Cell Differentiation

Front

_________ _________ are a special type of body cell that can develop into different types of cells.

Back

stem cells

Answer explanation

Stem cells are unique body cells capable of developing into various cell types, making them essential for growth, repair, and regeneration in organisms.

Front

The process by which cells that are not specialized develop into their specialized form.

Back

cell differentiation

Answer explanation

Cell differentiation is the process by which unspecialized cells develop into specialized forms, allowing them to perform specific functions in the body.

Front

Stem cells are cells that...

Back

are undifferentiated

Answer explanation

Stem cells are undifferentiated cells, meaning they have not yet developed into specific cell types. This characteristic allows them to divide and potentially develop into various specialized cells, unlike the other options.

Front

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

Back

differentiation

Answer explanation

Differentiation is the process by which a fertilized egg develops into various cell types, such as muscle and nerve cells, by activating specific genes while others remain inactive, allowing for specialized functions.

Front

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

Back

Embryonic stem cells can differentiate into more cell types than adult stem cells

Answer explanation

Embryonic stem cells are pluripotent, meaning they can differentiate into any cell type in the body, while adult stem cells are typically multipotent, limiting their differentiation potential to a narrower range of cell types.

Front

There are about 200 cells in the human body. All these cells have the same DNA. True or False?

Back

True

Answer explanation

True. All cells in the human body contain the same DNA, which is crucial for maintaining the organism's identity and function, despite the cells differentiating into various types.

Front

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

Back

stem cells

Answer explanation

Stem cells are unspecialized cells that can differentiate into various cell types, unlike specialized or differentiated cells which have specific functions. Therefore, the correct answer is stem cells.

Front

_____________ ______________ is the process by which cells that are not specialized develop into their specialized form.

Back

cell differentiation

Answer explanation

Cell differentiation is the process by which unspecialized cells develop into specialized forms, allowing them to perform specific functions in the body. This is essential for the development and maintenance of multicellular organisms.

Front

Which of the following best describes stem cells?

Back

Original human cells that are able to develop into specialized cells

Answer explanation

Stem cells are original human cells that can develop into specialized cells, unlike differentiated cells, which have already taken on specific functions. They retain the ability to divide and differentiate into various cell types.

Front

During the process of differentiation, what happens to DNA?

Back

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

Answer explanation

During differentiation, only specific sections of DNA are activated, allowing cells to develop unique structures and functions. This selective activation is crucial for the specialization of body cells.
