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

SURFIN’ THROUGH STAAR Session 2: Cellular Processes Background Information: Cell Transport When molecules move from a high to low concentration it is called moving DOWN the concentration gradient. When molecules move from a low to high concentration it is called moving AGAINST the concentration gradient. When the concentration of a solute is the same throughout a system‚ the system is at EQUILIBRIUM. What kind of transport DOES NOT require energy? PASSIVE What kind of transport requires

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

Alvaro Comino LAB REPORT 4 CONNECTIVE TISSUE (SPECIALIZED) I. Abstract In this experiment‚ identification and classification of different types of connective tissue was performed. Also‚ cells and extracellular matrix was to be identified in them. For this‚ different already prepared slides were chosen and observed under the microscope to then identify the different parts. II.

on five different chromosomes 13‚ 14‚ 15‚ 21‚ 22. Chromosomes also contain DNA-bound proteins‚ which serve to package the DNA and control its functions. During the G1 stage of the cellular cycle‚ all chromosomes must replicate themselves ready for mitosis. During the early stages of G1 each chromosome bearing rDNA repeat forms its very own NOR. The NOR have the ability to fuse together and form a single large nucleolus. In a typical eukaryote‚ a rRNA gene consists of a promoter‚ internal and external
