Fungus anatomy Most of a fungal organism exists below ground Hyphae – individual mycelium
Supper time! • absorb nutrients from living or dead organic matter they grow on. • release enzymes to break down nutrients into simpler forms that they can absorb through their cell walls. http://vimeo.com/28483128
Fungi Asexual Reproduction: budding • Mostly occurs in yeast • a new organism grows out of another • One single yeast cell can produce up to 24 other cells (Fungal Growth and Reproduction 2012) http://www.youtube.com/watch?v=BTHYaf-EuYs&feature=related
Fungal Sexual Reproduction: Spores • cells from 2 different hyphae fuse together • Form a spore stalk. • Spores are released http://www.youtube.com/watch?v=KbNRlVoxri4
