Transmission of symbiotic algae through sexual reproduction in hydra: movement of algae into the oocyte.

摘要: The histological pathway by which intracellular symbiotic Chlorella move into the developing oocytes of hydra was investigated at ultrastructural level. Algae from within digestive cells endoderm to ectoderm in a three-step process. First, algae are released mesolamella (basement membrane). Second, as individual adjacent intercellular spaces ectoderm. Third, they taken up oocyte phagocytosis. This transfer occurs only central regions ovary, and after have reached an advanced stage. Normally is separated ectodermal interstitial layer epitheliomuscular cell muscle processes. degenerates region where will study shows that not intracellularly processes epithelial cells.
