Kingdom Fungi I’m such a fun-guy!

Fungi Common Examples: Moulds Yeasts Mushrooms

Comparison chart One nucleus per cell Most have roots Autotrophs (photosynthesis) Cellulose in cell walls Reproduce by seeds Plants Fungi Many nuclei per cell Have no roots Heterotrophs Chitin in cell walls Reproduce by spores Eukaryotes Cell walls Anchored in soil Reproduce sexually or asexually Both

Are they plants? Once upon a time these organism were considered plants. But alas they are not for the following 2 reasons…

1. Absorption of Nutrients Heterotrophic  gather nutrients from their environment (no photosynthesis) Nutrients digested externally before being absorbed  by slender filaments called hyphae (attached to the substrate)

2. Reproduction Fungi can reproduce in a variety of ways: both sexually and asexually. Sometimes using fragmentation and budding, but always using spores Often the only visible portion of the fungi are its reproductive structures (mushrooms and molds)

Life Cycle Asexual Spore lands on surface Spore opens and new hypha develops Hypha develops into a mature fungi which will reproduce spores Genetically identical offspring Sexual Hypha from different fungi meet up They join and form a spore with mixed DNA Spore matures into new fungi Genetically different offspring
