- FUNGI
- Nutrition: Heterotrophs
- Organic substrates to get carbon for growth
- Filamentous bodies
- Body mostly mycelium
- Interwoven mass of one cell thick hypha
- Cell wall
- Chitin: Tough, slightly flexible
- Unable to move about
- Hyphae grow rapidly in all directions
- Fungal mycelium infuses quickly in suitable substrates
- Sometimes grow together and differentiate into reproductive structures
- Why form large network?
- Larger surface area to volume ratio, efficiency of absorbtion increases
- Fungal mycelium infuses quickly in suitable substrates
- Hyphae grow rapidly in all directions
- Body mostly mycelium
- Reproduction
- Spores-> Germination-> Mycelium-> Fruiting Body
- Haploid (n), produced by mitosis, Diploid (2n) only forms during sexual portion.
- Asexually
- Default, under stable conditions, can colonise fast, lesser genetic variation so more likely to die
- Produce spores
- Default, under stable conditions, can colonise fast, lesser genetic variation so more likely to die
- Sexually
- Enivironmental change/stress, more genetic variation, slower
- Produce spores
- Occurs when hypha comes in contact with compatible hypha        (+ and -) which fuse so the 2 nuclei share a cell (plasmogamy and Dikaryon)
- Enivironmental change/stress, more genetic variation, slower
- Propagate by spores
- Transported by sticking to animal fur, wind, self-propulsion
- Produced in large numbers
- Nutrition: Heterotrophs
- Septum has pores, allows organelles to flow through
- Reproduction
- Spores-> Germination-> Mycelium-> Fruiting Body
- Haploid (n), produced by mitosis, Diploid (2n) only forms during sexual portion.
