bio protists

• -eukaryotic
• -unicellular
• -solitary or colonial
• -1.5 billion years old

difficult to classify

first protists came from symbiosis (both species benefit)

-have similar organelles to prokaryotes

organisms that live in a host organism

• Ciliophora
• Zoomastigina
• Sporozoa
• Sarcodina

• common names: ciliates
• cilia for movement
• found in fresh + salt water
• free living

• -cilia force water into gullet
• -food then forced into vacuoles
• -vacuoles moved moved to cytoplasm and fuse w/ lysosomes for digestion
• -waste out anal pore

• Binary Fission
• conjugation

genetic info exchanged...genetic diversity

• Taxoplasmosis - sporozoa
• Giardia lamblia - zoomastigina
• African sleeping sickness - zoomastigina
• Malaria(plasmodium) - sporozoa

cats

weakened immune system

contamintaed water or food

• tsetse fly
• -effects immune system
• -lose control of muscles
• -uncontrollable sleepiness

• euglenophyta
• pyrophyta
• chrysophyta
• ascarasiomycota
• myxomycota

• common name: Flagellates
• role: symbionts/parasite
• features: flagella for movement

reproduction: sexual/asexual

• common name: sporozoans
• -parasitic
• -spores for reproduction
• -non motile

• role: symbionts
• feature: pseudopods for movement +feeding
• repro: binary fission

• "euglenas"
• -freshwater
• -producer
• -flagella
• -choloroplasts

asexual

• "dinoflagellates"
• -photosynthetic
• -free living
• -luminescent
• - surrounded by thick plates
• asexual

"chrysophytes"

• free living
• photosynthetic
• cell walls, glasslike rich in silicon

"cellular slime molds"

• -decomposer
• produce spores by mitosis
• acts multicellular

• "acellular slime molds"
• free living

• produce spore by meiosis
• produce diploid ameboid cells, fuse, repeat cycle.
