Les 4: Cell Division

What are four functions of cell division?

• Repairing tissues, growth, reproduction, and producing new structures

• Digestion, respiration, circulation, and excretion

• Synthesizing proteins, generating energy, cell movement, and cell communication

• Producing hormones, detoxification, storage of nutrients, and waste elimination

What happens when a strawberry plant grows new stems and roots through cell division?

• The new stems and roots become part of the original plant.

• The new stems and roots die off quickly.

• The new stems and roots break away from the parent plant and become a separate plant.

• The new stems and roots merge with other plants to form hybrids.

How does cell division contribute to healing after an injury?

• It slows down the healing process by reducing the number of cells.

• It replaces damaged cells with identical copies.

• It increases the risk of infection at the injury site.

• It produces new cells to repair tissues and clean up the damaged area.

What happens to a cell's genetic information during the cell cycle?

• It is discarded and replaced with new genetic information.

• It remains unchanged throughout the cycle.

• It is duplicated so each daughter cell has the same genetic information.

• It is randomly altered to create genetic diversity.

What is the name of the phase where the cell's cytoplasm physically divides into two?

• Interphase

• Mitosis

• Cytokinesis

• Metaphase

Which phase is described as the cell growing in size and doubling its contents?

• Interphase

• Prophase

• Anaphase

• Telophase

What is the sequence of events in which the cell grows, prepares for division, and divides to form two daughter cells known as?

• Cell division

• Cell enlargement

• Cell cycle

• Cell replication

During which phase do the two daughter cells have roughly equal contents?

• Interphase

• Prophase

• Anaphase

• Mitosis

How does the number of cells increase with each new division of the cells?

• The number of cells remains the same.

• The number of cells doubles.

• The number of cells triples.

• The number of cells decreases.

How many cells would there be after five divisions?

• 16 cells

• 32 cells

• 64 cells

• 128 cells
