Bio Review Quiz

Specialized cells such as muscle, blood, or nerve cells are caused by cell differentiation, which is led by:

• DNA

• nucleus

• ribosomes

• plasma membrane

Cells in our body that send messages back and forth are called:

• Muscle cells

• Nerve cells

• Organelles

• DNA

What causes the cells in our bodies to perform different functions?

• DNA

• nucleus

• ribosomes

• plasma membrane

Cells differentiate to perform different functions because:

• All genes are turned on inside that cell.

• All genes are turned off inside that cell.

• Different genes are turned on inside that cell.

• Different genes are turned on or off inside that cell.

During the process of differentiation,

• All sections of DNA are activated to determine the structure of a body cell.

• Only one section of DNA is deactivated to determine the structure of a body cell.

• Only specific sections of DNA sequence are activated to determine the structure and functions of a body cell.

Unspecialized cells in our body that have the ability to differentiate into different types of cells are called:

• Specialized cells

• Differentiated cells

• Nerve cells

• Stem cells

What process best explains how muscle cells and nerve cells can develop from the same fertilized egg?

• Genetic engineering

• Survival of the fittest

• Differentiation

• Selective breeding

What is the purpose of Mitosis?

• Growth of an organism and repair of damaged tissue

• To help the body get rid of extra cells

• To increase the amount of classwork you have to do

• To get rid of the nucleus

How many daughter cells are produced in mitosis?

• 1

• 2

• 4

• 6

Bone cells are different from brain cells because bone cells –

• do not undergo cell division

• cannot maintain homeostasis

• contain charged ions

• express different genes
