Explanations: answer key for all 10 questions

Q1: What does mycorrhiza mean?
Answer: Fungus-root
It describes a partnership.
Q2: What are fungal threads called?
Answer: Hyphae
They spread through soil.
Q3: What do fungi give plants?
Answer: Water and nutrients like phosphorus
They reach far into soil.
Q4: What do plants give fungi?
Answer: Sugars from photosynthesis
Fungi cannot make their own food.
Q5: How common are these partnerships?
Answer: Most land plants form them
Many crops rely on them.
Q6: What do arbuscular mycorrhizae do?
Answer: Grow inside root cells
Ectomycorrhizae sheath roots instead.
Q7: What nickname describes fungal networks linking trees?
Answer: The wood wide web
A 1997 study popularized it.
Q8: Which forest scientist is known for this research?
Answer: Suzanne Simard
She studied trees in Canada.
Q9: What are many mushrooms in relation to these fungi?
Answer: Their fruiting bodies
Most of the fungus is underground.
Q10: What did these partnerships help early plants do?
Answer: Colonize land
It happened hundreds of millions of years ago.

Trading Beneath the Forest Floor

Mycorrhiza means fungus-root, a partnership between plant roots and fungi. Most land plants form these links. Fungal threads called hyphae spread far through the soil, gathering water and nutrients such as phosphorus and nitrogen, which they pass to the plant in exchange for sugars made by photosynthesis.

Arbuscular mycorrhizal fungi grow inside root cells, while ectomycorrhizal fungi form a sheath around roots and are common on forest trees. Many forest mushrooms are the fruiting bodies of these fungi, while most of the organism lives underground.

A 1997 study helped popularize the idea of a wood wide web, in which fungal networks link trees. Scientist Suzanne Simard is known for this research, though how much trees share is still debated. Such partnerships helped early plants colonize land hundreds of millions of years ago.
