Cells carry on the many functions needed to sustain life. Specialized cells perform specialized functions in multicellular organisms. Groups of specialized cells cooperate to form a tissue, such as a muscle. Different tissues are in turn grouped together to form larger functional units, called organs.

Multicellular organisms are organisms that are made up of more than one type of cell and have specialized cells that are grouped together to carry out specialized functions.

advantages of that organization? Cells are organized into tissues in multicellular organisms. Tissues are further organized into organs. This organization allows for the localization and isolation of biological processes.

The cells of multicellular organisms become specialized for particular tasks and communicate with one another. Use eukaryote, prokaryote, and membrane-bound organelles in a meaningful sentence.

Why do multicellular organisms contain specialized cells? To more efficiently perform wide variety of physiological and biochemical functions. A unicellular organism cannot specialize to the degree as all the functions and needs of the organism must be made by one cell. Multicellular enables a cell to become large.

Unicellular organisms are made up of only one cell that carries out all of the functions needed by the organism, while multicellular organisms use many different cells to function. Unicellular organisms include bacteria, protists, and yeast.

Bacteria reproduce by binary fission. In this process the bacterium, which is a single cell, divides into two identical daughter cells.

It is not a membrane bound nucleus, but simply an area of the cytoplasm where the strands of DNA are found. Most bacteria have a single, circular chromosome that is responsible for replication, although a few species do have two or more.
