E.g. RNA is HIV and DNA is flu 5 of 7 PROCTOCTISTA Single celled- all life process happen Microscopic and have animal and plant characteristics Pathogenic (E.g. Plasmodium which causes malaria when transmitted by mosquitoes) 6 of 7 FUNGI Heterotrophic Chitin cell wall Single celled e.g. yeast / made out of hypae interwcave to make mycellum e.g. moulds Glycogen is carbohydrate store Pathogenic - causes diseases (e.g. atheltes food, the fungus causes the irish potatoe famine 7 of 7
