WebThen click Remove Slide and clean the microscope. Hint: You may have to move the slide around to find each phase. 7) In the Slide Catalog, click on the Plant Slides. 8) Click on the Onion Root slide. It will automatically be placed on the stage of the microscope. 9) Follow the steps you learned in the previous lab to view the onion cells using different objectives. WebInterphase cells typically have one or more nucleoli. Prophase. Observe the condensing chromosomes (dark regions) in the cell on the left below in early prophase. Note the cell on the right below with more prominent chromosomes and having lost the nuclear envelope. Metaphase This a very nice metaphase cell.

WebA student treats some onion root tips with colchicine that is responsible for arresting cell division at the metaphase stage (by dissolving spindle fibres) and further prepared a slide of the root tip staining with acetoorcein (stains chromatin) and observed under high power of compound microscope. WebIt is given that the number of chromosomes present in each onion root tip cell is 16. Hence, the number of chromosomes in the cell will be 16 at G 1 phase, after S phase and after M phase. Also, if the DNA content after M phase is 2C. Hence, the DNA content at G …

Hence, mitosis is a process of cell duplication. Meiosis is the kind of cell division that generates our sex cells, and in this, a single cell duplicates itself twice, thus producing four cells.
WebNote: There are four major phases of mitosis, plus prometaphase, which is a transition phase between prophase and metaphase. Step 3: Using the prepared slide, record the number of cells in each phase of the cell cycle. Use the method shown in Figure 13.4 to count the cells.
WebMetaphase (from Ancient Greek μετα-() beyond, above, transcending and from Ancient Greek φάσις (phásis) 'appearance') is a stage of mitosis in the eukaryotic cell cycle in which chromosomes are at their second-most … fancy expensive dining chairsWebB. Metaphase As was the case in plant cells, during metaphase the spindle fiber microtubules become attached to the kinetochore of each centromere region, and the duplicated chromosomes (each consisting of two sister chromatids) line up on the spindle equator.
