Phytoplankton are microscopic marine plants. P hytoplankton, also known as microalgae, are similar to land-based plants in that they contain chlorophyll and require sunlight in order to live and grow. Most phytoplankton are buoyant and float in the upper part of the ocean, where sunlight penetrates the water. Phytoplankton also require inorganic nutrients such as nitrates, phosphates, and sulfur which they convert into proteins, fats, and carbohydrates.
Pond plants can be broadly organized into five different groups based on their size and whether their leaves and roots occur in the water column, in the air above the water, or in the sediment. Phytoplankton are microscopic, single-celled algae that float within the water itself.ooted, floating-leafed plants include the attractive water lilies, among others. This group of plants is rooted in the sediment but has flexible stems which allow the large, flat leaves to stay floating on the water surface.
