Document Summary
Fungi have traditionally been grouped with plants, but they are actually closer related to animals. Found on land and in the sea/fresh water. They digest their food externally hydrolytic enzymes. Fungi will eat almost anything (molds do this) All fungi have cell walls, mainly made of polysaccharide chitin. Reproduce by releasing spores (mainly asexual, sometimes sexual) Sporangia : hollow structures in which spores are produced. Conidiogenous cells : specialized hyphal cells which give rise to spores called conidia. Plasmogamy is the fusion of the gametangial protoplasts. Karyogamy is the fusion of the nuclei may be delayed. Results in the formation of a diploid zygote. Meiosis immediately follows to restore the haploid condition. Fungi spend most of their lifecycle in the haploid phase. Unicellular (but some have rhizoids as an anchor) Produce zygosporangium; a thick walled sexual resting structure. Asexual spores produced in sporangia grow directly from haploid mycelium. Meiosis occurs haploid sporangium emerges from zygosporangium to produce.
