Question

how is cell differentiation different than mitosis?

cell differentiation does not cause proliferation

cell differentiation produces cells with different gene expressions

cell differentiation produces cells with different gene expressions

cell differentiation only occurs after a wound

Answer 1

Cell differentiation and mitosis are distinct processes in cell biology, each playing a unique role in the life cycle of cells.

1. **Mitosis**: This is the process of cell division that results in two genetically identical daughter cells from a single parent cell. It is primarily a method of proliferation, allowing for growth, tissue repair, and asexual reproduction in some organisms. During mitosis, the duplicated chromosomes are evenly distributed to the daughter cells, maintaining identical genetic information.

2. **Cell Differentiation**: This process involves the transformation of a relatively unspecialized or stem cell into a specialized cell type with specific functions. This involves changes in gene expression where certain genes are activated or suppressed, leading to the development of distinct physical and functional characteristics of the cell. For example, a stem cell may differentiate into a muscle cell, a neuron, or a blood cell, each with unique functions and properties.

Now let's relate this to the options you've provided:

- **Cell differentiation does not cause proliferation**: This is generally true. Differentiation refers mainly to the process where cells become specialized and may not necessarily lead to an increase in the number of cells.

- **Cell differentiation produces cells with different gene expressions**: This is correct. During differentiation, the cells express different sets of genes, leading to different functions and characteristics.

- The third option is a repetition of the second one.

- **Cell differentiation only occurs after a wound**: This statement is not accurate. While differentiation can occur as part of the healing process in response to a wound, it also happens during normal development and growth in an organism, not just in response to injury.

In summary, the key difference is that cell differentiation produces cells with distinct gene expressions and functions, while mitosis is about cell division and proliferation without necessarily changing the cell's identity.
