Which model correctly shows the results of mitosis?
a
Model 1 because during mitosis, two daughter cells receive half of the chromosomes of the parent cell.
b
Model 2 because during mitosis, one daughter cell receives the same number of chromosomes as the parent cell.
c
Model 3 because during mitosis, two identical daughter cells receive the same number of chromosomes as the parent cell.
d
Model 4 because during mitosis, four daughter cells receive one quarter of the chromosomes of the parent cell.
c
Model 3 because during mitosis, two identical daughter cells receive the same number of chromosomes as the parent cell.
The correct answer is:
c) Model 3 because during mitosis, two identical daughter cells receive the same number of chromosomes as the parent cell.
To determine which model correctly shows the results of mitosis, we need to understand what happens during mitosis. Mitosis is a process of cell division in which a single cell divides into two identical daughter cells.
In mitosis, the parent cell's chromosomes are duplicated and then divided equally between the two daughter cells. Each daughter cell receives the same number of chromosomes as the parent cell.
Let's review each model and see if it aligns with the process of mitosis:
Model 1: It states that during mitosis, two daughter cells receive half of the chromosomes of the parent cell. This statement is incorrect because in mitosis, the daughter cells receive the same number of chromosomes as the parent cell, not half.
Model 2: It states that during mitosis, one daughter cell receives the same number of chromosomes as the parent cell. This statement is incorrect because mitosis results in two daughter cells, not one.
Model 3: It states that during mitosis, two identical daughter cells receive the same number of chromosomes as the parent cell. This statement aligns with the process of mitosis. In mitosis, two identical daughter cells are produced, and each receives the same number of chromosomes as the parent cell. This model is a correct representation of mitosis.
Model 4: It states that during mitosis, four daughter cells receive one quarter of the chromosomes of the parent cell. This statement is incorrect because in mitosis, two daughter cells are produced, not four, and each receives the same number of chromosomes as the parent cell.
Based on the above analysis, Model 3 correctly shows the results of mitosis.
