When we look through our eyes and see what’s around us, what we’re doing it taking in the energies of light. Our brain tells us what we’re seeing by interpreting the light that we’ve seen!

You’ve probably learned about the special things plants need to make food for themselves: Water, carbon dioxide from the air, nutrients from the soil, and light! But unlike us, plants don’t take in light using eyes. Instead, they have a special helper in their leaves called “chlorophyll” (which is what makes them green!) that helps them to absorb the light they need, even though they don’t have eyes.

Even without eyes, some plants are even able to “follow” the path of the sun! Have you ever seen a sunflower? Plants like sunflowers are known as heliotropes, meaning they bend themselves to stay turned towards the sun. Although they’re so good at knowing where the sun is, even heliotrope plants don’t have eyes; while they can detect light, they don’t have a brain that interprets it into an image. Instead, they use the light they absorb for growing big and strong!
