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
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.
