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
what is a fruit and purpose
derived from ovary and encloses seed/seeds
purpose: help disperse seeds
cotelydon
nutrient leaf
monocot
1 cotelydon, multiple of 3 petals
dicot
2 cotelydon, multiples of 4 or 5 petals
fungi
yeast+mold
mutalists
benefits both organisms
parasites
one benefits one harmed
how does incidence of fungal infections compare to bacteria and viruses
fewer incidence
mycorrhizal
roots of plants
increase size of plants/extra nutrients
saprophytes
on dead plant matter
what are the two possible growth forms of fungi
yeast and mycelium
what are fungal filaments called
hyphae
budding
asexual reproduction
