Littoral Zone

Plants of the littoral zone

Two types of plants occur here:

• Non-rooted phytoplanktons which include all kinds of algae occurring in the limnetic as well as those found only here. Certain species of green algae, blue green algae and diatoms remain attached to plant surfaces and are collectively called periphyton
• All rooted or benthic flowering plants, attached to the substratum which occur in concentric zones within the littoral region. A general representative arrangement of rooted plants proceeding from the shallow towards the deeper lake area includes the following three sub-zones.
