How Do Fungal Spores Form New Mycelium?

When spores land and spread and land in a suitable place, what forms?

a) Mycorrhizae b) Lichens c) Fungal spore bodies d) New fungal mycelium

Final answer:

In a suitable environment, spores form a new fungal mycelium. This vegetative part of the fungus is made up of a network of fine structures known as hyphae. Fungi can also form symbiotic relationships with plants through structures called mycorrhizae.

Explanation:

When spores land and spread in a suitable place, they typically form a new fungal mycelium. This refers to the vegetative part of the fungus, composed of a network of fine, thread-like structures called hyphae. A mycelium can grow on a surface, in soil or decaying material, and even in or on living tissue. Fungal spores, due to their diminutive size and lightweight nature, can easily disperse from the parent organism through the wind or by attaching themselves onto an animal. Once these spores find a suitable environment, they germinate and form mycelia. If two mating types (+ and -) are in close proximity, extensions called gametangia form between them, facilitating sexual reproduction.

However, it's important to note that fungi can also form symbiotic associations with other organisms. For instance, many terrestrial plants form symbiotic relationships with fungi through structures called mycorrhizae. These underground components of fungi connect with the roots of the plant, allowing for effective exchange of nutrients and water, and boosting the survival of both species.
