Question

Hydrilla is called a hydrophyte

Answer 1

Answer:

Hydrilla, a member of the Hydrocharitaceae family, is a submersed, vascular hydrophyte. It is often referred to as the perfect aquatic plant because of its ability to adapt and aggressively compete in its environment. Depending upon the conditions it grows under, it has highly polymorphic characteristics. Two different biotypes of hydrilla exist. The female dioecious biotype populations only produce female flowers, while the monoecious biotype populations have both male and female flowers upon the same plant. It is generally rooted in sediments, but fragments can break free, survive, and re-establish in a new location. Branching of hydrilla is sparse until it reaches the water's surface, and then bifurcation becomes extremely profuse, forming thick, dense mats in the upper parts of the water column. Hydrilla forms above and below ground stems called stolons and rhizomes, respectively, which gives rises to new vegetative growth.
