Kingdom includes all eukaryotes except green plants, animals and fungi
Not monophyleyic
Most diverse kingdom
Reproduce asexually most of time
Protists
Major difference between prokaryotes and eukaryotes
Cytoskeleton
Compartmentalization
Used for propulsion and feeding
Cilia
Protective outer forgetting in dormant cell
Cyst
Movement and feeding
Pseudopodia
Ingest particle food
Phagotropic
Ingest soluble food
Osmotrophic
Pritistan mechanisms
-slimy gate coverings Toxins Sharp projectiles Spines Bioluminescence
Diplomonads characteristics
Unicellular Move with flagella 2 nuclei Giardia (causes diarrhea) No mitochondria but have it in DNA
Protistan nutrition

Heterotrophs
Mixotrophs
Earlier eukaryotes to have mitochondria
No sexual reproduction
Flexible pellucle
Heteritrophic in dark
Euglenozoa
Photosynthetic
Unicellular
Has flagella
Dinoflagellates
2nd major group in euglenozoa
Single mitochondrian
Kineplastids

Tsetse fly
Disease caused by contact w urine/blood of infected animal. Heart increases in size
Chagas’ disease
Severe lesions caused by sand fly
Leishmaniasis
Major cause of red tide (blooms that kill fish, birds and marine mammals.
Dinoflagellates
Spore forming animal parasites
Arrangement of organelles that enables cell to invade host
Apicomolexans
Caused by plasmodium
Symptoms include chills & fever in late afternoon
Malaria
Unique double shells made of silica
Photosynthetic
Unicellular
Diatoms
Tough but flexible outer covering
Pellicile
Cilates will reproduce asexually without
Micronucleus
Essential for ciliates function
Macronucleus
2 types of ciliates nuclei
Micrinucleus
Macrinucleus
Filter bacterial food from water
Similar to sponges and humans
Propulsion by single posterior flagellum
Choanoflagellates
Move by pseudopodia extension
Amoebae
Resemble tiny snails
Shells called tests
Tests help make up limestone deposits
