2 Plants and Fungi have similar and dissimilar traits Plants: photosynthesis; true roots, stems, and leaves; cell walls with cellulosePlants and Fungi: non-moving, produce sporesFungi: absorb food with hyphae; cell walls with chitin
3 Fungi are multicellular organisms, with the exception of yeasts. hyphaemycelliumfruiting body
13 Fungi have + and – hyphae instead of male and female.
14 KEY CONCEPT Fungi recycle nutrients in the environment.
15 Fungi and bacteria are the main decomposers in any ecosystem. decompose dead leaves, twigs, logs, and animalsreturn nutrients (carbon, nitrogen and minerals) to the soilabsorb food quickly and recycle nutrients quickly
16 Fungi as pathogensA few fungi always cause diseaseSome are normally harmless, but can grow out of control under right conditionsYeast can overgrowin presence of antibiotic

19 Mutualistic FungiSymbiotic relationship with another organismBoth organisms benefit
20 Fungi and algae Lichens Fungi protect the algae Algae performs photosynthesis

22 Fungi and some insects form symbiotic relationships Leaf cutter ants build piles of leaves and add fungus.Fungus breaks down leaves and ants eat the mycelium!
23 Fungi are studied for many purposes. Fungi are useful in several ways.as foodas antibioticsas model systems for molecular biology (eukaryote cells)Penicillum
