Lab 3: Mitosis and Meiosis Purpose: The purpose of this lab was to recognize the stages as well as events of mitosis and meiosis in a plant cell or an animal cell. The relative duration of each stage in the cell cycle will also be learned during this lab. By doing this lab we will also create a model of and understand the process of crossing over. This lab also helps students understand the similarities along with differences between mitosis and meiosis. Hypothesis: I predict that

USE OF ONION ROOT TIPS FOR MITOTIC DIVISION OBSERVATIONS Introduction The zone of cell division on the onion root tip is a great place to observe mitotic cell divisions. Through the observation and comparison of different regions of the root tip‚ the duration of mitotic stages and mitotic indexes are determined for the various divisions of the root tip. Methods Each group used a compound microscope to analyze the different sections of the onion root tip. The root tip was visually

The eukaryotic cell cycle is the process that starts just as a cell is first formed from a dividing parent cell and then carried on until its own cell division (Simon‚ Dickey‚ Reece‚ page 125). The first stage involved in the eukaryotic cell cycle is called interphase. Interphase is the period between divisions that has 3 separate phases. The first phase in interphase is G1‚ where G stands for gap‚ and in this phase the growth of cell parts occurs and materials needed for transcription‚ translation

Results: Somatic cells multiply through mitosis resulting in diploid‚ identical cells and meiosis provides for genetic variability along with haploid daughter cells‚ gametes‚ or sex cells. Most of the cells observed on the root tip were in interphase. Table 3.1 helped analyze the number of cells that are going through each phase of the cell cycle and helped estimate the amount of time it took for each cell to complete that phase. Table 3.2 compared and contrasted mitosis and meiosis. Conclusion:

Rooms Division In a statistics conducted by the U.S. Lodging Industry in 1995‚ it has been shown that the majority of hotels revenues (60.2 %) are generated from Rooms Division Department under the form of room sales. This very department provides the services guests expect during their stay in the Hotel. Lastly‚ the Rooms Division Department is typically composed of five different departments: a) Front Office b) Reservation c) Housekeeping d) Uniformed Services e) Telephone FRONT OFFICE Is the
