Procedure:You will be given a slide of Allium, which is an onion root tip. Growth occurs when cells divide, so the root tips should have several cells in the process of cell division. Theprepared slidesare placed under a microscope, where the cells undergoing mitosis can be observed at dif...

While this is not necessarily one of the main stages of mitosis, cells in this state can easily be identified by their prominent nucleoli. Diagrammatic representation of an onion root tip cell during interphase:Diagrammatic representation of an onion root tip cell during interphase. Credit: ...
Onion Root TipWhitefish Blastula Prophase Metaphase Anaphase Telophase Mitosis in the Whitefish Blastula Introduction While the onion root cells tend to be arranged in a planar fashion, the whitefish blastula is more spherical. As a result, the whitefish cells are oriented in a less orderly fashion...
This lab was done by observing mitosis in plant and animal cells, comparing the relative lengths of the stages of mitosis in onion root tip cells, stimulating the stages of meiosis, observing evidence of crossing-over in meiosis using Sordaria fimicola, and estimating the distance of a gene ...
Onions are among the world's oldest cultivated plants, and their pungent bulbs have probably been used in cooking since humans have been using fire. A member of the lily family, the onion is thought to be a native of Southwestern Asia but is now grown th
What are the phases of mitosis in a root tip? HYPOTHESIS: Using a prepared onion root slide and a microscope, can you identify, label and count cells undergoing mitosis? METERIALS: -Microscope -prepared slide of an onion root tip PROCEDURE: ...
Onion root tips are commonly used to study mitosis. They are sites of rapid growth, so the cells are dividing rapidly. When an onion root tip is...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our experts can answer your tough...
This is why mitosis is only visible in cells that are dividing, like the whitefish embryo and the onion root tip. Mitosis can take several hours to complete. Scientists will make slides of cells that should be undergoing mitosis in order to find a particular cell in any of the stages - ...
