Solved . Use the image of an onion root tip to answer
This lesson was designed to accompany the Online Onion Root Tip Activity. 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 student learning.

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.

Online Onion Root Tips Determining time spent in different phases of the cell cycle. In anaphase, the sister chromatids separate and migrate to opposite poles of the cell. 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.

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.

An onion has a total of 8 pairs of chromosomes. This is especially beneficial for this experiment given that fewer chromosomes are slightly easier to see when they condense. As mentioned, onion root tip cells divide rapidly as the roots elongate to absorb water and various minerals from the soil.

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.

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.

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.

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.

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 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.

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
