Structural Hierarchy in Animals

Cell Differentiation The process by which a cell becomes specialized to perform a specific function. Directed by genetic information inside the cell An undifferentiated Cell is called a stem cell

Cell Differentiation Stem Cells Cells which can develop into different types of cells depending on which parts of DNA are switched on.

Stem Cells

Stem Cells Embryonic Stem Cells can differentiate into any kind of cell. Tissue Stem Cells only able to differentiate into certain types of cells.

Levels of Organization or Hierarchy in Animals Building An Organism! Levels of Organization or Hierarchy in Animals Forms a pyramid with the most complex structure at the top, and least complex at the bottom

Organism Organ System Organ Tissue Cell

Tissues – a group of specialized cells which provide a specific function ex. Epithelial tissue, connective tissue, muscle tissue or nerve tissue

Organs – a group of specialized tissues working together to perform a specific function ex. Stomach, heart, lungs or muscles

Organ Systems – a system of one or more organs/structures that work together to perform a major vital body function ex. Obtain and distribute oxygen and nutrients

Pulling It All Together

Thinking/Inquiry Question Explain how 3 organ systems work together to enable you to be mobile and active.
