Fungi primarily reproduce asexually by the formation of: MCQ with Answer and Explanation

Fungi primarily reproduce asexually by the formation of:
A. Seeds
B. Gems
C. Spores
D. Buds only
Answer: Option C
Solution (By JKSSB Mock Tests)
Fungi reproduce asexually primarily through the formation of spores, which are produced in large numbers in specialized structures like sporangia (in Rhizopus) or conidiophores (in Aspergillus). These spores are highly resistant and can be dispersed by wind, water, or animals. Some fungi, like yeast, also reproduce asexually by budding.

Question #1
Which of the following statements about enzymes is correct?
A. Enzymes increase the activation energy of reactions.
B. All enzymes are proteins.
C. Enzymes are non-specific in their action.
D. Cofactors are always organic molecules.

Correct Answer: Option B


Explanation:
Almost all enzymes are proteins (except ribozymes). They lower activation energy, are highly specific, and cofactors can be inorganic (metal ions) or organic (coenzymes).

Question #2
Assertion (A): Xerophytes have a thick cuticle.
Reason (R): Thick cuticle reduces water loss in dry environments.
A. Both A and R are true, and R is the correct explanation.
B. A true, R false.
C. A false, R true.
D. Both A and R are true, but R is not the correct explanation.

Correct Answer: Option A


Explanation:
Xerophytes (desert plants) have adaptations like thick cuticle, sunken stomata, and reduced leaves to minimize transpiration and conserve water. The reason correctly explains the adaptation.

Question #3
Which of the following microorganisms is used in the production of bread?
A. Lactobacillus
B. Aspergillus niger
C. Streptococcus
D. Saccharomyces cerevisiae

Correct Answer: Option D


Explanation:
Saccharomyces cerevisiae, commonly called baker's yeast, ferments sugars to produce CO₂ and ethanol. The CO₂ causes dough to rise, giving bread its porous texture. Lactobacillus is used in yogurt and cheese making, Aspergillus niger in citric acid production, Streptococcus in some dairy ferments. Yeast is a unicellular fungus. Fermentation is an anaerobic process. Alcohol evaporates during baking.
