How mitosis can be viewed in an onion root?
Cell division occurs rapidly in growing root tips of sprouting seeds or bulbs. … The super coiled chromosomes during different stages of mitosis present in the onion root tip cells can be visualized by treating with DNA specific stains, like Feulgen stain and Acetocarmine stain.
Why is mitosis observed in onion root tip?
Why is onion root tip used to demonstrate mitosis in this experiment? It is because of the meristematic cells that are situated in the tip of the roots that render the most desirable and suitable raw material to study the different stages of mitosis. Onion is a monocot plant.
What are the 4 stages of the cell cycle?
In eukaryotes, the cell cycle consists of four discrete phases: G1, S, G2, and M. The S or synthesis phase is when DNA replication occurs, and the M or mitosis phase is when the cell actually divides. The other two phases — G1 and G2, the so-called gap phases — are less dramatic but equally important.
Are the different stages of mitosis in an onion root cell division?
Prophase (divided into prophase and prometaphase) Metaphase. Anaphase. Telophase.
What is mitosis and list the stages?
Mitosis has four stages: prophase, metaphase, anaphase, and telophase. Encyclopædia Britannica, Inc. mitosis, a process of cell duplication, or reproduction, during which one cell gives rise to two genetically identical daughter cells.
In which stage were most of the onion root tip cells how would you explain this finding?
The cells cycle stage that most of the cells were in was interphase. To me, this implies that the cells in the onion root tips typically spend a good amount (if not all) of their life span in the interphase stage.
