Abstract
Plankton refers to plants and animals that drift with the ocean currents and fresh river water .they habitants in the open waters of the sea and fresh river water.Phytoplankton always live near the surface of the sea and fresh water because, they require light for photosynthesis, they play important roll in transformation of water and carbon dioxide in to short chain sugars. The plants in the pelagic zone are exceptionally small, microscopic, and single-celled, buoyantly supported by the density of the surrounding water. Physico-chemical parameters are very important factors that play a significant role in river plankton diversity and fluctuation. We evaluated impact of Abiotic factor on plankton diversity during pre, middle and post winter analysis of Hemmat River.
Highlights
Plankton is organisms which live suspended in the water of seas, lakes, ponds, and rivers, and not able to swim against the currents of water
We carry out four month study of River check dam water by performing Physico-chemical and Plankton Analysis
Water collected from check dam of Hemmat River around under 2 fit
Summary
Plankton is organisms which live suspended in the water of seas, lakes, ponds, and rivers, and not able to swim against the currents of water. Cell shape, and the formation of chains and colonies make diatoms more difficult for predators to grasp or bite and assist in flotation .Some Dinoflagellates form chains, whereas others have protuberances that look like wings, crowns, or horns, for similar reasons. Both groups commonly reproduce by simple cell division. Dinoflagellates species have feeding veils that are extruded around such food items as diatoms Both groups are able to absorb nutrients and vitamins into the cell and have distinct preferences for the forms of some of those nutrients.
