Root tip cell in each stage
WebThe onion root tip is an area of active growth and, therefore, one would expect that mitosis is occurring at a rapid rate. What the mitotic index will do is to tell us how active this tissue is. Using a slide of the onion root tip, count 100 cells and indicate which stage of mitosis each of these cells are in. Enter your data in the following ... WebAug 26, 2024 · Each onion root tip cell has 16 chromosomes by default. As a result, the cell will have 16 chromosomes in the G1 phase, after the S phase and the M phase. In addition, if the DNA content is 2C after the M phase, the procedure is complete. As a result, DNA content will be 2C during the G1 phase.
