11.4 Cell Differentiation

Front

What does 'pluripotent' mean?

Back

Pluripotent refers to the ability of a cell to divide and differentiate into many different types of cells.

Front

What is the primary goal of cellular differentiation?

Back

The primary goal of cellular differentiation is to create specialized cells that help the organism maintain homeostasis.

Front

Define cell differentiation.

Back

Cell differentiation is the process by which a less specialized cell becomes a more specialized cell.

Front

Why are muscle cells different from blood cells?

Back

Muscle cells and blood cells are different because different genes are activated in each type of cell.

Front

What is the role of stem cells in differentiation?

Back

Stem cells are undifferentiated cells that have the potential to become various types of specialized cells.

Front

What is the difference between totipotent and pluripotent cells?

Back

Totipotent cells can develop into any cell type, including extra-embryonic tissues, while pluripotent cells can develop into almost any cell type but not extra-embryonic tissues.

Front

What is the significance of gene expression in cell differentiation?

Back

Gene expression determines which proteins are produced in a cell, influencing its structure and function, and thus its specialization.

Front

How does the environment influence cell differentiation?

Back

The environment can influence cell differentiation through signals such as growth factors, which can activate specific genes.

Front

What is the process by which stem cells become specialized cells called?

Back

The process by which stem cells become specialized cells is called differentiation.

Front

What are some examples of specialized cells in the human body?

Back

Examples of specialized cells include muscle cells, nerve cells, and blood cells.
