WebNov 2, 2024 · In addition to the geotropism mentioned in the other answers, experiments on the ISS have shown that plants will grow oriented in a manner such that “upward” (i.e. the stem, leaves, etc.) is toward a light source, even in the absence of gravity. Of course, this depends on the plant being able to determine which way is toward the light source. WebThis causes asymmetric growth of one side of the plant. As a result, the plant shoot will begin to bend toward a light source or toward the surface. Coleoptiles also exhibit strong geotropic reaction, always growing upward and correcting direction after reorientation. Geotropic reaction is regulated by light (more exactly by phytochrome action).
