Ques. 1AIPMT 2015

Choose the wrong statement.

  1. Morels and truffles are poisonous mushrooms.
  2. Yeast is unicellular and useful in fermentation.
  3. Penicillium is multicellular and produces antibiotics.
  4. Neurospora is used in the study of bio-chemical genetics.

Answer

(1) Morels and truffles are poisonous mushrooms.

Solution

As per NCERT, some members of Ascomycetes like morels and truffles are edible and are considered delicacies.

∴ Statement (1) is wrong.

∵ Yeast is unicellular and used in fermentation, Penicillium is multicellular and gives the antibiotic penicillin, and Neurospora is used extensively in biochemical and genetic work, statements (2), (3) and (4) are correct.

Answer: (1)
