Microbial groups
Eucaryotes
fungus:primary terrestrial,few freshwater and marine
slime/water molds:resemble fungi in appearance and style
algae:simple aquatic plants,lack of vascular conducting system and simple reproductive system
protozoa:motile eucaryotic unicellular protist
nutrition
holozoic nutrition
saprozoic nutrition
Reproduction
asexual:binary fission
sexual:conjugation
ecological role
in marine food chain
interaction with higher organism
distribution
planktonic
benthic
neustonic
Nutrition:photoautotrophic or chemoheterotrophic
Reproduction:sexual or asexual reproduction

obligate intracellular parasites
cannot replicate outside the cells
replication steps:
a)attachment/absorbtion
b)penetration
c)replication
d)assembly
e)release
ecological functions
