Cell Differentiation - Mastery Ticket

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

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

This type of cell sends messages throughout the body in the form of electrical impulse.

• nerve cell
• sperm cell
• muscle cell
• skin cell

Which best explains why muscle cells are different from blood cells?

• Muscle cells are produced by the brain, but blood cells are produced by the heart. 
• Different genes are activated in muscle cells than in blood cells. 
• Muscles cells experience different environmental influences than blood cells. 
• A mutation occurs during the development of muscle cells but not in blood cells.
