Mitosis 2

Cancer cells form masses of cells called

• p53

• growth factors

• tumors

• cyclins

Cancer is a disorder in which some cells have lost the ability to control their

• spindle fibers

• surface area

• size

• growth rate

What is cell differentiation?

• Process by which cells produce more cells
• Process by which cells become specialized
• Process by which cells become unspecialized
• Process by which cells die

What is one goal of cellular differentiation/specialization?

• To create specialized cells to help organism maintain homeostasis.
• To many cells.
• To make stem cells
• to make single celled organisms

Stem cells are

• cells that grow uncontrollably
• undifferentiated and can be any type of cell
• never go through cell division
• only found in embryos

what is the role of stem cells in the body 

• fight against infection 
• provide specialized roles in the body 
• used for fertility treatment 
• they produce new specialized cells in the body to replace old cells that are used up 

Name the cellular process responsible for repair, growth, and development in living organisms.

• meiosis

• mitosis

• transcription

• translation

Stem cell research is controversial because in involves?

• social issues
• ethical issues
• educational issues
• economical issues

What is the difference between embryonic stem cells and adult stem cells?

• Embryonic stem cells can differentiate into more cell types than adult stem cells
• Adult stem cells are pluripotent, just like embryonic stem cells
• Adult stem cells can differentiate into more cell types than embryonic stem cells
• Adult stem cells grow bigger than embryonic stem cells

What is the importance of apoptosis?

• To eliminate damaged or unnecessary cells
• To create specialized cells
• To produce two identical cells
• To cause uncontrolled cell growth
