Front

What is cell differentiation?

Back

Process by which cells become specialized.

Front

What are stem cells?

Back

Undifferentiated cells that can become any type of cell.

Front

What is one goal of cellular differentiation/specialization?

Back

To create specialized cells to help the organism maintain homeostasis.

Front

What does 'pluripotent' mean?

Back

Able to divide and make many different types of cells.

Front

What is the importance of apoptosis?

Back

To eliminate damaged or unnecessary cells.

Front

What are specialized cells?

Back

Cells that have specific functions and structures tailored to their roles.

Front

What is the role of stem cells in development?

Back

They can differentiate into various cell types needed for growth and repair.

Front

What is the difference between totipotent and pluripotent stem cells?

Back

Totipotent stem cells can become any cell type, including placental cells; pluripotent can become any cell type except placental.

Front

What triggers cell differentiation?

Back

Signals from the environment, including chemical signals and gene expression.

Front

What is the process of apoptosis?

Back

A programmed cell death process that removes unnecessary or damaged cells.
