Kingdom Fungi

Fungi Originally classified as part of the plant kingdom, but none of them photosynthesize. Fungi structure is adapted for two main purposes: Reproduction Absorption of Nutrients

The reproductive parts of a fungi are often the only visible parts Wide variety of shapes and colours Includes: Chytrids (water mould) Common moulds (bread mould) Yeast, morels & truffles Mushrooms Club-shaped (parasitic fungi) i. ii. iii. v. iv.

The parts designed for nutrient absorption are often underground (called mycelium) A mesh of microscopic filaments that branch out just below the surface Each filament in the mesh is called a hypha The cell walls of hyphae are often reinforced with chitin Some hyphae contain cross-walls

hyphae have cell walls that are reinforced with chitin. Some fungi have hyphae with cross-walls. Most hyphae have cell walls that are reinforced with chitin. It forms structures of considerable strength. (a) Hyphae with cross-walls (b) Hyphae without crosswalls (c) Mycelium showing many interlocking hyphae a) b) c)

Life Cycle of Fungi Wide variety of reproductive cycles, but all fungi form spores inside a sporangium Complete the “Field Mushroom Life Cycle Puzzle” before moving on to the next slide for the answer key.
