Which of the following is NOT a stage of mitosis?
Cytokinesis
Telophase
Prophase
Metaphase
What happens to cells after mitosis?
They fuse with other cells
They become identical to the parent cell
They die
They may undergo differentiation
How does cell differentiation occur?
Through random mutations
Through changes in gene expression and environmental signals
By losing genetic material
By merging with other cells
What can result from abnormal cell division?
Improved cell function
Increased energy production
Faster healing
Cancer
What role do stem cells play in an organism?
They are cells that only produce energy
They are cells that cannot divide
They are undifferentiated cells with the potential to become various specialized cell types
They are specialized cells with a single function
How can models help in understanding mitosis and differentiation?
By eliminating the need for experiments
By illustrating the processes through diagrams and simulations
By providing real-life examples
By simplifying the genetic code
What is the significance of studying abnormal cell division?
To understand diseases like cancer
To increase cell division speed
To create new cell types
To eliminate the need for mitosis
How does stem cell research benefit medical science?
By reducing the need for surgery
By exploring the potential of stem cells to treat diseases
By increasing the lifespan of cells
By making cells immune to diseases
Which of the following is an example of a specialized cell resulting from differentiation?
Virus
Stem cell
Muscle cell
Bacterial cell
Why is it important to understand the outcomes of mitotic division and differentiation?
To eliminate genetic disorders
To create new species
To stop cell division
To comprehend how organisms grow and develop
What is the main function of mitosis in multicellular organisms?
To destroy old cells
To produce energy
To create new organisms
To facilitate growth, repair, and replacement of cells
Which process allows cells to perform specific roles in an organism?
Respiration
Photosynthesis
Differentiation
Mitosis
What is a potential consequence of uncontrolled cell division?
Improved tissue function
Enhanced immune response
Cancer
Increased genetic diversity
What guides cell differentiation?
Random chance
Cell size
Gene expression and environmental signals
Nutrient availability
What is the role of stem cells in tissue repair?
They only function in embryos
They prevent tissue damage
They differentiate into specific cell types needed for repair
They are unable to repair tissues
