B.5(B) Quiz 1 Cell Differentiation

The diagram shows a process that occurs during the development of an organism. Which statement explains how the different cell types in the image are formed?

• Each cell type uses its own unique replication process.

• Each cell type expresses different genes at different times.

• Each cell type contains a different part of the original DNA.

• Each cell type has different enzymes to replicate genetic material.

A ​​ (a)   cell is a cell that is not specialized and can become any type of specialized cell. When a stem cell divides, it produces two daughter cells. One daughter cell will remain a stem cell, while the other daughter cell will

differentiate into a ​ (b)   cell. The factor that will determine what type of specialized cell is produced is the​ (c)  

• stem
• specialized
• genes that are expressed.
• gamete
• cancer
• haploid
• mutated
• size of the cell
• number of the chromosomes that are replicated
• length of the cell cycle

The following diagram shows the cell differentiation process that occurs to create various types of cells. Correctly label the diagram with the names of the cells and what process occurs in between,

f

g

mutations occur

mitosis occurs

Mutated cell

Stem cell

haploid cell

gametic cell

Specialized cell

crossing over occurs

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.
