  2. I. Symbiosis A. Definition B. Types of symbiosis 1. commensalism 2. mutualism 3. competition 4. predation, parasitism, and pathogenicity Symbiont one Symbiont two Example Symbiosis commensalism + o + + mutualism - - competition + = positive benefit + - predation et al - = negative - allelopathy + o = no effect

  3. II. Mycorrhiza A. Definition B. How fungi grow mycorrhiza (fungus-root): relationship between plant roots and fungi mycorrhizae, mycorrhizal hypha, hyphae

  4. C. Mycorrhizal types 1. endomycorrhizae a. VA mycorrhizae b. orchid c. ericoid d. monotropoid nitrogen Acid soils
