In the table above, a teacher wrote out descriptions of the different phases of mitosis. She then asked her students to put the phases in the correct order that they occur during mitosis. Which of the following would be the correct answer?
This model of the cell cycle includes two arrows that each represent a process in the cycle.
What do the two arrows represent?
A student accidentally cuts their finger while preparing food. After a few days, the wound begins to close as new skin forms. Which statement best explains the role of the cell cycle in this process?
Which correctly describes what is occurring at the four different stages of the cell cycle?
Below is a student drawing of the cell cycle. The student made an error in their cell cycle diagram.
What is the name of the missing phase, AND explain what important event happens during that phase.
Read the question carefully. Then enter your answers in the box provided.
Cell division is regulated by a variety of internal and external signals. What reasons might a cell undergo cell division?
Select THREE answers.
A student observed an onion root tip cell under a microscope and made the following observations.
Sister chromatids are separating
Spindle fibers are attached at the centromere
There is no visible nucleolus
What phase of the cell cycle is this student MOST LIKELY observing?
The life cycle of a frog is illustrated in the diagram.
Which statement best explains how the cell cycle is important to the life cycle of the frog?
The diagram shows the major stages of the cell cycle and the percentage of time spent in each phase.
Which statement best describes why a cell spends the majority of its time in interphase?
A mutation causes a defect in the protein structures located on the centromeres of chromosomes. As a result, spindle fibers can’t attach to chromosomes during metaphase.
Which structure is directly affected?
In a lab simulation, the spindle fibers form correctly, but they fail to shorten and pull chromatids apart during anaphase.
What problem will this cause for the daughter cells?
