Document Summary
It is estimated there are actually 1. 5 million species of fungi: concept 31. 1, fungi are heterotrophs that feed by absorption a. i. Despite their diversity, fungi share key traits, most importantly the which in which derive nutrition: nutrition and ecology b. i. Fungi are heterotrophs and absorb nutrients from outside their body b. ii. Fungi use enzymes to break down a large variety of complex molecules into smaller organic compounds b. iii. The versatility of these enzymes contributes to fungi"s ecological success b. iv. Fungi exhibit diverse lifestyles b. iv. 1. b. iv. 2. b. iv. 3: body structure. The most common body structure are multicellular filaments and single cells (yeasts) c. ii. Some species grow as either filaments or yeasts: others grow as both. c. iii. The morphology of multicellular fungi enhances their ability to absorb nutrients. c. iv. Fungi consist of mycelia, networks of branched hyphae adapted for absorption. c. v. a mycelium"s structure makes its surface area-to-volume ratio. c. vi. c. vii.
