What is the result of mitosis in onion root tip?

Unlike meiosis, which is also a type of cell division, mitosis results in the production of two diploid daughter cells. The two daughter cells contain the same number of chromosomes as the parent cell.

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 conclusion of onion cell lab report?

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

Which answer gives the correct sequence of events in the mitosis of onion root tip cells?

The correct option is Condensation → Nuclear membrane disassembly → Arrangement at equator → Centromere division → Segregation → Telophase.

What is the conclusion of mitosis?

Conclusion. Mitosis is the process of nuclear division, which occurs just prior to cell division, or cytokinesis. During this multistep process, cell chromosomes condense and the spindle assembles.

How many chromosomes are in onion root tip?

Onion root tip cells have 16 chromosomes in each cell.

What is the aim of onion cell experiment?

Activity: Observing Onion Cells. Goal: To observe, identify and describe the basic organelles of a non-green plant cell. Background Information: All living things are made up of small units called cells. That is, cells are the basic building blocks of living things just as atoms are the basic building blocks of matter.

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 is a good conclusion for a lab report?

When writing a conclusion you should: briefly restate the purpose of the experiment (i.e. the question it was seeking to answer) identify the main findings (i.e. the answer to the research question) note the main limitations that are relevant to the interpretation of the results.

What goes in the conclusion of a lab report?

Conclusion. Your conclusion should be the final section of your lab report. Here, you'll summarize the findings of your experiment, with a brief overview of the strengths and limitations, and implications of your study for further research.

Where does mitosis occur in the root tip?

The root tip of a plant contains an apical meristem that facilitates the growth in length of the root. The apical meristem is just a small area at the end of the root tip where mitosis occurs (see Figure 1).

Does meiosis occur in onion root tip?

Answer and Explanation: The cells of an onion root tip can only undergo mitosis and not meiosis.

What happens during interphase in an onion root tip?

Interphase. The cell is engaged in metabolic activity and performing its duty as part of a tissue. The DNA duplicates during interphase to prepare for mitosis (the next four phases that lead up to and include nuclear division).

What is the function of an onion root tip?

Onion Root Tips

The root tip of a plant is responsible for a plant's growth downward into the soil. Cells are therefore actively dividing and/or elongating, which makes root tips excellent observation points for mitosis.

Which phase of mitosis is most common in the root tip?

Even in a growing root tip, the majority of the cells will likely be in interphase. In interphase they will look like 'normal' plant cells, with a dark and well defined nucleus . Remember that although interphase is the phase cells spend the most time in, they are not inactive.

Why does mitosis occur more in root tips?

There likely will be more mitotic division in an onion root tip than in other areas of the plant because plant roots grow from the tip of the root. Plant roots grow continuously as they search for water and nutrients, and this growth requires new cells to be rapidly produced.

Are root tip cells haploid or diploid?

Hint: Aleurone layer is a single layer of cells that forms the outermost layer of the endosperm which is triploid and the cells on the root tip are diploid.
