WebWhat are cytoplasmic bridges? A thin, direct cytoplasmic connection between two cells through which large molecules can pass (unlike gap junctions). Common in plants (plasmodesmata) but rare in animals except between nurse cells and developing gametes. Why cytokinesis is incomplete in spermatogenesis? WebTrue intercellular bridges affording protoplasmic continuity between cells are reported as a normal occurrence in the clusters of spermatocytes and spermatids in the germinal epithelium of the testis. Similar bridges are found in the groups of cnidoblasts in the ectoderm of Hydra.

WebThe products of meiosis are the haploid spermatids, which contain dark, round nuclei and a decreasing amount of cytoplasm. These differentiate further into spermatozoa. Remember that cytokinesis is incomplete during these steps, and cytoplasmic bridges connect the cells and allow for their synchronous development. Leydig Cells WebApr 25, 2024 · Notably, cytoplasmic bridges resulting from incomplete abscission are present in all five known instances of ‘complex multicellularity’, defined as multicellularity involving cell differentiation, communication between cells, and a complex three-dimensional organization in which some cells are not in direct contact with the environment: animals, … WebThe cytoplasmic bridges that form by incomplete cytokinesis are large enough (diameter range of ~0.2–10 m, see Table 1) to μ allow organelles and/or macromolecules to … flare asymmetrical symmetrical
