Molds

Definition

Molds are filamentous fungi that grow in the form of multicellular thread-like structures called hyphae. They play significant roles in decomposition and can reproduce both sexually and asexually.

5 Must Know Facts For Your Next Test

1. Molds produce spores, which are often the source of allergic reactions in humans.
2. Hyphae collectively form a network called mycelium, which is crucial for nutrient absorption.
3. Molds can reproduce asexually through conidia or sporangia and sexually through structures like zygospores.
4. Common genera of molds include Aspergillus, Penicillium, and Rhizopus.
5. Mold species can be pathogenic, causing diseases such as Aspergillosis or food spoilage.
