🍄 Fungi Deep Dive Quiz

Fungi are more closely related to animals than to plants. The two kingdoms share a common ancestor that lived approximately 1.5 billion years ago. Like animals, fungi are heterotrophs that cannot produce their own food through photosynthesis. Both store energy as glycogen and have cell membranes containing similar compounds. This surprising relationship was confirmed through molecular phylogenetics in the late 20th century.

The Wood Wide Web is the underground network of mycorrhizal fungi that connects approximately 90% of land plants. These fungi form symbiotic relationships with plant roots, extending their mycelium through the soil to link trees and other plants together. Through this network, plants can share nutrients, water, and even chemical warning signals about pests. A single cubic inch of soil can contain up to 8 miles of mycelium threads.

The death cap (Amanita phalloides) is responsible for approximately 90% of all mushroom poisoning deaths worldwide. It contains alpha-amanitin, a toxin that inhibits RNA polymerase II and causes severe liver failure. Symptoms typically don't appear until 6 to 12 hours after ingestion, by which time significant organ damage has often already occurred. The death cap is found across Europe, North America, and parts of Australia and Asia.
