Procedure: in the mitosis lab, i worked with my partner mike to take pictures of cells so we could analyze the data and find results this started with getting an onion root tip on a tray, and then looking at it through different magnifications. Biology lab name date per observing mitosis introduction: all cells undergo a process of growth and division called the cell cycle the cell cycle consists of three major stages: using middle power on your microscope, focus on the apical meristem of the onion root tip this is the area just behind the root cap 3 switch to high power.

Pre-lab presentation for biology honors (gr 9), observing stages of mitosis using prepared onion root tip slides includes materials, safety, background info from the worksheet, procedure includes photos of onion cells + mitosis diagram from text. Onion root tips are a good medium for observing and studying mitosis for three main reasons first, they are cheap and easy to obtain a lab class needs little funding in order to purchase large quantities of this medium. I am doing a lab in biology on onion root tip mitosis and i am having trouble completing the table which contains the number of each of the phases (inter-phase, pros-phase, meta-phase, ana-phase, and telo-phase) and the percent of each phase in a one single cell.

Mitosis is best observed in cells that are growing at a rapid pace, such as in the whitefish blastula or onion root cell tips the root tips contain a special growth region called the apical meristem where the highest percentage of cells are undergoing mitosis. Hi friends, here i am with another video this video will help how to do onion root tip experiment to study mitosis in upcoming videos i will teach you how to score full marks in biology practical. Mitosis onion root tip lab onion root tip mitosis mitosis report part mitosis in onion root tips biology lab report 1 gatsby synthesis essay extracting dna from strawberrys experiment - philip harris lab 3 plant pigments and photosynthesis lab report documents similar to stages of mitosis lab report lab report number who knows. Mitosis is part of a larger process called the cell cycle when a living organism needs new cells to repair damage, grow, or just maintain its condition, cells undergo the cell cycle in this lab you are going to determine the approximate time it takes for a cell to pass through each of the four stages of mitosis.

Take the onion plant with newly sprouted roots and cut two root tips using scissors and transfer them into a plastic microfuge tube fill 2/3 of the tube with 1n hcl using a dropper place the tube in a 60°c water bath and incubate the tube for 12- 15 minutes. Practice locating each of the stages of mitosis in the following slides of the onion root tipeach picture contains at least on cell at each stage of mitosis some stages are represented by multiple cells. The preparation of onion root tip freezes the mitosis process at one point, thus, the higher the percentage of the cell in one stage , the higher the time spent on that stage based on table one, interphase recorded the highest number of cell followed by anaphase, metaphase and telophase. Mitosis lab objective: in this lab, you will determine the approximate time it takes for a cell to pass through each of the four stages of mitosis.

Root tip mitosis page - rtm1 mitosis in onion root tip cells a quick overview of cell division the genetic information of plants, animals and other eukaryotic organisms resides in several (or. In biology labs, students use onion root the mitosis of onion root tips involves the process of cell division in its various phases, such as interphase, prophase, anaphase, metaphase and telophase. Explain why the whitefish blastula and onion root tip are selected for a study of mitosis blastula and root tips are where the creation of new cells happens that is where the cells split and is where nuclear replication is the most frequent. The stages of mitosis can be examined in whitefish blastula and onion root cell tips by using a microscope the process of crossing over and the stages of meiosis only occur during the creation of gametes and spores.

Biology mitosis lab report onion root

An onion root tip is a rapidly growing part of the onion and thus many cells will be in different stages of mitosis the onion root tips can be prepared and squashed in a way that allows them to be flattened on a microscopic slide, so that the chromosomes of individual cells can be observed easily. Mitosis in onion root tip the meristamatic cells located in the root tips provide the most suitable material for the study of mitosis the chromosome of monocotyledonous plants is large and more visible, therefore, onion root tips are used to study mitosis. Explain why the whitefish blastula and onion root tips are selected for a study of mitosis the blastula is a hollow ball of cells that forms from the fertilization of an egg rapid growth occurs and numerous cellular divisions making mitosis in various stages easy to observe.

This graphic shows an image of what cells in an onion root tip would look like as they are in various stages of mitosis this worksheet compliments a laboratory activity where students look at onion root tip slides to identify phases of mitosis this worksheet could also substitute for that lab if students were absent or classes that don’t have access to materials. Title- mitosis abstract –for this lab there is no experiment to be done only questions to be answered in this experiment we will categorize and count the cells to compute the mitotic index of the total root area introduction – the purpose of this experiment is to answer questions associated with the onion root tip photos that are pictured in the lab. The allium roots need to be prepared 1-10 days in advance of the lesson some practitioners report that cutting the root tips around noon makes a difference to the mitotic index, so you may want your technician to cut and ‘fix’ the tips in ethanoic alcohol rather than ask your students to carry out this step.
