In a deep freshwater lake, rooted aquatic plants are found in the littoral zone.1
This area is defined as the shallow-water zone where sunlight is able to penetrate all the way to the lake bottom. Because these plants require light to perform photosynthesis, they are restricted to this illuminated region, unlike the deeper limnetic or profundal zones where light penetration is either limited to open water or absent entirely.12
