A student claims that interphase is the longest stage of the cell cycle. Another student claims that mitosis is the longest stage. Using evidence from the photo, determine which student is correct and why. A) Mitosis is the longest stage because anaphase requires more time to separate chromatids. B) Interphase is the longest stage because chromosomes are visible in the majority of the cells. C) Mitosis is the longest stage because the majority of the cells in the photo are replicating their DNA. D) Interphase is the longest stage because the majority of the cells in the photo have uncondensed chromatin and are not dividing. Not Gradedarrow_forward
- Why is this technique used?arrow_forwardBelgy Name: Date: Period: Mitosis Worksheet The diagram below shows six cells in various phases of the cell cycle. Note the cells are not arranged in the order in which mitosis occurs and one of the phases of mitosis occurs twice. Use the diagram to answer questions 1-7. Phases of the Cell Cycle 1) Cells A and early stage of the same phase of mitosis. What phase is it? 2) Which cell is in mg 3) Which cell rst phas sis? 4) In cell A, what structure is labeled X? 5) Which cell is in the "in between" phase of mitosis? 6) Place the diagrams in order from first to last. 7) Are the cells depicted plant animal cells? Explain your answer. 8) What is the longest phase of the cell cycle? 9) Why is mitosis important?arrow_forwardThree actively growing cultures of the same strain of yeast (saccharomyces cerevisiae) are used. Culture A has been incubated for 48 hours and Culture B has been incubated for 24hours and Culture C for 6 hours. a) Make a drawing of the cells from each culture to identify the various stages of the cell division. b) Is there any difference between the 3 cultures?arrow_forward

Based on the information in the graphs, infer how cancer cells differ from typical, noncancerous cells. Select ALL that apply. A) Cancer cells do not replicate their DNA. B) Cancer cells replicate their DNA too quickly. C) Cancer cells do not go through interphase during their cell cycle. D) Cancer cells spend more time dividing compared to typical cells.

Sample 1 was collected from the woody stem of the plant. Sample 2 was collected from the root tip of the plant.
