What Makes Onion Roots Ideal for Studying Mitosis? Onion roots are ideal for studying mitosis because onions have larger chromosomes than most plants, making the observation of cells easier. The roots of plants also continue to grow as they continue to search for water and nutrients.
Similarly, why is Allium Cepa used in studying mitosis?
The plants usually have the large chromosomes and the low chromosome number. The root meristem contains a high proportion of cells in mitosis (1-3). The growing root tips of the onion, Allium cepa provide a readily available source of material for studying the damaging effects of chemicals on chromosomes.
Consequently, what is the purpose of using HCL in mitosis experiment?
4 – the purpose of the hydrochloric acid is to destroy the substances that unite the cells (usually pectin), but it does not destroy the cell walls. The hydrochloric acid also has the ability to kill the cells and halt the process of mitosis.
The plant tip cells are used because the root area is a place of rapid mitosis, where cells are actively dividing. The animal cells showed the decrease from prophase to metaphase, but the duration does not decrease in anaphase and telophase (data stays almost constant).
