Hi,
I read a research paper on "Heavy Metal Bioaccumulation and Toxicity with Special Reference to Microalgae". It looks like Metal
ions are adsorbed first to the surface of cells by the interactions between the metal ions and metal-functional groups such as carboxyl, phosphate, hydroxyl, amino,sulphur, sulphide, thiol, etc., present in the cell wall and then they penetrate the cell membrane and enter the cells.
