Stem cells are

cells that grow uncontrollably

undifferentiated and can be any type of cell

never go through cell division

only found in embryos

Stem cells can be obtained from

embryos

some adult tissues

umbilical cord blood

all of the above

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.

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

Which is true about embryonic stem cells?

They no longer divide, their cell type is set and cannot change.

They can develop into only one type of cell.

They can become any cell type in the body.

They are found in adults.

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 cell research is controversial because in involves?

social issues

ethical issues

educational issues

economical issues

The skin cell and hair cell contain different sets of DNA. And that is why they are different cells.

True

False

10.

Nerve cells have different DNA from hair and skin cells in your body.

True

False

11.

Specialized cells such as skin cell and muscle cell carry out specific function because only certain parts of genes are expressed.

True

False

12.

Hair cell and nerve cell have identical DNA. The DNA is changed in skin cell to perform a specific function such as protection.

True

False

13.

At the end of cell specialization, will all cells have the same structure?

Yes

14.

True or False. All cells contain all of our DNA.

True

False

15.

The process of a cell developing into a certain type has two names, what are they?

Replication

Translation

Differentiation

Specialization

16.

During development, an embryo is exposed to extreme heat. Will this affect how it develops?

Yes

17.

What can stem cells be used for?

Repairing damage from a heart attack

Regrowing limbs

Bone marrow transplants

All of these

18.

Cell differentiation is critical during embryonic development. The process of cell differentiation results in the production of many different kinds of specialized cells. This process is most directly influenced by

DNA

Lipids

Carbohydrates

ATP

19.

As a fertilized egg divides, the cells differentiate because they

have different sets of DNA passed on to the daughter cells

have different sets of genes activated in the daughter cells

have mutations that cause different genes to appear in the daughter cells

randomly assort the chromosomes into different daughter cells

20.

Which are external factors that can regulate gene expression?

Operons

Homeobox Genes

Transcription Factors

Temperature

100 %
