Question
Chapter 19.5, Problem 3CYP
Summary Introduction
To analyze:
How does a close examination of metaphase indicate if a cell is undergoing mitosis or meiosis?
Introduction:
During the zygotene stage of prophase I of meiosis, homologous chromosomes are paired. The process is called synapsis. Mitosis does not include the pairing of homologous chromosomes.

Chromosome number of daughter cells
Stages
Synapsis
Crossing over
Cell type
Number of cells formed
Genetic consequences
Explain how interference with mitotic structures or disruption of mitotic processes affects cell reproduction and ultimately the organism.

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 F show an early and a late stage of the same phase of mitosis. What phase is it? 2) Which cell is in metaphase? 3) Which cell is in the first phase of mitosis? 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 or animal cells? Explain your answer. 8) What is the longest phase of the cell cycle? 9) Why is mitosis important?arrow_forward
- Draw diagrams for each phase of Mitosis in the correct order. Including Mitosis as part of the cell cycle is beneficial but not required. Identify the most important relevant details about each phase. There are at least 2 details or terms associated with each phase. Please use the proper names for parts such as centromeres, spindle fibres, etc.arrow_forwardList in each blank the description of events associated with each stage of mitosis in addition to the preparatory stage Interphase.
