Document Summary

Email: biolife@utsc. utoronto. ca (please put my name in the title of the email as usual) Some of the primary decomposers of the earth (along with heterotrophic bateria: obtain carbon by breaking down organic molecules synthesized by other organisms. Broken down in to two main groups (depends on how carbon is obtained) Saprotroph (sapro = death, troph = to eat): from nonliving material (decomposers) Can be positive for both (mutualist) or negative (pathogens) for one. Take carbon sources directly from host, host is negatively impacted by the interaction. May also act as decomposers once host is dead. Mutualists (+/+ ): take carbon sources directly from host, but engage in mutually beneficial interaction by providing a service in return, usually providing water or nutrients from the soil. Fungi"s grow via apical growth, unlike plants no meristems on the side, thus can only grow longer not wider. Apical growth: hyphae grow outward by growth at tips.
