Let"s Get Started What is Cell Differentiation? Roles of DNA and RNA in Cell Differentiation Environmental Factors Influence Gene Expression Specialized Plant Cells Specialized Animal Cells Journal Activity

Let’s discover a basic characteristic of multicellular organisms—cell differentiation and also field of expertise. Before you get began, don’t forgain to print out your OnTRACK Biology Journal.

You are watching: Why do complex organisms need specialized cells

Living organisms deserve to be made of a single cell, such as bacteria and protists, or they can be multicellular, choose plants, animals, and also fungi. Unicellular organisms, favor bacteria, are able to percreate all life features within one single cell. They have the right to move molecules, metabolize nutrients, and redevelop within this one cell.

Multicellular organisms need many kind of various types of cells to lug out the exact same life processes. Each of these special types of cells has a different structure that helps it perdevelop a specific attribute. Humans have actually many kind of various forms of cells with different jobs, such as blood cells that bring oxygen and also nerve cells that transmit signals to all components of the body. Cell differentiation is the procedure through which cells come to be specialized in order to perdevelop various features.


Specialized Cells in the Human being Body



Multicellular organisms start as simply one single cell—a fertilized egg. Growing from one single cell to trillions of specialized cells that perform various functions is a procedure that happens through the regulation of DNA and also RNA.
