Online Onion Root Tip Assignment
In this activity, we'll use lab data to test the hypothesis that lectin promotes mitosis in onion roots. The two variables for the activity are Phase and Treatment. Each row in the dataset is an individual cell observed with a microscope. Phase corresponds to whether the onion cells were observed to be in "Interphase" or "Mitosis" and.

These regions of growth are good for studying the cell cycle because at any given time, you can find cells that are undergoing mitosis. In order to examine cells in the tip of an onion root, a thin slice of the root is placed onto a microscope slide and stained so the chromosomes will be visible. The cells you'll be looking at in this activity.

The assignment. In this activity, you will be presented with cells from the tip of an onion root. You will classify each cell based on what phase it is in. At the end you will count up the cells found in each phase and use those numbers to predict how much time a dividing cell spends in each phase. You can base your calculation on a total cell.

This lesson was designed to accompany the Online Onion Root Tip Activity (Arizona--The Biology Project). Students classify diagrams of onion root tip cells into the correct phase of the cell cycle in an interactive and receive feedback in the form of hints for cells they classify incorrectly. Students record their data from the cell cycle interactive in a table and answer questions to measure.

The student will correctly identify and draw four stages of mitosis using microscope slide images of onion root tips and whitefish blastulae. Procedure: The slides below show longitudinal sections of allium (onion) root tip. Because growth in roots occurs at the tips, this is where cells will most actively undergo mitosis. Scroll through the.

Yes, onions can be grown in containers in Arizona. Choose a container that is at least 10-12 inches deep to accommodate the onion's root system. Ensure the container has good drainage and use a well-draining potting mix. Place the container in a sunny location and provide regular watering and fertilization.

Part 2 Directions (if your school has access to onion root tip mitosis microscope slides) Go to the microscopes set up on the tables. Discuss what you see with a partner and determine which phase of the cell cycle each microscope is pointing to. Write the name of each phase of the cell cycle beside each blank.

Mitosis in an Onion - view picture, identify the stages of mitosis in each of the cells. Cell Cycle Label - label a picture of the stages of mitosis, identify parts of the cell such as the centriole and spindle. Onion Root Tip Lab - view real cells with a microscope, requires lab equipment and prepared slides

Plant onions 1 inch deep but no deeper, and at least 4 inches apart. Onions like a lot of water so get them thoroughly wet after planting. Onions roots also aren't deep, so keep the soil at the base slightly damp. Mulching to retain water will help keep onions from drying out.

The neck of the onion needs to dry out completely. The skins will start to change to a uniform color. Once thoroughly dry, cut off the roots and the tops (leaves) to one inch. They are now ready to be stored in a cool place where they get sufficient airflow. Sweet onions do not store as well as other types.

Objectives. Students will be able to outline the events of the cell cycle in order to classify diagrams of onion root tip cells in the correct phase. Students will be able to infer the relative length of time cells spend in each phase of the cell cycle. Directions: Navigate to the website and complete the tutorial followed by the activity.

The second part will be an actual survey of an onion root tip completed in the lab. In this online simulation, you will classify each cell based on what phase it is in (interphase, prophase,. (If you Google 'onion root tip mitosis, University of Arizona' it should be the first to come up.) 2. Read the introduction and then click "next.

biology, developed at The University of Arizona. This interactive activity will answer the question, do all phases of the cell cycle require the same amount of time for completion? The answer can be found by simply counting the number of cells in each phase of mitosis and interphase in an onion root tip. Many cells in a

3. 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 about 0.5 - 1 cm. Observations of onion root tip squash. Scan the microscope under the 10x objective.

Although the chromosomes are organized in this cell, the chromatids have not separated into two separate groups.. University of Arizona Tuesday, January 7, 1997 Revised.
