In the experiment, onion root tips are choosen to be observed under microscope. It is because the chromosomes are larger than most of the others plants. The root tips of onion are picked to observed as the root tips are the region where the cell division occurs mostly. The cells at the tips of the o
USE OF ONION ROOT TIPS FOR MITOTIC DIVISION OBSERVATIONS
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...
Why is the root tip used?
This is the region of active cell division by mitosis
Why is hydrochloric acid used?
Breakdown the pectins in the middle lamella that hold the cells together. Helps produce a preparation that is one cell thick.
Why is the stain used?
-makes chromosomes more visib
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 t

Mitosis occurs in all eukaryotic cell tissues and produces genetically identical daughter cells with a complete set of chromosomes. In humans, mitosis produces somatic cells that are diploid, which means they contain two non-identical copies of each of the twenty-three...
Lab 3: Mitosis and Meiosis
The purpose of this lab was to recognize the stages as well as events of mitosis and meiosis in a plant cell or an animal cell. The relative duration of each stage in the cell cycle will also be learned during this lab. By doing this lab we will also create
CELLULAR DIVISION AND REPLICATION WITHIN MITOSIS AND MEIOSIS
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 lo
EUCARYOTIC CELL DIVISION: MITOSIS AND MEIOSIS

BINARY FISSION: Procaryotic cells (bacteria) reproduce asexually by binary fission. Bacterial cells have a single circular ch
The Cell Cycle
1) The centromere is a region in which
A) chromatids remain attached to one another until anaphase.
B) metaphase chromosomes become aligned at the metaphase plate.
C) chromosomes are grouped during telophase.
Purpose: The purpose of this lab was to calculate the amount of 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.
• Mitosis: This is the process by which a cell duplicate
Mitosis (onion root tip cell)
Arshya & Shruti IBDP YR 1A
Aim: to observe the stages of mitosis for a given onion root tip cell under a fixed focus of 40x
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.
Practical 1: Observation of mitosis in garlic root tips
The practical will involve the preparation, observation, and classification, of the various stages of mitosis by observing garlic root tips using a microscope. The study comes under the heading of cytogenetics which is...
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 teloph
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
It was discovered in 1858, by Rudolf Virchow, that new cells can only arise from previously existing cells. This is done in two ways: mitosis and meiosis. Somatic (body) cells divide exclusively by mitosis followed by cytokinesis, while germ cells produce gametes by the...
