Hello my dear friend,we know the fact that An ion is an atom or molecule  in which the total number of electrons  is not equal to the total number of protons, giving it a net positive or negative electrical charge. An anion (pronounced /?æn.a?.?n/ AN-eye-?n), from the Greek word ??? (an?), meaning "up", is an ion with more electrons than protons, giving it a net negative charge (since electrons are negatively charged and protons are positively charged). Conversely, a cation (pronounced /?kæt.a?.?n/ KAT-eye-?n), from the Greek word ???? (kata), meaning "down", is an ion with more protons than electrons, giving it a positive charge.Furthermore,The nucleus is a highly specialized organelle that serves as the information processing and administrative center of the cell. This organelle has two major functions: it stores the cell's hereditary material, or DNA, and it coordinates the cell's activities, which include growth, intermediary metabolism, protein synthesis, and reproduction (cell division).Thank you and God Bless!!!!!!!!!
