Pre-Lab Questions. 1. Provide the correct order for the stages of mitosis. interphase prophase metaphase anaphase telophase. 2. Why are root tips excellent observation points for mitosis? Answers will vary. Sample answer: The root tip of a plant contains actively dividing cells, making root tips excellent observation points for mitosis.
(Mitosis) Introduction: In this lab, you will examine the dividing root-tip cells of an onion. You will examine the. specimen to identify the various phases of the cell cycle, to see which phases cells spend. more time in, and you will answer related analysis questions to further your understanding of the eukaryotic cell cycle. Pre-lab:
In this lab, you will be looking at the cells in an onion root tip. Purpose: To see if each phase of mitosis happens for an equal amount of time in onion root tip cells. Materials: You will choose materials for your experiment from the following: Microscope, prepared onion root tip slide, ruler Procedures: 1.
Why onion root tip for lab experiment? The onion roots grow rapidly in large number. The cells at the tip are actively dividing and therefore all cell cycle stages are easy to visualize in single preparation. The onion tips are easy to prepare for squashing on microscopic slide. The slide preparation can be stained to make them more observable.
Answer key to the worksheet on mitosis in an onion root, labels the graphic and describes the phases of the cell cycle.
The document includes questions about the cell cycle and mitosis that students answer, along with a reflection on what was learned. 1. The document describes an activity where students classify onion root tip cells into different phases of the cell cycle based on images.
In this simulation, you will:-Place sketches of the different phases of mitosis in the correct order and label them.-Match micrographs of cells undergoing mitosis to the correct phase name.-Look at a microscope slide of the tip of an onion root and identify cells undergoing mitosis.
