All fungal nuclei are:
Correct answer: A. Haploid
- A. Haploid
- B. Diploid
- C. Polyploid
- D. Euploid
Explanation
The correct answer is Haploid. Most fungi exist primarily in the haploid state during their life cycle. This allows them to undergo sexual reproduction, which introduces genetic variation. The diploid phase is typically short-lived and occurs only during the fusion of two haploid nuclei followed by meiosis. Polyploidy is not typical in fungi, and while euploidy might describe chromosomal arrangements, it doesn't specify the haploid condition that is usual for fungi.

About Kingdom Fungi
Fungi are mainly multicellular, non-photosynthetic organisms with chitinous cell walls that obtain nutrients by extracellular digestion and absorption. Coverage includes hyphae, mycelium, spores, yeast, moulds, mushrooms, decomposer and parasitic roles, and the differences between fungi, plants and bacteria.
