Lab 3 Flashcards
new defining characteristic that all fungi share is:
synapomorphy
prokaryotes
have no nuclear membrane
eukaryotes
have cells with nuclei bounded by nuclear membrane
archaea
live in very strange and hostile habitats, suhhc as very salty, hot, or acidic environments
eubacteria
all have peptidoglycan cell walls
cocci
spherical
bacilli
rod-shaped
spirilla
helical
cyanobacteria
major group of these photosynthetic bacteria
nitrogen fixers
convert molecular nitrogen from the atmosphere into forms of nitrogen that are usable
alveolata
all contain cavities called alveoli
ciliates (paramecia)
distinguished by the structures that enable them to move: cilia
dinoflagellates (peridinium)
photosynthetic autotrophs (w chlorophylls a & c)
stramenopiles
have fine hairs on their flagella
brown algae
seaweeds that are photosynthetic autotrophs, multicellular
diatoms
algae that are photosynthetic. encased in a silica shell
rhizaria
have slender pseudopodia. also has holes in its shell to catch food.
excavata
modified mitochondria
euglenozoa
use flagella to move. unique structure called a kinetoplast, which contains DNA and proteins that help w mitochondrial function
Diplomonads
simple protists that have two nuclei
amoebozoans
have blunt pseudopodia
amoeba
locomotion is via pseudopodia
what is a defining feature of fungi
chitin
zygomycota
have the hyphae (filaments that make up the body of the fungus) of adjoining individuals extend branches that make contact, coalesce, and form gametes
ascomycota
form reproductive structures called asci. each ascus usually has eight of these spores
Basidiomycota
members of this group all reproduce sexually via basidia
