BIOL 1108 Lecture Notes - Lecture 20: Basidiomycota, Dikaryon, Mycelium
Document Summary
Core concepts: fungi are heterotrophic eukaryotes that feed by absorption, fungi reproduce both sexually and asexually, and disperse by spores, other than animals, fungi are the most diverse group of eukaryotic organisms. Core concept 1: fungi are heterotrophic eukaryotes that feed by absorption: fungi are eukaryotic organisms, they differ from plants by: Storing e in glycogen rather than starch. Their cell wall is composed of chitin (n-glucose: they differ from animals: Inability to capture prey or solid food particles by phagocytosis: most fungi are multicellular organisms composed of long filaments (hyphae) that are only one cell thick, plants are autotrophs (self-feeding, animals are ingestive heterotrophs, fungi are absorptive heterotrophs. Saprophytes = decomposers = feeding off dead organisms. This style in particular is called a fairy ring". Lots of shapes and colors: mating types vary in fungi, no sexes per se, the mating type of an individual is determined by a mating-type gene.
