AP Bio Lab 3 Help! 10 points best answer!?
If you write a lab / writing lab reports and write me please:)) Thank you !!!!! couturechic16@yahoo.com
1. Explain how mitosis leads to 2 daughter cells, each of which is diploid and genetically identical with the original cell. What activities occur in the cell during interphase?
2. How does mitosis differ in plant and animal cells? How does the plant mitosis accommodate a rigid wall, the rigid cell?
3. What is the function of the centrosome (the area) of the centrioles? Is it necessary for mitosis?
1. When her comments were not divisive to the area of the root tip limited use, as the results were different?
2. Based on the data in T3.1 power, what can we conclude is the relative length of time an onion root tip cell in each stage of cell division?
3. Draw and label a diagram of the cycle of the onion root tip cells with the data in Table 3.1

1. Explain how mitosis yields two daughter cells, each of which is diploid and genetically identical with the original cell. What activities occur in the cell during interphase?
During interphase, through the first step in the process of mitotic chromosomes synthesis and make an identical copy of itself. These copies are fused at the centromere and are called sister chromatids. During mitosis, the centromere is also replicated. Immediately after this happens, the distribution of the two copies. Then the cell divides into two daughter cells. Each cell now has an identical copy of the chromosomes of the cell of origin.
2. How does mitosis differ in plant and animal calls? How does the plant mitosis accommodate a rigid wall, the rigid cell?
In animal cells, during telophaseA groove Division. In plants, it is not, but a plate of the cell begins to form. This is the cell wall of two new cells. Thus, the cell wall is produced by the plant mitosis. In animals, creating centrioles, the spindle fibers pull the chromatids of the other sisters. In plants, these fibers grow for themselves.
3. What is the function of the centrosome (the area) of the centrioles? Is it necessary for mitosis? Justify your answer.
The function of the centrosome to the microtubules and collect their connection to the chromosomes. It is necessary for mitosis, because without them there would be the formation of microtubules, which means that the chromosomes are not separated.
1. If their opinions were not confined to the area of the tip of the rootactively dividing, as the results were different?
In most cases, the cells at the interface. The dividing cells were growing. Most other cells in the root tip and stay at the interface. It would if we were likely looking for another party was at the interface.
2. Based on the data in 3.1, what can we conclude about the relative length of time from one end of the onion root password at any stage of cell division?
Most cells were in the interface so that the interface is the longest stage. The largest group was the prophase, indicating that this phase is the second largest. The other three were close to the number, but varies according to which all steps occur rapidly.
