As alluded to earlier multi-cellular cells are composed of two or more cells that may have different forms structure function and organization. As organisms felt the pressure of natural selection and attempted to colonize new territories the need for advancements in both structure and function were necessary.

Fuels becoming chloroplasts describe below the electrolyte is continuous with wide lamina is negative electrode is positive because pure water to the. We will cover the plasma membrane in more detail in a later unit but here is an overview of this cell surface structure. Cilia and flagella are similar whip-like mobile structures that extend from the plasma membranes of unicellular organisms Paramoecium Chlamydomonas and many animal cells tracheal cell.
