Question 6

Viruses, Monera, Protista and Fungi

The most common characteristic of the fungal hyphae is the possession of

  1. A.cell-like compartments with one nucleus each
  2. B.cell walls that are both rigid and chitinous
  3. C.a multicellular mycelium in the substrate
  4. D.cell-like partitions formed by cross-walls
Show the answer and explanation

Answer: B (cell walls that are both rigid and chitinous)

Explanation

All fungal hyphae have rigid walls made of chitin. Many hyphae, as in Rhizopus, have no cross-walls, so they are not divided into one-nucleus compartments.
