μm)

  7. Prokaryotic - Bacteria • As they do not have a true nucleus, bacterial DNA is found as a circular loop floating freely in the cytoplasm • They do not have membrane enclosed organelles like mitochondria and chloroplasts

  8. Eukaryotic – Fungi, plants, animals, protists • The cells of all other kingdoms are eukaryotic • More advanced • they have a true nucleus and membrane enclosed organelles • evolved from prokaryotic cells

  9. Learning Check • What two categories can cells be placed in? • In what way does a bacterial cell differ from a fungal cell?

  10. Syllabus

  11. Depth of treatment • Prokaryotic nature of bacteria • Eukaryotic nature of fungi
