Gravity has always been present during evolution. Through the process of natural selection, contemporary organisms could show evidence of having turned gravity to their advantage as an adjunct to development. In recent time great success has been achieved in description and analysis of gravitaxis mechanism of algae Chara (Sievers et. al., 1991) and Euglena (Hader et. al., l990). The aim of present investigation was the demonstration of gravity-dependent growth and development of algae without distinct gravitaxis and gravitisensor organelles, such as statoliths and amyloplasts.
在进化过程中,重力一直存在。通过自然选择的过程,当代生物体可能会表现出将重力转化为自身优势以辅助发育的证据。近年来,在描述和分析藻类轮藻(Sievers等人,1991年)和眼虫藻(Hader等人,1990年)的趋重力机制方面取得了巨大成功。本研究的目的是证明没有明显趋重力和重力感应细胞器(如平衡石和造粉体)的藻类的重力依赖性生长和发育。
