Yes, all organisms begin as a single-celled zygote. Then they undergo meiosis and mitosis to replicate if they are multicellular or stay the same if they are single celled organisms.
Plankton and phytoplankton.
multicellular organisms begin as a single cell.
Living things begin with cells, which are the basic units of life. All organisms, from single-celled bacteria to complex multicellular organisms like plants and animals, are made up of one or more cells. These cells contain genetic material and are capable of carrying out essential life processes, such as metabolism, growth, and reproduction. Thus, the cell is fundamental to the structure and function of all living things.
