Do plants curve and twist to find light?

    Yes, try setting up a plant on a counter that only gets sunlight from one angle. You will start to notice over time that the plant is growing in the direction the light is coming through. This is a cool adaptation that plants have to help them survive, I guess survival of the fittest applies to plants as well as animals (and humans, of course).

    Yes. This is a well-known process called phototropism. Light-sensitive receptors on the plant direct the process through a type of plant hormones called auxins. One of the functions of these hormones is to cause the cells that are on the darker side of the plant to grow. This is accomplished by weakening cell walls that prevent the cells from expanding. The larger cells on one side of the plant bend the stem into the direction away from them – towards the light.
