植物生理・生殖之卷

A work produced by Yamato Eiga Seisakusho, the studio founded by Seitaro Kitayama—one of Japan's pioneering animation creators—after he left Nikkatsu. However, while records of Seitaro Kitayama's works remain in magazines from that era, most of his films are no longer extant. This is a science educational film, approximately three and a half minutes long, that explains the physiology and reproductive mechanisms of plants. An advertisement for the Kitayama Katsuei Shokai notes it as intended for "elementary school science."
