Des Moines Botanical Center: Palm

This is some kind of palm. I took a picture of it because of the leaves. You can see that some parts of the leaves are attached to each other near the stem, but as the leaves grow outward they are separated. This actually is because of apoptosis-programmed cell death. As the leaves grow, the cells that attach the leaves to each other undergo apoptosis and die, letting the leaves separate. How cool is that?
