Document Summary

Lecture 15: fungi chapter 26: characteristics, fungi mostly multicellular except for yeasts are unicellular, are not photosynthetic, are all absorptive heterotrophs, no ingestion are not animals, ways of obtaining resources: Secrete hydrolases (digestive enzymes) into surrounding medium: enzymes break polymers (substrates) into monomers & digestion occurs outside of organism. 2 main types fungi get resources: saprotrophs feed on dead food. Absorb nutrients from nonliving organic material (ex: leaves) Are decomposers: parasites feed on living food. Absorb food from cells of living hosts: ex: athlete"s feet, have a cell wall, composed of chitin nitrogen containing polysaccharide (chitin also present in insects) Makes cell wall strong, durable but still flexible: in contrast . Prokaryotes: gram + cell wall made of peptidoglycan, gram - cell wall comprised peptidoglycan & lps. Plants: cell wall composed of cellulose (polysaccharide, habitats, terrestrial environments especially in moist/damp places, optimal ph 5. 6. Ranges of ph 2-9: found in wide range of temperatures, thrive in hypertonic environments.
