Green algae were switched to Kingdom Viridiplantae
Evidence that the chloroplasts of some brown algae evolved differently than in green algae
Chlamydomonas
unicellular, motile, green algae
The tinny green dots that where moving around on the open slide.
Chlorophyte
unicellular motile
Kingdom Fungi
Members play vital roles in ecosystems (decomposition, nutrient cycling, symbiosis, etc.)
Ergot of Rye (Ascomycota)
What the witches had.
Cordyceps-That infects bugs.
Mycelium
most of the growth of the mushroom that is under the mushroom which is part of the mushroom.
Where are the spore producing structures
in the bottom brown part of the mushroom
Where is the hyphae located on the fungi
towards the bottom connecting to the mycelium
What is the reproductive part of the mushroom
The part of the fungi that is sitting above ground.
fungi characteristics
Non-photosynthetic eukaryotes with chitinous cell walls
Mostly multicellular, some unicellular (yeasts)
Cells can be septate (cell walls divide individual cells) or aspetate no dividing wall between cells)
saprophytic
obtain nutrients from dead/decaying organic matter
symbiotic=parasitic or mutualism
Mycorrhizae
fungus infects plant root cells and gets carbohydrates, plant gets nutrients/protection from other microorganisms
Lichen
photobiont lives within fungus
Sexual reproduction of fungi
Sexual = Spores (specialized cells that germinate into new vegetative growth)
Produced by meiosis
Produced by meiosis- the three steps?
Basidiospores, ascospores, zygospores (meiospores)
Reproduction asexual
- Spores - (mitospores) 2. Budding – offspring grow attached to adult until mature then break off (yeasts) 3. Fragmentation – piece of fungus breaks off, forming new individual
Phylum Zygomycota
There is no dikaryotyic stage in the life cycle, no two nuclei in the same cell.
There is still division
Algea distinguishing characteristics
Which pigments they have,
cell wall components
storage compounds
Phylum Ascomycota –
sac fungi
with 8 ascospores (meiospores)
Asci line the surface of the ascocarp (fruiting body)
Sexual Reproduction for Phylum Ascomycota occurs on
occurs on ascocarp, produces 1n ascospores
The outside little hairs.
Phylum Basidiomycota common name
Club fungi
Named for formation of basidium/basidia…
with 4 basidiospores (meiospores)
Where do the Basidia form on the fungi (mushroom)?
form on the gills or in pores of the basidiocarp (fruiting body)
Basidiocarp
pileus, stalk, gills
