Protists & Fungi Flashcards
Protists
Taxonomic group that consits of eukaryotic organisms
Characterisitics of protists
Unicellular
Autotrophs or Heterotrophs
Symbiotic relationships or free living
Reproduce asexually
Found in moist environments
Categories of Protists
Plant like
Fungus like
Animal like
Plant like protists
Photosynthetic autotrophs found in water
Contain chloroplasts
Use photosynthesis as food source
Examples of plant like protists
Red algae
Euglenoids
Fungus like protists
Slime molds or water molds
Similiar to kingdom fungi, fungi like protists reproduce via spores
No chitin
Heterotrophic: decomposers and saprobes that feed on non living organic matter
Animal like protists (protozoa)
Based on motility; cilia or flagella
Capable of movement
single celled
heterotrophic
engulf and feed on algae, fungi, and bacteria via phagocytosis
Examples of animal like protists
Amoebas
Ciliates
Amoeba
Animal like protists (protozoa)
Pseudopodia for movement
Pseudopodia
arm like projections that emerge towards direction of movement
mainly cytoplasm
Fungi structure
Uni or multicelluar
cell walls contain chitin
Sporangium
Multicellular organ where meiosis occurs, and haploid cells (spores) are formed
Rhizoids
Small branching hyphae that anchors structures to the ground
Fungi types
Non filamentous fungi
Filamentous fungi
Non filamentous fungi
Unicellular (includes yeast)
Asexual reproduction by budding via mitosis
Filamentous fungi
Multicellular (molds/ mushrooms)
Sexual or asexual repdocution
mushroom grow outward from mycelium
Mycelium
Network of fungi filaments (hyphae) that connect fungi together
Mycelium functions
Secrete enzymes that break down organic matter
Releases nutrients for absorption by hyphae
Allows fungi to be effective decomposers
Hyphae
Filamentous branches produced by multicellular fungi as they grow
Septate hyphae
Have septa (cells walls that seperate hyphae)
Coenocytic hyphae
No division of hyphae
Multinucleated
Reproduction
Can reproduce sexually, asexually, or both
Haploid for most of their life cycle
