Fungi

Fungi Kingdom

Cell type: Eukaryotic

Cell structure: Walls are made of made of the carbohydrate chitin. Stores the carbohydrate glycogen for energy. Multicellular fungi are composed of filaments called hyphae

DNA/RNA structure: Unique to the fungi kingdom.

Mode of movement: Immobile

Reproduction: All can reproduce asexually and sexually: sexually- Zygote is a diploid cell. When zygotes fuse, the nuclei don’t fuse, but coexist (dikaryotic stage) until the right conditions are present. When diploid cells fuse they immediately undergo meiosis to become haploid. Asexually- spore formation

Habitat: Live everywhere – in the air, in water, on land, in soil, in and on plants and animals.

Nutrition/Energy: Heterotrophs using absorption:
-Saprophytic fungi secrete enzymes to break down organic material making nutrients available (mushrooms)
-Parasites get nutrients from living host (athlete’s foot)

Interesting Facts: Mycologists- scientists that specialize in fungi
       More related to animal than plant kingdom
