cell differentiation

The name for undifferentiated cells is

• root cells

• stem cells

• leaf cells

Stem cells that come from a recently fertilized egg are

• embryonic

• adult

When a cell has gone through the process of specializing for a role (job) it is

• stem

• differentiated

• non-specific

Adult stem cells are found in

• embryos

• skin

• bone marrow

When we say genes are regulated, it means they are

• on the x chromosome

• turned on or off

• mutated

In embryonic development,  the process by which cells specialize is called

• differentiation
• morphogenesis
• cell division
• endoplasmic reticulum

Stem cells are:

• specialized cells with specific functions in the body

• cells that are undifferentiated and can differentiate into any cell type

• reproductive cells

• cells that can only do one job

In what way is the DNA of a nerve cell different from the DNA of a muscle cell?

• The DNA is the same but each cell contains different genes
• The DNA is the same but different genes are turned on and turned off in each cell
• The DNA is different, but the same genes are turned on and off in each cell
• The DNA is different, but each cell contains the same genes

What makes a muscle cells different from a nerve cell?

• They have different DNA to make them those specialized cell types.

• They have different portions of activated DNA.

• They experience different environmental influences.

• They have different genes.

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
