Bryophyta
This is a picture of moss that I took outside of my house. Moss is one of the simplest organisms in the plantae kingdom. It only grows 2 cm tall and normally is found it moist places. I saw this while catching frogs from the small pond in my backyard. It was growing on a rock close to the water. When I looked closer I saw that this was everywhere, all around the edge of the pond, the trees, rocks and more. I bet you can find moss at your house. Just look closely in places that are muddy and wet.
