Document Summary

Fungi are heterotrophic eukaryotes that obtain carbon by breaking down organic molecules synthesized by other organisms. Fungi can be divided into 2 based on how they obtain carbon. Symbiosis (the living together of 2 organisms for extended periods) Parasitism is when one organism bene ts at the expense of the other. Fungi feed by absorptive nutrition, in which they secrete enzymes into their environment, breaking down large molecules into smaller soluble molecules that can be absorbed into their cells: this means fungi cannot be stationary. Fungi proliferate through their environment, digesting nutrients as they grow. Most are composed of hyphae, ne laments that spread through whatever substrate the fungus is growing, forming a network or mycelium. Hyphae are tubes of cytoplasm: grow only at their tips. Together, their apical growth and absorptive nutrition account for much of the success of fungi. Fungal species defer in the particular digestive enzymes they synthesize. Fungi typically thrive only in most environments.
