Review Sheet #7: Fungi, Algae, and Protists Flashcards
Mycellium
A matt of hyphae
Actinomycetes
- Gram +
- High G+C content
- Bacteria that act like golgi
Exospores
Produced by asexual sporulation
Formed outside cell wall
Endospores
Formed inside cell wall
By sexual sporulation (?)
Classes in Eumycota (6 total)
- Basidiomycota
- Zygomycota
- Ascomycota
- Chitrids
- Glomeromycota
- Microspora
Basidiomycota
- Typical mushroom
- Smuts, rusts, and plant pathogens
- Basidiospores in gills
Zygomycota
Bread mold
Spores have thick, black coats
Ascomycota
- Spores surrounded by ascus (sac)
- Yellow mold
- Morell, yeast, pombe
Chytrids
- Live underwater
- Parasites
- Flagella
Glomeromycota
- Symbiotic with plants
- Mycorhizae
Microspora
- Used to be considered protists
- Pathogens
- Spring loaded polar filament
Streptomyces makes…
Antibiotics
4 important actinomycetes
- Mycobacterium
- Soil Bacteria
- Streptomyces
- Bifidobacterium
Mycobacterium
Acid fast (mycolic acid)
Soil Bacteria
Gives dirt its smell
Bifidobacterium
Probiotic
Mycology
Study of Fungi
Thallus
- Form/Body of organism
- Not a phallus
Dikaryotic
- Stage of sexual reproduction
- Nuclei share cytoplasm, no fusion
5 Characteristics of Eumycota
- Eukaryote
- Saprophyte
- Sexual and Asexual Reproduction
- No photosynthesis
- Chitin in cell wall
Saprophyte
Secretes enzymes onto dead organic material, then absorbs soluble product
Coencytic Hyphae
Nuclei sharing 1 cytoplasm
Septate Hyphae
Hyphae have divisions between cells
Protist Classification (3)
- Sarcomastigophora
- Apicomplexa
- Euglenoids
4 types of sexual sporulation
- Arthrospores
- Sporangiospores
- Conidiospores
- Blastospores
Arthrospores
Hyphae fragments —> Spores
Sporangiospores
Sac of spores surrounded by membrane
Conidiospores
Naked chains of spores
Blastospores
Made by budding
Rhizoidal Hyphae
Hyphae growing down like roots
Aerial Hyphae
Hyphae pointing up
Fungal YM Shift
Switching modes of growth Yeast/Mycelium
2 types of growth in fungal YM shift
- Yeast
2. Mycelium
Sexual Sporulation in 3 types of Eumycota
- Basidiomycota
- Zygomycota
- Ascomycota
Cell Division in S. Cervisiae
Budding
Cell Division in S Pombe
Fission
Mycorhizae
Fungi-roots into the body of plant. Grows on/into plant
Plasmodium
Structure of mold, no cell wall. Cytoplasm
Fruiting body
Part of fungus that contains spores
“Slug”
Slime mold on the move when nutrients scare
Dictyostelium
Cellular slime molds
Amoeba
Slug
Algae characteristics
- Eukaryote
- Oxygenic photosynthesis with chlorophyll
- Lacks vasculature system
Phycology
Study of Algae
Pyrenoid
Large Structure for Starch Storage inside chloroplast.
Eyespot
Photosensitive
Fragmentation
Each cell of a multicell organism can become a unique organism
Green Algae
- Chlamydomonas
2. Volvox
Chlamydoonas
1 cell, 2 flagella
Big eyespot
Volvox
1,000 chlamy-like cells in a ball
Golden-Brown/ Yellow-Green algae
Diatoms, Frustules
Frustules
2-part protective coat
Brown Algae
- Kelp and other seaweed
- Each cell does own photosynthesis
Red Algae
- Deeper in Ocean
- Makes Agar
- Decreased light = lower wavelength = red
2 specific green algae
- Chalmydomonas
2. Volvox
2 algae important to plankton
- Diatoms
2. Dinoflaggelates
