Prokaryotes
Acellular Organisms
What Is An Example of Prokaryotes ?
Bacteria are all examples of prokaryotes.
What are some eukaryotic microorganisms ? some fungi, some algae, yeasts

Attack parasitic worms and involved in allergic and asthmatic reactions
What’s the job of T Lymphocytes?
Attack and destroy viral infected body cells and tumour cells
What’s the job of Basophils?
Stimulate vasodilation and attract other WBC to areas of infection and inflammation
What are B Lymphocytes ?
Produce antibodies which identify and mark foreign antigens for destruction
