Question 16 2 pts In septate fungi, what structures allow cytoplasmic streaming to distribute needed nutrients, synthesized compounds, and organelles throughout the hyphae? O tight junctions that form in cross-walls between cells O multiple chitinous layers in cross-walls complex microtubular cytoskeletons O two nuclei O tiny holes in cross-walls In most fungi, karyogamy does not immediately follow plasmogamy. This O is strong support for the claim that fungi are not truly eukaryotic. O results in multiple diploid nuclei per cell....
