fungi cell walls
consist of chitin- polymer that consists of N-containg sugar
2 types of fungi
molds and yeast
Hyphae: long, branched filaments. Their elongation allows the fungus to absorb nutrients
mycelium: mass of hyphae
septa: walls that divide hyphae
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.
a symbiotic association between a phototroph (algae or cyanobacteria) and a fungus.
mutualistic relationship b/t fungi and roots of the plants

fungi provides water and nutrient minerals

roots provide sugars and amino acids
