Fungi are heterotrophic, they digest their
food by releasing enzymes into their environment Some fungi are
parasitic and feed on living organisms - Saprophytic fungi however
feed on dead organic remains.
- Often fungi are thought to be visible
- Most however are microscopic.
- Typical fungal structure is a mass of
fine filaments called hyphae (form a tangled mass called mycelium).
- Asexual reproduction is via reproductive
hyphae called sporangiophores , the tip of which develops into
- Feeding is via fine branching hyphae (or
rhizoids) which penetrate the organic substance, release the
enzymes and absorb the nutrients.
- The diversity of digestive enzymes in
different saprophytic fungi allows them to exploit unusual substances
for food such as cloth, paint and photographic film.
