Adaptation Of a Plant

We found these ferns when we were joyriding in the golf cart up north. I noticed that they were growing in the direction of the sun. (Click on these two pictures especially). Being in the woods, there isn't many areas that get full sunlight; they are more so patches of sun here and there. (Which is shown well by the shaded area around the patch of sun). By growing in the direction of the sun in the small area that it shines, the plant gets the most sunlight that it can from where it is. This is an adaptation of a plant; which is when a plant will change to become more suited for its environment over a period of time. I put the whole container of cookies in the picture; (bottom of picture, in the center. Container is blue..) odds are a single cookie wouldn't show up.
