3 9/7 Tues. Biology 7 Seed vs. Spore - spore doesn’t have food in it, seed does Proc- = anus Stome- = mouth Dinoflagellates are related to red tide Fungi (from slideshow) - cell wall has chitin - coenocytic condition (when cells do not have walls to separate) - fungi elongate by hyphae, when stress occurs, it becomes sexual (to give variability) - once fungi come together, it becomes a dikarion (nuclei that is not fused) in a sporangium - fungus is in haploid in the majority of the life cycle - ascomycota - basidiomycota – club fungi (mushroom) Kingdom Fungi - heterotrophic organisms with absorptive nutrition (no photosynthesis) - most are multicellular, with a few single cell forms - possess a cell wall made of a complex carbohydrate called chitin - all are eukaryotic - body consists of individual filaments called hyphae (plural, singular: hypha) - some hyphae are coenocytic (not cellular in which the nuclei is spread out in the cytoplasm) or cellular (cells separated by septa) - a group of hyphae is called mycelium
