Onions like all plants grow primarily at the tip which is called the apical meristem. Since onions do not branch out, there are no lateral meristems as there would be on a branched plant, so almost all growth is at the tip.

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.
Nails grow from an area of rapidly dividing cells known as the nail root. The nail root is located at the tips of fingers and toes. During cell division, the cells of the nail root fill with keratin and produce a tough, platelike nail that covers and protects the tips of fingers and toes.
Most people would inform that growing onion could be done in any area throughout the winter but it is important that considerations be given when planting them. One of the factors to consider when planting is about the place where you stay like if you live in the South or the North. The long day onions would be a good choice to plant if you live in South. Typically this would need about sixteen 16 hours of exposure to sun each day. For those who live in the north, it would be best to use those short day onion types that require twelve hours of sun to grow. Also try to get some tips from Nurseries or other gardeners in the area.

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.
Onions are commonly used to observe mitosis because their root tips contain rapidly dividing cells, making it easier to identify the stages of cell division. The tips are also rich in meristematic tissue, where cells are actively dividing. Furthermore, the large size of onion cells allows for clear visualization of the chromosomes during various phases of mitosis. This makes onions an ideal specimen for studying the process of cell division in a classroom or laboratory setting.

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.
