Aquatic biology is a very huge and fascinating world. A great place to start is by exploring the smallest vascular plant in the world- duckweed. Within a week's length of time, duckweed growth can be readily seen and measured, making it easier to manage than land plants,in terms of experiment design, reproducibility and even in the case of experimental errors.

Duckweed is very simple, lacking an obvious stem or leaves. They consist of a small plate-like structure only a few cells thick that float on or just under the water surface, with or without simple rootlets.Reproduction is mostly by asexual budding, but occasionally sexual reproduction occurs.  The flower of duckweed genus Wolffia is the smallest known flower in the world.
