Nature of bacteria and fungi

Nature of Bacteria and Fungi

Higher Level only


Learning objectives
Learning Objectives

  • Discuss the prokaryotic nature of bacteria

  • Discuss the eukaryotic nature of fungi


Prokaryotic and eukaryotic
Prokaryotic and Eukaryotic

  • Living things can be divided into two categories with regard to the structure and complexity of their cells:

    • Prokaryotes

    • Eukaryotes


Prokaryotic and eukaryotic1

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


Prokaryotic and eukaryotic2
Prokaryotic and Eukaryotic organelles e.g. bacterial cells


Prokaryotic bacteria
Prokaryotic - Bacteria organelles e.g. bacterial cells

  • Bacteria are prokaryotic cells

  • Their kingdom Monera is also referred to as prokaryotae

  • They are extremely small (0.5 – 10 μm)


Prokaryotic bacteria1
Prokaryotic - Bacteria organelles e.g. bacterial cells

  • 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


Eukaryotic fungi plants animals protists
Eukaryotic – Fungi, plants, animals, protists organelles e.g. bacterial cells

  • The cells of all other kingdoms are eukaryotic

  • More advanced

    • they have a true nucleus and membrane enclosed organelles

  • evolved from prokaryotic cells


Learning check
Learning Check organelles e.g. bacterial cells

  • What two categories can cells be placed in?

  • In what way does a bacterial cell differ from a fungal cell?


Syllabus
