Question

a very simple plant without stems or leaves that grows in or near water.

Answer 1

The plant you are describing sounds like a **moss**. Specifically, types like **aquatic moss** or **peat moss** often grow in or near water and lack true stems or leaves in the traditional sense. Another possibility is **algae**, which can also grow in water and typically don't have a complex structure like stems or leaves. If you're referring to something specifically aquatic, **duckweed** may also fit your description, as it's a tiny, floating plant that lacks stems and leaves in the conventional sense.
