AND REPLICATION WITHIN MITOSIS AND MEIOSIS ABSTRACT The processes of mitosis and meiosis were examined along with their frequency as well as each of the different steps and their time duration. It was found that the interphase stage of both mitosis and meiosis was the longest of all the stages as this was where most of the ‘action’ was happening such as cell growth and duplication of all cell organelles and chromosome replication also. It was also found that mitosis and meiosis have similar

Mitosis and meiosis are the means by which reproduction takes place. Mitosis creates an exact duplicate of cell so that old cells can be replaced‚ such as in skin‚ hair‚ and bones. Meiosis allows a cell to unite one half of its genetic makeup with a cell from another partner to create an entirely new organism. Mitosis Mitosis is the process by which two daughter cells are formed‚ each containing a complete set of chromosomes. Mitosis is the process by which an organism creates new cells‚ such

Mitosis in Plant and Animal Cells OBJECTIVES Observe and identify cells undergoing the process of mitosis. Compare the stages of mitosis in plant cells with these stages in animal cells. MATERIALS • compound light microscope • prepared slides (longitudinal sections of onion or garlic root tips) • prepared slides (whitefish blastula or other animal tissue) Procedure PART 1: MITOSIS IN PLANT CELLS 1. Observe a prepared slide of a longitudinal section of onion or garlic root tips. Use low

Abstract: The question of the investigation is if lectin can induce mitosis in the cell of an onion root tip. The hypothesis is that‚ if the lectin does not induce mitosis‚ then there should not be a great change in the number of cells that undergo mitosis. The alternate is‚ if the lectin does induce mitosis‚ then there should be an increase in of cells in mitosis. The control group of the experiment had root tip treated with water‚ and the experimental had root tip treated with lectin. Upon the

of interphase to the end of telophase lasts about 24 hours. The mitotic index (MI)‚ which is the percentage of cells undergoing mitosis‚ was determined for each division of the root tip. In order to determine the mitotic index for each region‚ the total number of nuclei must first be determined‚ and from that number‚ the number of cells undergoing some stage of mitosis must be determined. Knowing both numbers from a section allows for the calculation of the mitotic index. Knowing the mitotic index

work we are going to present why the statistics are important in business‚ generally in big companies that need that data to help the to improve their sells and the product they make. With this data the professionals also can make graphics to help the crew to understand better what they need to improve on the product‚ or maybe low the price. Approach to the problem: Why the statistics are important in business? Hypothesis: I think that the statistics are important in business because they help

Why Termite Control is Importance? Termites are infamous due to the damage they cause. Every year they cause damages of millions of dollars in Australia alone. The worst part is that these are difficult to control without the help of a professional as they spread quickly. Termites can cause a major damage to your house and office. These damages are caused slowly and over the period of time‚ before you know it the damage is already done. Thus‚ termite control is important to control termites from

Written Paper Number 1 Topic: Why is it important to learn English? Almost every pupil in Germany learns English in school. Most of them start to learn this language in the 4th grade of elementary school and don’t stop to learn it until the 10th grade of secondary school or 12th grade of gymnasium. There are some reasons why pupils learn English from the beginning of their school live. It is very important to learn English. First of all English is the most used language. When people with

Why is correctional counseling important? It is important to assure that criminals still get the best help possible‚ counselors do not only advise and mentor them‚ but also help them live a normal life after being released from prison‚ jail‚ private corrections‚ or juvenile facilities. Without correctional counselors‚ offenders would not know how to change to be successful in society and they would struggle rehabilitation or relapse soon after being released. Many would be jobless‚ possibly homeless
