Cell Differentiation Review #2

Front

What is mitosis?

Back

Mitosis is the process of cell division that results in two daughter cells, each having the same number of chromosomes as the parent cell.

What is the diploid number of chromosomes in human skin cells?

Back

The diploid number of chromosomes in human skin cells is 46.

Front

What distinguishes stem cells from other body cells?

Back

Stem cells are unspecialized cells that can differentiate into various cell types.

Front

How does gene expression relate to cell differentiation?

Back

Cell differentiation occurs when genes are turned on and off at various times, leading to the production of specific proteins that define cell function.

Front

Why do heart cells and liver cells have different functions despite having the same DNA?

Back

Heart cells and liver cells express different genes, which leads to the production of different proteins and functions.

Front

What is the role of stem cells in development?

Back

Stem cells play a crucial role in development by differentiating into various specialized cell types needed for forming tissues and organs.

Front

What is the significance of the cell cycle in mitosis?

Back

The cell cycle is essential for mitosis as it includes phases that prepare the cell for division, ensuring accurate replication and distribution of chromosomes.

Front

What are the phases of mitosis?

Back

The phases of mitosis include prophase, metaphase, anaphase, and telophase.

Front

What is the outcome of mitosis?

Back

The outcome of mitosis is the formation of two genetically identical daughter cells.

Front

How do environmental factors influence cell differentiation?

Back

Environmental factors can influence cell differentiation by affecting gene expression and signaling pathways that determine cell fate.
