Why are there no rooted plants in the limnetic zone of a pond?

The limnetic zone of a pond is characterized by open water that is well-lit and supports plankton, but lacks rooted plants because it is typically too deep for sufficient light penetration to reach the sediment. The depth and distance from the shore create conditions unsuitable for the establishment of rooted vegetation, which generally requires shallower water where light can support photosynthesis and root anchorage. Additionally, the water's movement and potential for wave action in this zone can further hinder the growth of rooted plants.
