What is cell differentiation?

• Process by which cells produce MORE cells.

• Process by which cells become UNSPECIALIZED

• Process by with cells become SPECIALIZED

• Process by which cells become old and DIE

What is one goal of cellular differentiation?

• To create many identical copies of cells.

• To make stem cells for use in the future.

• To make single-celled organisms.

• To make specialized cells to maintain homeostasis.

What is the purpose of some organisms having different specialized cell types each doing particular jobs?

• if all the cells were the same they would fight each other

• it is impossible for a single cell to do everything needed to keep it alive

• in multicellular organisms specialized cells work together to perform life functions

• this is not true - all cells are the same and do the same jobs
