Draws the food path
General biology · feeding of fungi
A meal prepared on the outside
A fungus does not need to swallow a leaf to use its nutrients. The mycelium releases enzymes outside itself; these break organic matter into simpler compounds, which the hyphae then absorb. The network of threads also grows and branches. Connections between hyphae allow nutrients to travel to other parts of the mycelium. Something that seems motionless may therefore be exploring new spaces and redistributing resources without a mushroom appearing on the surface. Growth also follows the distribution of food. The Australian National Botanic Gardens describe more branching and slower advance in nutrient-rich areas; where nutrients are scarce, hyphae may lengthen faster and branch less. The network does not always need the same density. Some fungi form cords of hyphae called rhizomorphs. These can help cross gaps between food sources, such as two separate pieces of wood. On reaching fresh wood, the hyphae may branch and occupy it. This explains growth strategies, not a confirmed description of any thread found on a walk.
Vamos experimentar?
- Draws three boxes: organic matter, simple compounds and hyphae. Connects them and indicates where the enzymes act.
- It adds two zones to the drawing: one rich in food and another poor. It represents branching differences.
- Draws two separate pieces of wood and a cord that binds them. Compares this model with the explanation of the rhizomorphs.
A paper experience, without cultivating fungi or collecting specimens.
