Exercise 13 MITOSIS: REPLICATION OF EUKARYOTIC CELLS ANSWERS TO QUESTIONS 1. a. Mitosis and cytokinesis are often referred to collectively as "cellular division." Why are they more accurately called cellular replication? The result of mitosis is production of two cells (replicates) identical to the parent cell. The genetic material is replicated rather than divided. b. Does the cell cycle have a beginning and an end? The organization of our study of cellular events indicates a beginning and

Biology (CP8121) Experiment 2: Observing Mitosis and Meiosis on cell specimens (Formal report) Name: Wong Chung An Class: DMLS/FT/1B/02 Admin number: P1138687 Summary This experiment aims to observe mitosis and meiosis on cell specimens. It involves the modelling of the stages of meiosis and also the staining procedures to identify mitosis in onion root tip. There are two parts to the procedure of the experiment whereby the first is staining and observing mitosis in onion root tips and the second being

Normal cell division meiosis and gamete production via meiosis. Explain why the process of mitosis and meiosis are both important to a living organism. When would an organism need to undergo the process of mitosis? Meiosis? What would happen if meiosis did not occur? Mitosis is the cell process of growth and division whereas meiosis is the process of developing reproductive cells. The sperm and egg are critical components for almost all living organisms. Every living organism begins with one

Mitosis and meiosis are both important biological processes that happen within eukaryotic cells. These two processes are slightly different from one another‚ but have a lot of similarities. Before each of these processes can be performed‚ the cell first has to go through interphase. Interphase is considered the primer for mitosis or meiosis and consists of: G1‚ S‚ and G2 phases. These phases prepare the cell for either mitosis or meiosis by causing the cell to grow‚ copy the DNA‚ and copy the cell’s

are two main types of cell division: (1) mitosis and (2) meiosis. (Balls 34) Most cells are produced by a process called mitosis. In mitosis‚ a cell divides and forms two identical daughter cells. (Prescott 102) Each daughter cell then doubles in size and becomes capable of dividing. Most one-celled plants and animals reproduce by mitosis. (Baserga Biology 56) This is also the way most cells in your body and multi-cellular plants and animals reproduce. Mitosis in animal cells takes place in four orderly

There are two processes of cell division that are very tricky. They are mitosis and meiosis. Many people often get confused with the two about their functions. They both serve as mechanisms for cell division. However‚ quite significantly‚ they are very much different in fact and occur in different situations. Mitosis and meiosis take place in different places. This is one of the first major differences between the two. Mitosis takes place within somatic cells (cells that make up the body)‚ while

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

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

Bacterial Morphology MLT1 Task 11- Lab 2 Johnny Archuleta Western Governors University Question A and C answers. A wet mount stain is when a drop of water is placed onto the microscope slide. The water on the slide helps to support the organism and sample. The water fills the space between the cover slip and the slide. This action allows the light from the microscope to pass through the slide and the sample for better visualization of the organisms. A direct stain occurs when a charged
