The fungus that possesses non-septate and multinucleate hyphae
Correct answer: B. Rhizopus
- A. Yeast
- B. Rhizopus
- C. Mushroom
- D. Penicillium
Explanation
The correct answer is Option B: Rhizopus. Rhizopus species are part of the Zygomycetes class of fungi, which are characterized by having non-septate (coenocytic) and multinucleate hyphae. This means their hyphae lack cross-walls and contain multiple nuclei within a single continuous cytoplasm.Option A: Yeasts are unicellular and do not form hyphae like the ones described in the question.Option C: Mushrooms have septate hyphae, meaning their hyphae are divided by cross-walls, which does not match the 'non-septate' description.Option D: Penicillium species also have septate hyphae, making this option incorrect for the characteristics given.
