lecture 8 Flashcards
Protists, plants, and fungi are examples of ….
eukaryotes
eukaryotes
have a nucleus
prokaryotes
don’t have a nucleus
what does plasmodium cause
causes malaria (mosquito bites)
what happens when you have malaria
infects liver+blood cells
algal bloom
dinoflagellates
why is agal bloom a problem
toxins in shellfish
food chains
show energy gained from consumption
what is a main category of primary producer protists
photosynthetic protists
what study is used to study protist cell structures?
microscopy
what is a motility structure studied?
flagella
what is second technique used to study protists and terms to know
phylogenetic trees
-synapomorphy
-monophyletic group
-paraphyletic group
what technique is used to discover new lineages of protists
direct sequencing
endosymbiosis
eukaryotes emerged when prokaryote ingested or infected another prokaryote
what are 3 methods protists obtain food
ingestive feeding (heterotroph)
absorptive feeding (heterotroph)
photosynthesis (autotroph)
what are three main structures for motility
-flagella
-cilia
-psuedopodia (fake feet)
what are 2 main types of plants and where do you find them?
green algae (aquatic)
land plants (terrestrial)
what do ecosystems get from green algae and plants?
food/nutrients
help soil
help w/ water
what do humans get from green algae and plants?
oxygen
herbs/medicine
foods/nutrients
seed plants
embryo of plant with some nutrient tissue around it
gymnosperms
naked seed
angiosperms
fruit around seed
what 2 structures did plants develop to prevent water loss?
cuticle and stomato
what do plants produce to protect from UV
flavonoids
