Cell Onion Plant Lab Report

Almost all plants have roots that grow into the soil to help support its life. Roots are used by the plants to take nutrients and water out of the soil and send it through the plant. They also stabilize the plant. The root is made up multiple parts starting at the bottom with the root cap, then the zone of cell division next is the zone of cell elongation, and at the top of the root is the zone of differentiation. To figure out what section of the root has the highest number of cells in mitosis we did an experiment where we found out cells that are closer to the root tip are more likely to be doing mitosis than the cells that are further away from the root tip.

Through the experiment, we looked at the zone of cell division, which is
When doing this individually I found that there were 30 cells in the process of mitosis in the zone of cell division and only 9 in the area of cell elongation. The number of cells in mitosis counted in each section of the onion root proves that there were more cells in mitosis in the zone of cell division than the zone of cell elongation. This proves the point that there is more mitosis in the zone of cell division than the other areas of the
Through both individual research and the class average after the experiment was performed the data proved that there was a much higher percentage of cells in mitosis in the area of cell division then the zone of cell elongation. The reason this is the case is that roots grow from the bottom and the zone of cell division is closer to bottom of the root. Even though we only tested an onion root tip these same results would happen with other plants because all roots have the same purpose to take nutrient and water out of the soil and into the plant. This means that the roots will be growing in the same way from the bottom meaning there will be more mitosis happening in the zone of cell division than the other parts of the
