Practise AP Biology 4.5.B questions by tracing mitotic chromosome movements and explaining how spindles and cytokinesis produce daughter cells.
A student collected samples of cells from a woody plant during the spring and produced the drawings below. Sample 1 was collected from the woody stem of the plant. Sample 2 was collected from the root tip of the plant. Cells in different steps of mitosis are labeled with letters A, B, C, D, and E in Sample 2.
Figure 1. Drawings of samples of plant cells collected from two locations in a woody plant during the spring
Describe the role of mitosis in the growth of a plant.
Refine the model in the space provided for your response by using the letters from four of the cell labels of Sample 2 to represent the sequential steps of mitosis.
Explain how the arrangement of cellular components during the step of mitosis portrayed by cell D in Sample 2 facilitates the proper distribution of chromosomes to the two daughter cells.
