Stem Cell vs. Specialized Cell Notes

What is the function of specialized cells?

• They can grow into any type of cell.

• They carry out specific functions within the body.

• They contain a partial set of DNA.

• They are found mainly in 4-5 day old embryos.

What is cell differentiation?

• The specialization of cells occurring during an organism's development.

• The process by which a cell becomes a stem cell.

• The division of a cell into multiple copies of itself.

• The replication of DNA within a cell.

Which of the following is a characteristic of stem cells?

• They can only make more of the same specialized cells.

• They only contain certain genes that are expressed.

• They are unipotent.

• They have the potential to become any kind of cell.

What does pluripotent mean?

• Cannot develop into any cell type.

• Can develop into many different cell types.

• Can develop into one cell type.

• Can only replicate into the same type of cell.

How do stem cells differ from specialized cells?

• Stem cells can only make more of the same specialized cells.

• Stem cells are found only in adults.

• Stem cells contain a partial set of DNA.

• Stem cells are unspecialized and have the potential to become any kind of cell.

What role do growth factors play in the development of stem cells?

• They influence gene expression to determine the type of cell it will become.

• They replicate DNA within stem cells.

• They ensure stem cells remain pluripotent.

• They decrease the potential of stem cells.

What is gene regulation?

• The process by which cells become pluripotent.

• The replication of genes within a cell.

• The turning on and off of genes within a cell in response to environmental stimuli or other factors.

• The division of a gene into multiple copies.
