Document Summary
Fungi and plants are two distinct, multicellular eukaryotic clades. Fungi are more closely related to animals than they are to plants. Fungi are heterotrophs with complex life cycles: sexual/asexual reproduction. Fungi have ancient and important ecological associations with plants. Plants are photoautotrophs with complex life cycles: alternation of generations (n, 2n) Multicellular organisms occur in several clades: not the same as colonial, ex. slime molds (cellular and a cellular) Unikonta is divided into two main groups: amoebozoa. Molecular clock: 1 gy for animal-fungi split. Oldest fossil fungi: 0. 46 gy = 460 my. Even though fungi are often taught with plants, they have much more in common with animals. Fungi are (generally) multicellular heterotrophs: absorb nutrients without ingestion (unlike animals( Many little filaments intertwined together to form a larger 3-d structure called a mycelia. Hyphae may be divided by septa or not (coenocytic) Coenocyte- one giant cell with many nuclei. Fungi have complex life cycles: reproduce by producing spores, sexual reproduction:
