Why we use hcl in mitosis experiment in onion root tip?
Hydrochloric acid (HCl) is used in the mitosis experiment on onion root tips to hydrolyze the pectin in the cell walls, making it easier to separate the cells for analysis. By softening the cell walls, HCl helps release the individual cells, allowing for better visualization of the chromosomes during different stages of mitosis. This process is crucial for accurately counting and identifying cells in various stages of the cell cycle, providing valuable data for studying cell division and growth.
What is a good substiute stainfor looking at onion root tips under a microscope?
A good substitute stain for looking at onion root tips under a microscope is iodine solution. This stain will help to visualize the cells more clearly by highlighting the cell walls and starch grains present in the root tips.
What are the advantage of longitudinal section of onion root tips commercial slides?
Longitudinal sections of onion root tips on commercial slides allow for the observation of different stages of cell division, such as interphase, prophase, metaphase, anaphase, and telophase. This helps in the study of plant cell division processes. Additionally, these slides provide a clear view of the cellular structures and organization within the root tips, aiding in educational purposes for students studying biology.
Why you need to heat onion root tips during mitosis?
Heating onion root tips during mitosis allows for the cells to be fixed and stained, making it easier to observe and study the different stages of cell division under a microscope. The heat helps to stop any ongoing cellular processes that may impact the accuracy of the observations.
What slide organism in mitosis in plant cell?
The slide organism commonly used to study mitosis in plant cells is the onion root tip. Onion root tips have actively dividing cells that are easily observable under a microscope, making them ideal for studying the different stages of mitosis such as prophase, metaphase, anaphase, and telophase.

How do you dice onions?
Video: How do you dice an onion?The most important thing about dicing an onion is to breathe through your mouth! This will keep you from tearing up while dicing.The first thing you want to do is cut the top off of your onion (NOT the root end). After you cut off the top, then you can grab the edge and peel off the skin of the onion.Hold the onion firmly, but tuck the tips of your fingers inward as not to cut them with your knife. The next thing you are going to do is make parallel cuts on your onion, slicing from the top to the root without cutting through the root. You do NOT want to slice all the way through the onion. Make several parallel slices from top to bottom, getting as close to the root as possible. Make your parallel cuts as far apart as you want your diced pieces to be.Next, turn your onion 90 degrees, and make another series of parallel cuts (from top to root without cutting through) perpendicular to the cuts you already made, so your onion looks like a grid.Then, holding your onion pieces together, place the onion on its side, and start making downward slices.You now have a diced onion!
How i can preserve onion root tips?
Cut 2--3 cm long freshly grown roots and transfer them to freshly prepared fixative, i.e., aceto-alcohol (1:3:: glacial acetic acid : ethanol). Keep the root tips in the fixative for 24 hours and then transfer them to 70% ethanol (for preservation and use in future). Onion root-tip cells have a cell cycle of approximately 24-hour duration, i.e., they divide once in 24 hours, and this division usually takes place about two hours after sunrise. Therefore, roots grown on water should be cut only at that time to score maximum number of dividing cells.
What can you infer about the relative length of time an onion root tip call spends in each cell division?
Based on the onion root tip cells' stages in the cell cycle and relative lengths of the phases, you can infer that the cells spend the most time in the interphase stage, especially in the G1 phase. This is where the cells grow and perform normal functions before entering mitosis for a brief period of time.
