Meiose/Mitose

Question 1

What is mitosis?

Answer 1

Mitosis is the process of cell division that results in two genetically identical daughter cells from a single parent cell.

Question 2

True or False: Mitosis results in four daughter cells.

Answer 2

False

Question 3

What is the primary purpose of meiosis?

Answer 3

The primary purpose of meiosis is to produce gametes (sperm and eggs) for sexual reproduction.

Question 4

Fill in the blank: Meiosis consists of two consecutive divisions called _____ and _____.

Answer 4

meiosis I; meiosis II

Question 5

During which phase of mitosis do the chromosomes align at the cell’s equator?

Answer 5

Metaphase

Question 6

What is the difference between mitosis and meiosis in terms of the number of daughter cells produced?

Answer 6

Mitosis produces two daughter cells, while meiosis produces four daughter cells.

Question 7

True or False: Crossing over occurs during mitosis.

Answer 7

False

Question 8

In which stage of meiosis does crossing over occur?

Answer 8

Prophase I

Question 9

What are homologous chromosomes?

Answer 9

Homologous chromosomes are pairs of chromosomes that have the same structure and gene sequence, one inherited from each parent.

Question 10

What is the significance of meiosis in genetic diversity?

Answer 10

Meiosis increases genetic diversity through processes such as crossing over and independent assortment.

Question 11

During which phase of mitosis does the nuclear envelope reform?

Answer 11

Telophase

Question 12

Fill in the blank: The phase where cells spend most of their time is called _____ phase.

Answer 12

interphase

Question 13

What is the term for the physical division of the cytoplasm during cell division?

Answer 13

Cytokinesis

Question 14

True or False: Meiosis results in genetically identical cells.

Answer 14

False

Question 15

What is the term for the first division in meiosis?

Answer 15

Meiosis I

Question 16

In which stage of mitosis do sister chromatids separate?

Answer 16

Anaphase

Question 17

What is a key feature of prophase I in meiosis?

Answer 17

Homologous chromosomes pair up and crossing over occurs.

Question 18

Fill in the blank: The two main types of cell division are _____ and _____.

Answer 18

mitosis; meiosis

Question 19

What happens during metaphase II of meiosis?

Answer 19

Chromosomes align at the equatorial plane of the cell.

Question 20

True or False: Each daughter cell from meiosis contains the same number of chromosomes as the parent cell.

Answer 20

False

Question 21

What is the end result of meiosis II?

Answer 21

Four haploid daughter cells.

Question 22

What process occurs during anaphase I of meiosis?

Answer 22

Homologous chromosomes are pulled apart to opposite poles.

Question 23

During which phase of cell division does DNA replication occur?

Answer 23

Interphase

Question 24

What is the term for cells that result from fertilization?

Answer 24

Zygotes

Question 25

Fill in the blank: The two major phases of the cell cycle are _____ and _____.

Answer 25

interphase; mitotic phase

Question 26

What is the role of spindle fibers during mitosis?

Answer 26

Spindle fibers help separate and pull chromosomes to opposite ends of the cell.

Question 27

True or False: Meiosis includes only one round of DNA replication.

Answer 27

True
