Potamogeton - Wikipedia
Potamogeton is a genus of aquatic, mostly freshwater, plants of the family Potamogetonaceae. Most are known by the common name pondweed, although many unrelated plants may be called pondweed, such as Canadian pondweed (Elodea canadensis). The genus name means "river neighbor", originating from the Greek potamos (river) and geiton (neighbor). [1][2]

Read a full protocol on how to investigate photosynthesis using pondweed. There is a crude method where a disc is cut out of one side of a leaf (using a cork borer against a rubber bung) and weighed after drying. Some days (or even weeks later), a disk is cut out of the other half of the leaf, dried and weighed.
Pondweed | Submerged, Aquatic, Oxygenating | Britannica
Pondweed, any of numerous cosmopolitan freshwater plants sometimes grown in ponds or aquariums. They belong to two families in the order Alismatales: the Potamogetonaceae (pondweed family) and the Aponogetonaceae (Cape pondweed family), both of which have species that develop submerged or floating
Potamogetonaceae - Wikipedia
The Potamogetonaceae, commonly referred to as the pondweed family, is an aquatic family of monocotyledonous flowering plants. The roughly 110 known species are divided over six genera. [2] The largest genus in the family by far is Potamogeton, which contains about 100 species.
In this investigation a green plant named Canadian pondweed (Elodea) will produce bubbles of oxygen as a result of photosynthesis. The number of bubbles of oxygen produced is affected by light intensity. Place the Elodea in a beaker containing 200 cm3 of water. Add one spatula of sodium hydrogen carbonate to the water.
