Observation of mitosis in garlic root tips Abstract The purpose of this experiment was to establish the different stages of mitosis which occur in the tip of a garlic root. The root tip which was used had already been pre-stained with an aceto-orecein stain. The stain made the root tips more visible so that under a light microscope it would be much easier to distinguish where the root tip was. While under the light microscope the objective was to be able to identify and distinguish each of the stages

• Why are the process of mitosis and meiosis both important to a living organism? Living organisms need cell division in order to grow and reproduce. Mitosis and meiosis are two types of cell division. Mitosis occurs in vegetation cells‚ while meiosis occurs in reproductive cells of animals. In mitosis‚ a parent cell divides into two identical daughter cells that are the same as the parent cell. Meiosis produces four daughter cells that contain half of the genetic information of the parent

process of mitosis‚ which is the process by which cells of tissue are created for living creatures. When meiosis occurs 4 daughter cells are created‚ while only 2 are created in mitosis. With the creation of 2 daughter cells the new cells will be similar to the parent cell‚ but will have differences‚ as there more parent cells involved. When mitosis occurs the daughter cells will be identical to the parent cell‚ since only 1 cell is involved. Meiosis is needed for sexual reproduction‚ while mitosis is needed

The Building Blocks of Life Worksheet Part 1: Mitosis and Meiosis Short-Answer Response Why are the process of mitosis and meiosis both important to a living organism? The process of mitosis and meiosis are both important to a living organism because without them a cell would not be able to reproduce. Mitosis is an asexual process used to replace old and dead cells with new ones by dividing into two identical daughter cells. Meiosis‚ however‚ is the step that makes sexual reproduction possible

Cell cycle checkpoints are control mechanisms in eukaryotic cells which ensure proper division of the cell. The Cell Cycle consists of three checkpoints. These checkpoints are the G1 checkpoint‚ the G2 checkpoint‚ and the M checkpoint. These checkpoints all have different functions. Cells have many different mechanisms to restrict cell division‚ repair DNA damage‚ and prevent the development of cancer. Cancers are formed as cells acquire a series of mutations‚ or changes in DNA‚ that make them divide

PR OCEDURE Before beginning‚ set up a data table similar to the Data Table: Experiment Results in the Lab Report Assistant section. This experiment will create a reaction of sodium carbonate and calcium chloride dihydrate to produce a precipitate of calcium carbonate. This formula is: Na2CO3(aq) + CaCl2. 2H2O(aq) à CaCO3(s) + 2NaCl(aq) + 2H2O 1. Put on your goggles. 2. Weigh out 1.0 g of CaCl2·2H2O and put it into the 100-mL beaker. Add 25 mL of distilled water and stir to form the calcium
