Ch 17.3 and 17.4

What is the role of a growth factor in cell biology?

• It is a protein that regulates the cell cycle.

• It is a process of programmed cell death.

• It is an external growth regulatory protein that stimulates the growth and division of cells.

• It is a mass of rapidly dividing cells that can damage surrounding tissue.

What does totipotent mean in terms of cell potential?

• Cells that are capable of developing into most but not all of the body’s cells.

• Cells that are able to develop into any type of cell in the body, cells only found in a zygote.

• Cells with limited potential to develop into many types of differentiated cells.

• Unspecialized cells that can give rise to one or more types of specialized cell.

• A protein that regulates the cell cycle.

• An early stage of development in mammals. It is a hollow ball of cells.

• A process of programmed cell death.

• A mass of rapidly dividing cells that can damage surrounding tissue.

What does pluripotent mean in terms of cell potential?

• Cells that are able to develop into any type of cell in the body.

• Cells that are capable of developing into most but not all of the body’s cells, cells found inside blastocyst.

• Cells with limited potential to develop into many types of differentiated cells.

• Unspecialized cells that can give rise to one or more types of specialized cell.
