• Eukaryatic
• Unicellular
• Protozoa and Algea

• Heterotrophic
• No cell walls
• most by binary fission
•  classified based on locomotion

• Move by Pseudopods (amoeboid mov't)
• Binary Fission
• Phagocytosis
• simple diffusion
• form cyst that is a body covering that can resist stressful conditions
• entamoeba histolytica causes amoebi dysentery

phylum Ciliophora (paramecium)

• Move by cillia
• binary fission- asexual
• conjugation- sexual micro and macro nucleus
• exchanges micronucleus
•  most free living
• simple diffusion
• surronded by pellicle
• form food vacuoles, food taken at the oral groove

Phylum Mastigophora (zoomastigina)

Ex: Trypanosoma

• Move by Flagella
• Binary Fission
• simple diffusion
• Trypanosoma causes africal sleeping sickness invades nervous system, it's vector is the tsetsefly
• Euglena is another example

Phylum Sporozoa (Apicomplexa)

Ex:Taxoplasma gondii, Plasmodium

• intracellular parasites
• alternate between sexual and asexual
• simple diffusion
• sessile
• ex Taxoplasma gondii:- sexual cat, asexual human; toxoplasmosis causes birth defects
• Plasmodium- malaria; vector, female Anopheles mosquito 

• Autotrophic
• sexual and asexual
• Photosynthesis with chloroplast and chlorophyll
• classification based on pigment 

• pigment  fucoxanthin masks chlorophyll
• free living
• includes diatoms which have a silcon shell

Phaeophyta- brown algea

Olive to dark brown

includes giant kelp

• pigment phycobilians
• phytoplankton floating communities of photautrophs

Green Algea

ancestors of green Plants

unicellular and colonial

Miscellaneous

A: Actinopods- ray feet

• mostly plankton

B: Dinoflagellates

• have 2 flagella
• red tide- toxic bloom

C: Slime Molds

• Free living amoeba like oraganisms
