BY 108 Chapter Notes - Chapter 27: Homokaryotic, Spindle Apparatus, Heterokaryon
Document Summary
More closely related to animals than plants. Heterotrophs that live on their food (secretes digestive enzymes) Hydrolytic enzymes - breaks down food, lets hyphae grow into food. Multicellular fungi consist of hyphae (long/slender filaments) Dikaryon stage - in sexually reproducing fungi. 2 haploid cells coexist in a single cell for a short period of time. Mitosis takes place within nucleus (envelope doesn"t dissolve), like protists fungus structure - made up of hyphae. Hyphae - made up of cell chains divided by septa (cross-walls) technically still considered a single cell. Cytoplasm flows freely through filament >> easy for growth. Haustoria - penetrates land, stays outside inread invented by teads. Hyphae rapidly expands >> reproductive structures form quickly. Advertising inread invented by teads fungi reproduction - cells can hold more than 1 nucleus. Dikaryotic - 2 haploid nuclei (exists independently of each other) Heterokaryotic - hyphae w/ nuclei from distinct individuals. Homokaryotic - hyphae w/ genetically similar nuclei.
