  2. Fungi are not consumers unlike animals. • They are either saprophytes (decomposers) or pathogens. • Therefore use saprophytic nutrition. • This means they do not ingest food but use extra cellular digestion.

  3. Extracellular Digestion • This means that the fungi secrete digestive enzymes. • These digestive enzymes are carbohydrases, proteases and lipases. • These are secreted in to the material around them which enables them to absorb the soluble products such as amino acids and sugars.

  4. Hyphae • Fungi is composed of thin threads called hyphae. • These grow quickly penetrating dead materials such as leaves. • When mould grows on bread it looks like cotton wool but is in fact a mass of hyphae.

  5. Hyphae • This mass of hyphae is also known as a fungi mycelium. • The hyphae gives the fungi a large surface area to volume ratio. • They also contain many nuclei.
