WebOnly the single-celled organisms of the domains Bacteria and Archaea are classified as prokaryotes— pro means before and kary means nucleus. Animals, plants, fungi, and protists are all eukaryotes— eu means true—and are made up of eukaryotic cells. Often, though—as in the case of we humans—there are some prokaryotic friends hanging around. rodan and fields mascaraWebAlexa Jacob. The Endoplasmic Reticulum in a eukaryotic cell is the transport network of the cell and it extends from and connects the nuclear membrane to the plasma membrane of a cell. But then whenever we draw a diagram of a typical plant or animal cell, we never extend it to the plasma membrane- we always leave it somewhere in the cytoplasm. o\u0027reilly auto parts aubrey txWebEndosymbiosis and the Evolution of Eukaryotes. ...
