Onion meristem cells complete a cell cycle in 800 minutes. Use the data in the table to calculate the portion of the cycle spent in prophase.

A researcher examining a root tip observes a plant cell with condensed daughter chromo- somes at each pole and a cell plate at the central plane of the cell. Which of the following best describes what will occur next in the cell? A The nuclear envelopes will break down, and the spindle fibers will begin to form. B с D Sister chromatids will align at the central plane via spindle fibers. The nuclear envelope will break down, and the spindle will begin to form. The chromosomes will decondense, and the daughter cells will enter the interphase.

Using my chart attached, can you please help me answer this question? According to your results, what porportion (or percentage) of time do onion root cells spend in Mitosis?

Please asap

Which event occurs in S-phase? Question 4 options:   Mitotic spindle is created.   Normal growth and cell function   Energy stores are replenished   Karyokinesis   None of the above

Find at least one cell in this fish embryo to represent each of the phases below. Interphase Prophase Metaphase Anaphase Telophase Label your images of the specific cell phases.

Count 100 cells and tally them. Remember the phases you learned in Bio 31 and Anatomy? Draw a pie chart graph showing the phases of Allium root tip. Label each of the phases with the % for each phase: prophase metaphase anaphase  telophase interphase provide direction of the phase progression--direction in which to read the graph so the phases of mitosis are in proper order.

Match the image with each phase of the cell cycle.

Draw a simple model of a cell shortly before centrosome duplication and draw a representationof the centrosome cycle through two rounds of the cell cycle (until you have 4 cells). In eachdivision note the plane where the contractile ring will bisect the spindle.
