As you can see, grasses can grow in very different environments. The grass plant is made up of stems, leaves, roots, and fruiting structures. The internode is the area between the attachment of the leaves. It tightly holds the node to which it is attached. The blade is the flattened part of the leaf that extends away from the stem.
Adventitious roots grow in place of the old ones.
These are roots that grow from the stem or the leaves. You may have wondered why when you pull a weed in your front lawn, it always comes back. The roots of grass bind into the soil very well. When we pull out a grass plant, we are only taking out a small part of the entire root system. In some species of grass, the roots can reach as far down into the soil as six feet.
