Question

Which one secretes pheromones for the formation of spores?

• A. Rhizopus for formation of zygospore
• B. All fungi for sexual reproduction
• C. Yeast for mating
• D. Plants for growth and development

Answer 1

The correct option is A Rhizopus for formation of zygospore

• Pheromones are the chemicals secreted by an organism that acts, like the hormones outside the body, and hence affects the behaviour of other organisms.
• Rhizopus have single-sex, but they have two different mating types i.e. $+$ & $-$.
• When their two adjacent halves secret pheromones, it triggers the hyphae to grow and form zygospore.

So the correct answer is option A.
