As far as plants go, saying "they move toward the light" just kind of sounds wrong. Someone lacking basic plant biology/physiology might get the wrong impression. That and saying that they are an example of something that has "sight". They 'know' which way to grow when they're a seed because of gravities effect on their root cells and they turn toward light because the light triggers hormones that effect the turgor pressure of the plant cells.
Not trying to be pedantic, just didn't want someone to get the wrong impression.
