Microprotozoan
* All protozoans are heterotrophs and live as predators or parasites
  - get food from their environments
* Many protozoans are obligate parasites with complex life cycles involving several organisms
  - have a wide host range
  - move about by means of appendages known as cilia or flagella
  - reproduce both asexually and sexually during their lifetime
* Most protozoan can move
  - protozoans affect animals
* Most protozoans are aquatic chemoorganotrophs
  - heterotrophs oxidizing inorganic compounds
  - heterotrophs, whereas others are autotrophs
* Most protozoans cause diseases
  - spot diseases
  - white spot diseases
  - contain nitrogen
  - feed on food particles
* Most protozoans feed on large food particles
* Most protozoans find in clear water
* Most protozoans inhabit human intestines
* Most protozoans invade mantle tissue
  - live in environments
* Protozoan microorganism.
* Protozoans are a diverse group of organisms
  - group of eukaryotic single-celled organisms
  - all single-celled and heterotrophic
  - among the most versatile of all organisms on earth
  - autotrophic, and algae are heterotrophic
  - complete, single celled organisms
  - eukaryotic cells
  - generally lightly-colored, flexible, motile, heterotrophic cells
  - heterotrophic protists
  - microscopic one-celled animals, most of which are harmless
  - phylums
* Protozoans are single celled organisms that sometimes have complex life cycles
  - with no cell walls or chlorophyll
  - single-cell, heterotrophic eukaryotes
  - single-celled organisms that have nuclei and act somewhat like animals
  - somatic cells
  - the nnost aninnal-like of the protists
* Protozoans are unicellular animals that are motile
  - organisms that have a true nucleus
* Protozoans are unicellular, and can be classified on how they move and live
  - heterotrophic organisms
* Protozoans can exist almost everywhere including water, soil, and inside animals or plants
  - produce haploid gametes that fuse through syngamy
  - use flagella, cilia, or pseudopods to move
  - digest food within food vacuoles
  - other organisms but also use chlorophyll, so some are a major relative of plants
  - form cysts when it becomes too cold or too dry
  - furnish a large amount of food to the higher animals
* Protozoans have a variety of reproductive mechanisms
  - unique organelles and sometimes lack organelles found in other cells
  - an impact on people in several ways
  - internal shells that they produce
  - several special features
* Protozoans includes cell membranes
  - corpi
  - cytoplasm
  - lips
  - mouths
  - plasma membranes
  - sections
* Protozoans inhabit a wide variety of habitats, both aquatic and terrestrial
* Protozoans live in environments that vary from soil to the bodies of other organisms
  - moist environments
  - move toward moderate light and temperature and food
  - pose a hazard primarily in areas lacking sanitary conditions
* Protozoans reproduce by budding, splitting, or forming spores
  - splitting into two identical daughter cells like bacteria or algae
  - sexually and asexually
  - require a moist environment
  - show mainly two modes of life, free living and parasitic
  - use either dissolved food molecules or small organisms for food
  - usually live near sources of water
* Some protozoans also reproduce by budding.
* Some protozoans are harmful to man as they can cause serious diseases
  - so small that they parasitise the cells of the host they inhabit
  - transmitted to humans
  - break down wood
* Some protozoans cause diarrhea
  - giardiasises
  - health problems
  - infection
  - lung infection
  - malaria
* Some protozoans cause serious health problems
  - sickness
  - sleep sickness
  - tract infection
  - find in ponds
* Some protozoans have chemicals
  - contractile vacuoles
* Some protozoans have enormous potential
  - reproductive potential
  - little or no locomotory activity, such as the apicomplexans
  - long flagella
  - no means of movement
  - phases
  - types
  - help cellulose
* Some protozoans infect cats
  - children
  - dogs
* Some protozoans live in intestines
  - stomachs
  - move by means of one or more flagella
* Some protozoans produce enzymes
  - infective spores
  - reproduce sexually as well
