Abstract –For this lab there is no experiment to be done only questions to be answered. In this experiment we will categorize and count the cells to compute the mitotic index of the total root area.
Introduction – The purpose of this experiment is to answer questions associated with the onion root tip photos that are pictured in the lab. The questions for this lab will be drawn from the discussion and review section at the beginning of the mitosis lab. Once that section has been reviewed we may begin to answer the questions.
Hypothesis-There is no hypothesis for this experiment
Procedure-Review discussion about mitosis, examine the six photos of the mitosis of onion root on the worksheet provided. After this is done, record your results to the questions associated with each photo in the lab report.
Results- To gain knowledge about Mitosis in plants. By reading the discussion and review we were able to answer questions in lab manual about mitosis. The mitotic index in question K was determined to be 5.5 and taken from the stem.
Discussion- The results showed that the further away from the root the less the mitotic index is. From this lab we learned about the different stages of mitosis and how to determine them.
Conclusion-
We answered questions based on the discussion and the six pictures of onion root tip to answer questions about mitosis. We concluded that the further away from the root, the less mitotic index there will be.
Questions-
A. What is the purpose of mitosis? The purpose of mitosis is the process by which the body builds tissue to grow and repair itself. Some organisms also reproduce asexually through
Mitosis and the purpose of it is to create an identical replica of a cell. B. Why is the cell cycle important for organisms? Mitosis duplicates the cells chromosomes by removing the original parent chromosomes and replacing them with newly replicated chromosomes in two exact copies of the
