Biology Chapter 5 : Topic 3
Comparison of Mitosis and Meiosis
1 / 15
What is the main difference between mitosis and meiosis?
Reasoning: Mitosis produces genetically identical daughter cells, while meiosis produces genetically varied cells.
2 / 15
How many daughter cells are produced from one parent cell after mitosis?
Reasoning: One mitotic division produces two daughter cells.
3 / 15
How many daughter cells are produced after meiosis?
Reasoning: Meiosis produces four daughter cells.
4 / 15
Which process maintains the chromosome number of the parent cell?
Reasoning: Mitosis produces cells with the same chromosome number as the parent.
5 / 15
Which process reduces the chromosome number by half?
Reasoning: Meiosis is a reduction division.
6 / 15
Which process is responsible for growth in multicellular organisms?
Reasoning: Growth occurs through repeated mitotic divisions.
7 / 15
Which process is directly involved in the formation of gametes?
Reasoning: Meiosis produces sperm and egg cells.
8 / 15
Which statement about chromosome number is correct?
Reasoning: This is a fundamental distinction between the two processes.
9 / 15
Genetic variation among offspring is mainly produced by:
Reasoning: Crossing over and independent assortment occur during meiosis.
10 / 15
Which process involves crossing over?
Reasoning: Crossing over occurs in Prophase I of meiosis.
11 / 15
Which process is most important for tissue repair?
Reasoning: Damaged tissues are repaired through mitotic cell division.
12 / 15
A body cell with 46 chromosomes undergoes mitosis. How many chromosomes will each daughter cell have?
Reasoning: Mitosis preserves chromosome number.
13 / 15
A reproductive cell with 46 chromosomes undergoes meiosis. How many chromosomes will each gamete contain?
Reasoning: Meiosis reduces chromosome number by half.
14 / 15
Which process consists of two successive nuclear divisions?
Reasoning: Meiosis includes Meiosis I and Meiosis II.
15 / 15
Which process consists of only one nuclear division?
Reasoning: Mitosis involves a single nuclear division.
