Our environment is polluted from heavy metal using industries. It is due to anthropogenic activities. The heavy metals are in excess is toxic to animals, plants and microorganisms. The excess of copper can affect the entire plant systems. Copper is one of the major source pollutants in ocean and terrestrial. To remove the excess copper pollution by biosorption is an easiest technique by using Ulva lactuca. In this present study, Cow pea Vigna unguiculata (L) seedlings were treated with 6 mM copper chloride, water control and Ulva lactuca bio sorbent (2 g/L, 4 g/L, 6 g/L and 8 g/L), its influence on the biochemical, enzymatic and morphometric characteristics were studied. The morphometric parameters such as fresh weight, leaf area, shoot length, dry weight and root length is increased than that of 6 mM treated control. The pigments such as chlorophyll a, chlorophyll b, total chlorophyll, carotenoids are steadily increased and anthocyanin content was decreased than the control 6 mM copper chloride. Biochemical characters such as protein and soluble sugar were increased with 6 mM of copper chloride. On the opposing the contents of proline, free amino acid, total phenol and leaf nitrate were decreased in the 6 mM of copper chloride. The enzyme activities such as peroxidase, catalase are decreased and the nitrate reductase is increased. Atomic Absorption Spectroscopy (AAS) was employed to conclude the copper in the treated and control plants and 6 mM Cu2+ reveals that vigorously affected the Vigna unguiculata (L) (cow pea) plants and The green algae Ulva lactuca is effectively biosorbed the copper heavy metal and get rid from soil pollution and improve crop yield.
