What is Apoptosis?

• A tumor

• A protein

• Programmed cell death

• Cell cycle checkpoints

What is cell differentiation?

• The process where unspecialized cells become different in structure and function.

• When DNA controls the cell cycle.

• The ability of cells to make more cells.

• The ability of cells to maintain homeostasis.

Which is true about Embryonic Stem Cells.

• They no longer do mitosis, their cell type is set and can not change
• They are limited to the type of cell they can become
• They can become any cell type in the body
• They are found in adults

Cells that have the ability to become any type of specialized cell in the body are called:

• cell membranes

• stem cells

• nerve cells

• cardiac cells

The diagram shows the process of cell specialization from a single stem cell. Which of the following statements is true about the process of specialization.

• Specilized cells (blood, skin, nervous etc) cannot be produced from a single stem cell
• Specilized cells are produced immediately following fertilization
• Even though all the cells in an organism come from one single cell, they can specialize into different cell types
• Sincce all the cells in an organism come from one single cell, they must all have the same structure and function

What is one goal of cellular differentiation/specialization?

• To create specialized cells to help organism maintain homeostasis.
• To many cells.
• To make stem cells
• to make single celled organisms

BEFORE mitosis can occur, the cell must complete which of the following?

• genetic mutations
• DNA replication
• photosynthesis
• cell differentiation

Compared to the parent cell after mitosis, daughter cells are - 

• differentiated
• more motile
• less specialized
• genetically identical

Nerve cells are different than muscle cells because muscle cells - 

• cannot receive chemical signals
• express a different set of genes
• do not undergo mitotic divisions
• require less cellular energy
