Cell Specialization

What happens to the DNA of a cell during differentiation?

• All sections of DNA are activated equally.

• Only specific sections of DNA are activated, while others remain inactive.

• The DNA is completely destroyed during differentiation.

• The DNA remains unchanged throughout the process.

How do cells differentiate to perform different functions?

• Cells differentiate by turning on or off different genes inside that cell.

• Cells differentiate by changing their shape and size only.

• Cells differentiate by absorbing nutrients from their environment.

• Cells differentiate by replicating their DNA multiple times.

What is the outcome of improper cell differentiation?

• Cells grow uncontrollably, leading to diseases such as cancer.

• Cells become more specialized and function properly.

• Cells die off at a faster rate than normal.

• Cells remain in a dormant state without any growth.

What is the significance of stem cells in development?

• Stem cells are crucial for growth, development, and repair of tissues because they can differentiate into various cell types.

• Stem cells are primarily involved in the production of hormones in the body.

• Stem cells are only found in embryos and have no role in adult tissue.

• Stem cells are responsible for the formation of bones and muscles exclusively.

What is the difference between stem cells and differentiated cells?

• Stem cells are fully developed cells with specific functions.

• Differentiated cells can become any cell type.

• Stem cells are undifferentiated and can become any cell type, while differentiated cells have specific functions and structures.

• Differentiated cells are the building blocks of stem cells.

What are stem cells?

• Stem cells are specialized cells that perform specific functions in the body.

• Stem cells are undifferentiated cells that have the potential to become any type of cell in the body.

• Stem cells are cells that have already differentiated into specific cell types.

• Stem cells are cells that only exist in embryos and cannot be found in adults.

What is the importance of gene regulation in cell specialization?

• Gene regulation allows cells to specialize and perform their functions by ensuring the right genes are expressed at the right times.

• Gene regulation is unimportant in cell specialization and has no effect on cell functions.

• Gene regulation only affects the physical structure of cells, not their functions.

• Gene regulation is a process that occurs only in prokaryotic cells, not in eukaryotic cells.

True or False: All cells in the human body have the same DNA.

• True

• False

• Only in certain cells

• Only in stem cells

Can differentiated cells revert back to stem cells?

• Yes, they can revert back naturally.

• Generally, differentiated cells cannot revert back to stem cells, although some techniques in research aim to induce this.

• Yes, with the right conditions they can revert.

• Only in certain organisms can they revert.

What is the role of DNA in cell differentiation?

• DNA is responsible for the replication of cells.

• DNA carries the genetic information necessary for protein synthesis.

• During differentiation, only specific sections of DNA are activated to determine the structure and functions of a body cell.

• DNA is involved in the transport of nutrients within the cell.
