Which tool is best for a student to use to observe mitosis in an onion root?
A microscope is the best tool for a student to use to observe mitosis in an onion root tip.
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.
What is the mitotic index for the onion root tip?
The mitotic index for the onion root tip is typically around 18-20%, meaning that around 18-20% of cells in the onion root tip are actively undergoing mitosis at any given time. This high mitotic index is due to the rapid growth and development of the root tip.
Why do all of the phases of mitosis happen at the same time in an onion root?
Different individual cells will have received slightly different amounts of vital nutrients at different times, therefore, mitosis will not occur at the same rate throughout the onion. Over time, cells will become more out-of-sync and end up mitozing at different times causing each cell to be at different stages of the mitotic cycle. P.S. Is mitotic even a word - I've never heard it before. Sounds like a smug biology teacher made it up.
What is the use squashing onion root tip?
Because it makes the onion root tip very thin - to get best results they tend to try and make it one cell layer thick. This way when you look at under a microscope with dye on it, we can see it clearer and more accurately. You can then distinguish between anaphase, interphase and so on. (:
Which tool is best for a student to use to observe mitosis in an onion root?
A microscope is the best tool for a student to use to observe mitosis in an onion root tip.
Bella did the onion root mitosis lab before on what?

Why are onion root tips used to look at mitosis instead of other parts of the onion?
because of you!
What type of cell division is exhibited by the cell in the onion root tip?
Mitosis.
What is a blatsula?
It is a type of white fish that demonstrates mitosis much like an onion root tip.
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.
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.
How does mitosis differ between the onion root and the roundworm?
The only difference between vegetal (onion) cells and animal (roundworm) is not quite in mitosis, but in citokinese (not a mitosis phase since mitosis refers to nucleus division). Vegetal cells have a thick wall rounding the cell which needs different means to split than the membrane in animal cells
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 part of an onion root tip has the greatest rate of cell division?
The meristem, located at the tip of the root, has the greatest rate of cell division in an onion root tip. This region is responsible for the growth and elongation of the root, leading to the production of new cells through mitosis.
What plant part of a plant does a onion come from?
the root the root No the root is below the ground and the green onion is above the ground which is a young onion. it will eventually grow into a onion.
Use of acetocarmine in onion root tip squash?
Acetocarmine is a DNA specific stain like feulgen stain, so the super coiled chromosomes during different stages of mitosis present in the Onion root tip cells can be visualized perfectly by treating with this stain.
