CHAPTER 5.5 Multicellular Life

Interactions All multicellular organisms are made of different kinds of cells. All types of cells need to fit and work together. Tissue – group of cells that work together to perform a specific function.

Groupings Organs – groups of tissues that work together to perform a specific function. When organs work together they form organ systems. All of these parts work to maintain homeostasis.

Differentiation Early cells must specialize in order to form different kinds of cells. This is called cell differentiation. A cell can change it’s whole function based on where it is. That means cells can change how they function.

Stem Cells Stem cells can do one of three things:  Divide and renew themselves for a long time.  Remain undifferentiated (unspecialized)  Develop into a wide range of specialized cells. Two kids of stem cells:  Adult Stem Cells  Embryonic Stem Cells

Stem cells Adult stem cells can be found all over the body. This is good for a specific purpose.  Depending of what kinds of cells they are, they can only become that kind of cell again. Embryonic stem cells that are formed during an embryo’s first 3-5 days.  These can develop into any kind of cell in the body.
