What is the conclusion of mitosis in onion root tip lab report?

The conclusion of this lab was that Mitosis is essential for the production of new cells. In the case of the onion root sample, the cells were damaged leading to the tester to undergo Mitotic cell division and it was found that mainly Interphase and Prophase were the stages that occurred in this lab.

What is the hypothesis for the onion root tip lab?

Hypotheses: The experimental hypothesis is that in root tips slices that have been treated with nocodazole, a chemical that interferes with microtubular polymerization, all of the cells will be arrested at the same stage of the cell cycle and that in untreated onion tip slices all of the different stages of the cell ...

What is the observation of onion cell experiment?

Observations. There are a large number of regularly shaped cells lying side by side and each cell has a distinct cell wall. A distinct nucleus is present on the periphery of each cell. Lightly stained cytoplasm is observed in each cell.

What happens at the conclusion of mitosis?

Once mitosis is complete, the entire cell divides in two by way of the process called cytokinesis (Figure 1).

What is the conclusion of onion cell experiment?

Answer: Conclusion. As cell walls and large vacuoles are clearly observed in all the cells, the cells placed for observation are plant cells.

What is the purpose of iodine solution in onion experiment?

The iodine acts as a stain to make the structures in the cell easier to see. Carefully lower a cover slip over the onion skin. Try to avoid trapping air bubbles. Place the slide on the microscope stage.

What is the independent variable in the onion root tip lab?

independent variable: different cells of onion root tips. dependent variable: amount of time in each stage of the cell cycle. operational definition: number of cells in each stage.

What happens in the 5 stages of mitosis?

Prophase – The chromosomes shorten and thicken. Metaphase – Chromosomes line up in the middle of the cell. Anaphase – Chromatids break apart at the centromere and move to opposite poles. Telophase – Two nuclei formed after nuclear envelopes reform around each group of chromosomes.

What are the five 5 stages of mitosis?

Mitosis is conventionally divided into 5 phases, which include prophase, prometaphase, metaphase, anaphase and telophase and cytokinesis.

Why is mitosis important in onion root tip cells?

The reason for onion root tips undergoing mitosis is increasing the number of cells in the root tips, growing the root tip and the root in general. That leads to the plant having a larger root that increase its stability and decreases the possibility of the plant getting uprooted.

What is the observation of mitosis?

There are 5 different stages of mitosis that can be observed namely; interphase, prophase, metaphase, anaphase and telophase. By using certain chemicals to stain the cells, most of the cells can be observed under different stages of mitosis.

What is the procedure to observing cells in root tip?

Cover the root tip with a cover slip and then carefully push down on the cover slide with the wooden end of a dissecting probe. (Push hard, but do not twist or push the cover slide sideways). The root tip should spread out to a diameter of about 0.5- 1cm. Observe it under a compound microscope in 10x objective.

How many chromosomes are in onion root tip?

Onion root tip cells have 16 chromosomes in each cell.

What is the conclusion of onion cell experiment?

Answer: Conclusion. As cell walls and large vacuoles are clearly observed in all the cells, the cells placed for observation are plant cells.

What is the end result of mitosis and why is it important?

The purpose of mitosis is for cell growth and to replace damaged cells. So, the end result of Mitosis is two identical daughter cells.

What happens during mitosis summary?

Mitosis is a process of nuclear division in eukaryotic cells that occurs when a parent cell divides to produce two identical daughter cells. During cell division, mitosis refers specifically to the separation of the duplicated genetic material carried in the nucleus.

How do you describe the result of mitosis?

The result of mitosis is two identical daughter cells, genetically identical to the original cell, all having 2N chromosomes.

What can you conclude about onion cell under microscope?

Onion skin cells seen through the microscope are also transparent. However, they are generally rectangular in shape, with a distinct cell wall. Like all cells, there is also a plasma membrane surrounding the cell contents, but it clings closely to the cell wall and is hard to see with a light microscope.

What is the explanation of an onion cell?

An onion cell is a plant cell that has an outermost rigid cell wall and a large vacuole. They appear brick-like in shape. On the other hand, a human cheek cell is an animal cell having a rounded structure but lacking a cell wall.

Why is mitosis important 3 reasons?

Mitosis is important for three main reasons: development and growth cell replacement and asexual reproduction.

Is mitosis haploid or diploid?

Mitosis produces two diploid (2n) somatic cells that are genetically identical to each other and the original parent cell, whereas meiosis produces four haploid (n) gametes that are genetically unique from each other and the original parent (germ) cell.
