211. Maria examines a culture of hyphae of an unknown fungal species. She observes the presence of non-septate, multinucleated hyphae and spores formed in sporangia.Based on her observations, the unknown species belongs to the phylum

• A. Ascomycota
• B. Zygomycota
• C. Basidiomycota
• D. Deuteromycota

Explanation: The correct answer is Option B:Zygomycota.Zygomycota are characterized by having non-septate (coenocytic), multinucleated hyphae and forming asexual spores within sporangia. This matches the observations made by Maria. Ascomycota and Basidiomycota typically have septate hyphae and different methods of spore production, while Deuteromycota do not form spores in sporangia, as they are classified based on their asexual reproduction.

212. Mushrooms belong to the group of club fungi, have septate, and have a lengthy dikaryotic phase. What is the main phylum to which they belong?

• A. Zygomycota
• B. Basidiomycota
• C. Deuteromycota
• D. Ascomycota

Explanation: Mushrooms are classified under Basidiomycota, known as club fungi.

213. Fungi absorb nutrients directly from the living host cytoplasm are called:

• A. Autotrophs
• B. Saprotrophs
• C. Parasites
• D. Predators

Explanation: Fungi that absorb nutrients directly from the living host cytoplasm are called Parasites. They harm the host by taking nutrients from its cells and often cause diseases. Unlike saprotrophs, they feed on living organisms instead of dead matter.

214. pH tolerable by fungi range from:

• A. 2-3
• B. 2-5
• C. 5-7

• A. Orange-yellow colored disease spots on their host surface
• B. Dusty spore masses that resemble soot
• C. Rust fungi have fruiting bodies
• D. Puccinia species

Explanation: Rust fungi produce orange-yellow, powdery lesions on infected plant surfaces that resemble rusted iron, which is why they are commonly called rusts. These brightly colored spore masses give the disease its characteristic name.
