|
fungi cell walls
|
consist of chitin- polymer that consists of N-containg sugar
|
|
|
2 types of fungi
|
molds and yeast
|
|
|
mold
|
Hyphae: long, branched filaments. Their elongation allows the fungus to absorb nutrients
mycelium: mass of hyphae septa: walls that divide hyphae |
|
|
yeasts
|
unicellular; round shape.
|
|
|
Fungi reproduction
|
Spores are produced in fruiting bodies located on the aerial hyphae.
|
|
|
Sexual reproduction in fungi
|
the hyphae of 2 fungi come together and their cytoplasm and nuclei fuse. This creates a zygote.
If they are different kinds of fungi, the hyphae fuse but the nuclei remain seperate. This is known as "dikaryotic" (n+n). |
|
|
Asexual reproduction
|
when a spore lands on something it germinates and grows. A hypha emerges and branches. mycelium infiltrates the fruit and fungus absorbs.
|
|
|
Lichen
|
a symbiotic association between a phototroph (algae or cyanobacteria) and a fungus.
|
|
|
Mycorrhizae
|
mutualistic relationship b/t fungi and roots of the plants
fungi provides water and nutrient minerals roots provide sugars and amino acids |
