Exploring Cell Division Concepts

What is the primary difference between meiosis and mitosis?

• Meiosis occurs in all body cells, while mitosis occurs only in reproductive cells.

• Meiosis involves one division, while mitosis involves two divisions.

• Meiosis creates gametes with half the number of chromosomes, while mitosis creates identical cells.

• Meiosis creates identical cells, while mitosis creates different cells.

What is the first step in both meiosis and mitosis?

• Crossing over

• Chromosome alignment

• Replication

• Nuclear membrane disintegration

During meiosis, what process involves the exchange of genetic information between chromosomes?

• Replication

• Crossing over

• Spindle fiber formation

• Nuclear membrane reformation

How many daughter cells are produced at the end of meiosis?

• Three

• Five

• Two

• Four

What happens to the nuclear membrane during the initial stages of meiosis?

• It remains unchanged

• It disintegrates

• It duplicates

• It thickens

What is the result of crossing over and random assortment in meiosis?

• Daughter cells with no DNA

• Daughter cells with the same DNA as the parent

• Daughter cells with half the DNA of the parent

• Identical daughter cells

What are gametes?

• Cells with double the DNA of the parent

• Identical cells to the parent

• Sperm and egg cells with half the DNA of the parent

• Cells with no DNA

How many chromosomes do human gametes have?

• 69

• 46

• 23

• 92

In females, how many eggs are produced from one meiotic cell division?

• One

• Two

• Four

• Three

In males, how many sperm cells are produced from one meiotic cell division?

• Four

• One

• Two

• Three
