Term
Protists
Definition
algae and protozoans, most unicellular
Term
Clade
Definition
group of species that are all descended from one ancestral species representing one phylogenetic group
Term
autotrophic
Definition
photosynthetic; gets energy through light, and converts sun's energy to organic compound
Term
heterotrophic
Definition
depending on other organisms for energy and food
Term
primary production
Definition
amount of energy stored by autotrophs
Term
Algae
Definition
autotrophic protists
Term
Protozoa
Definition
heterotrophic protists
Term
Where do protists live
Definition
most are aquatic(plankton) but many others live almost about anywhere
Term
Clade Euglenozoans, give an example
Definition
mixotrophic(photosynthetic and can ingest,
group based on the structure of their flagella, example: Euglena
Term
phagocytosis
Definition
eating large organisms by pinching inward of the plasma membrane
Term
Euglena
Definition
flagella, eye spot, chloroplasts, euglenoid motion
Term
Flagellum
Definition
at the end of the eyespot, looks like skinny tail
Term
Clade Alveolates, common characteristics, give examples
Definition
single-celled organisms, mixotrophic
Common characteristic: sac-like structures of alveoli just under cell membrane.
Examples: Paramecium caudatum
Term
ciliates
Definition
bristles on the edge of the structures that helps move
Term
Paramecium caudatum
Definition
organism that belongs to clade alveolata and is heterotrophic. has cilia, oral groove, food vacuoles, contractile vacuole, and trichocysts
Term
oral grooves
Definition
perpendicular opening like a paper cut that runs through the gullet
Term
food vacuoles
Definition
at the end of gullet
Term
contractile vacuoles
Definition
helps water balance, at the end of each cell which looks like arms, and looks like tube
Term
trichocysts
Definition
discharged when irritated by something, long thin threads
Term
Clade Amoebozoans, example
Definition
lobe-shaped pseudopodia,
Example: slime molds
Term
slime molds
Definition
part of clade amoebozoa, heterotrophic,
Term
plasmodial slime molds, give example
Definition
multinucleated mass of protoplasm
example: physarum polycephalum
Term
Physarum polycephalum
Definition
slime mold, cytoplasmic, fruiting bodies(reproduction), amoeboid cells
Term
Zygote Fungi, give examples
Definition
made of filaments called hyphae which are organized into mycelium (body of fungus)
Example: Rhizopus stolonifer and Pilobolus crystallinus
Term
Chitin
Definition
cell wall of fungi
Term
Rhizopus Stolonifer
Definition
produces sexually and asexually, haploid, develop sporangia,
Term
sporangia
Definition
asexually,round structures on tips of hyphae, haploid spores are developed inside.
Term
zygosporangia
Definition
sexually, haploid nuclei fuse producing diploid nuclei.
Term
Pilobolus crystallinus
Definition
shotgun, coprophilous fungus, grows on dong, phototrophic
Term
Ascomycota, give examples
Definition
sac fungi, ascopore producing fungi, edible fungi, morels, truffles
example: sordaria fimicola
Term
Basidiomycota
Definition
club fungi, mushrooms, plant dieases, wheat rust, corn smut
Term
Deuteromycota
Definition
imperfect fungi, develop human diseases, some beneficial species like penicillium
Term
Linchens
Definition
symbiotic between fungi and alge, can survive harsh enviroments
Term
thallus
Definition
lichen body
Term
foliose
Definition
leafy thallus
Term
crustose
Definition
crustlike thallus
Term
fruticose
Definition
cylindrical thallus
