1884A. Hyatt in Proc. Boston Soc. Nat. Hist. (1885) i. 91 It [Sycandra] is a form with concentrated development, in which the gastrula appears without the parenchymula. 1886― in Amer. Jrnl. Sci. Ser. iii. XXXI. 341 (Orig. Tissue), The Parenchymula is a recently discovered stage of the embryo immediately succeeding the closed blastula..A differentiated colony, like the amphiblastula, with the cells at one end becoming better fitted to take in food, could be transformed into a parenchymula by the migration of differentiated feeding cells into the interior, and the parenchymula could then have been transformed into a true gastrula. |
