Analysis Mitotic Index In Onion Root Tip Cells

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...

Cell Cycle And Mitosis LAB

purpose of the investigation is to determine the time an onion cell spends in each part of the cell cycle. B. The significance of this investigation is to help us understand and know how long cells are undergoing mitosis. My personal interest is to know the phases of mitosis in cells in order to someday help find cures for cancer. C. The cell cycle is a chronological set of events, culminating in cell growth and division into two daughter cells. Some of the reasons why mitosis occurs include growth...

Using Garlic Root Tips to Observe Mitosis

Mitosis is a cellular process that replicates chromosomes and produces two identical nuclei in preparation for cell division, from the original cell two cells are derived, each of which possesses the same genetic material. Mitosis has five phases: interphase, prophase, metaphase, anaphase and telophase. Interphase The DNA duplicates during interphase to prepare for mitosis. Chromosomes are not clearly discerned in the nucleus. Prophase Chromatin in the nucleus begins to condense and becomes visible...

Garlic Root Tip - Miosis

Inheritance – Mitotic Squash of Garlic Root Tip Mitosis is the process of cell division; it is the process by which a eukaryotic cell separates the chromosomes in its cell nucleus into two identical sets in two nuclei. It is generally followed immediately by cytokinesis, which divides the nuclei, cytoplasm, organelles and cell membrane into two cells containing roughly equal shares of these cellular components. Mitosis and cytokinesis together define the mitotic phase of the cell cycle—the division...

Cell Division

October 2014 Cell Division Mitosis Abstract Mitosis and Meiosis: Cells can be divided in unicellular organisms or in multi-cellular organisms. DNA controls the cell division. Bacteria reproduce by a process called binary fission. Bacteria have one chromosome that's attached to the cell membrane. The chromosome replicates and the two copies separate as the cell grows. Over a period of time this one cell makes two cells. Eukaryotes do the process of mitosis. In mitosis, each daughter cell gets about...

The Amount of Time a Cell Spends in Each Stage of Mitosis

time that was spent by a cell in each of the phases of mitosis. Also, it is used to be able to compare the process of mitosis between plant and animal cells. Background: • Mitosis: This is the process by which a cell duplicates the chromosomes in its cell nucleus in order to generate two identical daughter nuclei. • Interphase: This particular stage is divided into three phases, G1 (first gap), S (synthesis), and G2 (second gap). During all three phases, the cell grows by producing proteins...

Mitosis Write-Up

Mitosis: (onion roots) Root cells are good for observing mitosis; this is because they're in the tip of the root which is an area of the plant that grows quickly. This results in more cells going through mitosis all at once, also allowing us to examine the different stages of mitosis. Stages: 1. Interphase: DNA replicates, but has not formed the condensed structure. They remain as loosely coiled chromatin. The nucleus is still intact. 2. Prophase: The DNA molecules progressively shorten...
