Multiple Choice
Which of the following best describes the primary purpose of mitosis in multicellular organisms?
A
To increase genetic variation through crossing over
B
To synthesize ATP for cellular energy
C
To produce genetically identical daughter cells for growth and repair
D
To generate gametes with half the number of chromosomes
Verified step by step guidance1
Understand the concept of mitosis: Mitosis is a type of cell division that results in two genetically identical daughter cells. It is essential for growth, repair, and maintenance in multicellular organisms.
Eliminate incorrect options: Crossing over occurs during meiosis, not mitosis, and is responsible for genetic variation. Therefore, 'To increase genetic variation through crossing over' is incorrect.
Evaluate the option about ATP synthesis: ATP synthesis is a function of cellular respiration, not mitosis. Thus, 'To synthesize ATP for cellular energy' is not related to mitosis.
Consider the purpose of gamete generation: Gametes are produced through meiosis, which reduces the chromosome number by half. Mitosis does not generate gametes, so 'To generate gametes with half the number of chromosomes' is incorrect.
Identify the correct purpose: The primary purpose of mitosis in multicellular organisms is to produce genetically identical daughter cells for growth and repair. This ensures tissue maintenance and organismal development.
