Eumycota

A clade called “true fungi”

Chitin

Chitin

A polysaccharide made from monomers of N-acetylglucosamine

Extracellular Digestion

How fungi obtain nutrients; they secrete enzymes into the environment

sterols

polycyclic lipid molecules in fungi plasma membranes that maintain membrane fluidity and integrity despite temp variation; may play roles in cell cycle regulation, stress responses, and other cellular function

ergosterol

most abundant sterol in fungal membraens

mycosis

a disease caused by any fungus

malassezia globosa

fungus in the human skin that metabolizes sebum

mycorrhizae

a type of symbiotic association with plants in the phosphate cycle

Lichen

protists

a diverse, paraphyletic group of non-fungal, non-animal, and non-plant microbial eukaryotes

protozoa

eukaryotic algae

algae

photoautotrophic organisms that are not plants (cyanobacteria)

eukaryotic algae

what category are these : diatoms, dinoflagellates, coccolithophores, red algae, green algae, yellow-green algae, green algae, brown algae, glaucophytes

both

are eukaryotic algae unicellular or multicellular

eukaryotic algae

can contain different pigments and plastids and do not have cuticles that prevent water loss

protozoa

what category are these: apicomplexans, ciliates, diplomonads, euglenids, forams, jakobids, kinetoplastids, oomycetes, parabasalids, radiolarians

protists and bacteria

what do protozoa consume

trophozoite

a feeding form of protozoa

cyst

a dormant form of protozoa; marked by a thick wall that confers protection against adverse environmental conditions
