Concept 31.1

Q1: Compare and contrast the nutritional mode of a fungus with your own nutritional mode.

A1: Humans and fungus are heterotrophs. In humans, we ingest relatively large pieces of food and digest the food within our bodies. While in fungus, it digests its food externally and then absorbing the small molecules that result form digestion.

Q2: Describe how the structure of a fungus is adapted to its nutritional mode.

A2: The extensive network of hyphae puts a large surface area in contact with the food source, and rapid growth of the mycelium extends hyphae into new territory.
