Mitosis in garlic root tips

Under light microscope, the chromosome of the cell is non clearly seeable but still can be observed. Students may also wish to carry out further investigations using plants such as hyacinth, onion and broad bean: In plants, the root tips continue to grow as they search for water and nutrients.

Therefore, detecting mitosis in works cell is much better and easier.

Onion Root Cell Cycle Lab Answers

This is based on the fact that during Interphase, cells are carrying out protein synthesis and DNA replication which would require more time than the other phases of mitosis.

To calculate this, the number of cells in one phase was divided by the total number of cells of that area and then multiplied by The chromosomes migrate and line up themselves on the equator metaphase home base.

I chose a simple procedure that can be carried out using materials that are easily found in the home. The typical chromosomes become dispersed in interphase, in the signifier of chromatin non seeable.

The exception is Toluidine blue which however can be bought in shops that sell materials for chemical and biological laboratories.

The consequence obtained can non even been analyze. Spindle fibers align the chromosomes along the middle of the cell nucleus. Then the magnification was adjusted to X so the cells and any condensed chromosomes could be clearly viewed by the experimenters.

In this experiment, my group was assigned to transport out the 2nd method, by utilizing orcein ethanoic in order to stain the chromosome of the garlic root cells.

The hydrochloric acid also has the ability to kill the cells and halt the process of mitosis.

What conclusion do we get from doing the onion experiment to see mitosis?

It start when the chromosome arrive at the pole of the cell. Mitosis can take several hours to complete. This procedure of maceration that permits the disassociation of the cells of the vegetable tissues, can also be tried for other reasons. Mitosis is a one portion of the cell cycle.

Rates of Mitosis in Onion Root Tips

Students will study the cellular steps involved in DNA replication and cell division in both mitosis and meiosis. Students can examine the stages of mitosis in the preparation of plant root tips. Crossing over in meiosis will also be investigated through the use of Sordaria cultures.

Mitosis in Onion Root Tips. Onion root tips are extremely popular for viewing the different phases of mitosis because the chromosomes are large and and very dark when stained.
