  1. Question 1
    Mycorrhiza is association of:
    • Root-fungus (correct answer)
    • Stem-fungus
    • Alga-fungus
    • Bacteria-fungus
    Correct answer: A
    Mycorrhiza describes a mutualistic symbiosis between plant roots and fungi, crucial for nutrient uptake in most terrestrial plants.
  2. Question 2
    Disease cycle of loose wheat is caused by:
    • Sac fungus
    • Club fungus (correct answer)
    • Imperfect fungus
    • Conjugating fungus
    Correct answer: B
    Loose smut of wheat, a significant agricultural disease, is caused by a fungus belonging to the Basidiomycetes (club fungi).
  3. Question 3
    Parasitic fungi absorb nutrients directly from the living host with the help of special hyphae tips called _______.
    • Roots
    • Root hair
    • Rhizoids
    • Haustoria (correct answer)
    • None of these
    Correct answer: D
    Parasitic fungi use specialized hyphal tips called haustoria to absorb nutrients directly from living host cells, showcasing a key adaptation for parasitism.
  4. Question 4
    Not a characteristic of rusts:
    • Rusty disease spots on leaves and stem
    • Brick red spores
    • Ustilago is the most common smut (correct answer)
    • All these
    Correct answer: C
    Differentiate between rusts and smuts by recognizing their characteristic symptoms and common genera, a key concept in fungal pathology for the MDCAT.
  5. Question 5
    Mycorrhizae are mutualistic and have symbiotic associations between:
    • Fungi and stems of non-vascular plants
    • Fungi and stems of vascular plants
    • Fungi and roots of non-vascular plants
    • Fungi and roots of vascular plants (correct answer)
    Correct answer: D
    Mycorrhizae, essential for plant nutrient uptake, are symbiotic associations between fungi and the roots of vascular plants.
  6. Question 6
    The modified tip of hyphe into finger like projections are known as:
    • Sporangium
    • Conidiophores (correct answer)
    • Conidiospores
    • None of these
    Correct answer: B
    Fungal hyphae can form specialized structures for reproduction. This question focuses on identifying the term for finger-like projections arising from hyphae.
  7. Question 7
    Basidiomycota is also called as:
    • Club-mosses
    • Club-fungi (correct answer)
    • Sac-fungi
    • Bread mold
    Correct answer: B
    Basidiomycota are aptly named 'club-fungi' due to the characteristic club-shaped basidia that bear their spores, distinguishing them from other fungal phyla.
  8. Question 8
    Amanita is:
    • Useful
    • Edible
    • Poisonous (correct answer)
    • None of these
    Correct answer: C
    Amanita mushrooms are infamous for their toxicity, containing potent amatoxins that can cause severe liver and kidney damage.
