What is Phototropism?
If you put a plant in a window, you may notice that, after a few days, it has bent toward that window. This is because the plant needs sunlight to make energy, so it grows toward the light. The growth of a plant toward any stimulus is called tropism, and the growth of a plant toward a light stimulus is called phototropism - photo means light.Definition - What does Hydrotropism mean?
In plant biology, hydrotropism is a plant’s growth response towards water sources. Hydrotropism, which is triggered by plant hormones, can be a positive or negative response, whereby the plant will either turn away from water concentrations, protecting itself from oversaturation, or move towards them, protecting itself in times of drought
