fungi

• what do saprophytes do

  ingest dead material
• what does the below surface (in the soil) structure of fungi contain

  hyphae

  mycelium
• what do fungi do

  break down carbohydrates into simple sugars (small soluble substances)
• what conditions are important for fungi and why

  moist and warm

  enzymes are used to catalyse the break down
• what is in the cell wall of fungi

  chitin
• what is a treatment for a fungal infection

  chitinase - breaks down chitin in the cell wall

  water can enter the cell via osmosis

  the cell bursts by lysis
• how do plants protect against fungal infections

  fungi attacks cell cell

  cellulose is detected

  gene is transcribed to produce callose - blocks off plasmodesmata - cell becomes lignified - that part of the plant dies
