Why is it relatively easy to study mitosis by looking at the roots of a plant under the microscope?
Mitosis is just the cell’s nucleus dividing into 2 separate nuclei, not the cell. … These plants are selected because whitefish blastula and onion root tip have cells that rapidly divide, making it easier to see the different stags of mitosis under a microscope.
Which of these is the special area in the onion root where mitosis occurs?
11 Cards in this Set
|What are the main spots in these onion root tips?||Region of cell elongation Region of cell division Root cap|
|What kind of cell is this in mitosis and what does it do (what happens)??||Metaphase, the chromosomes meet in the middle, you can see DNA lined in the middle of the cell|
Why would we choose an embryonic mass of cells in which to study the stages of mitosis?
Why would we choose an embryonic mass of cells for studying the stages of mitosis? Embryonic mass cells are in constant division, making it much easier to find good examples of each phase of mitosis.
What is stained in red onion root?
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.
Why do we use root tips to observe mitosis?
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. … Hence, their root tips are used.
Why are root tips excellent observation points for mitosis?
The root tip of a plant contains actively dividing cells, making root tips excellent observation points for mitosis. Each plant cell is surrounded by a cell wall, making the identification of cells easy. Also, the cells near the root tip are highly organized into concentric layers, making them easy to see and count.
What are the basics of sperm structure and how does it relate to function?
The head contains the genetic material for fertilisation in a haploid nucleus. The acrosome in the head contains enzymes so that a sperm can penetrate an egg. The middle piece is packed with mitochondria to release energy needed to swim and fertilise the egg. The tail enables the sperm to swim.
Why are they more accurately called cellular replication?
a. Mitosis and cytokinesis are often referred to collectively as “cellular division.” Why are they more accurately called cellular replication? … The result of mitosis is production of two cells (replicates) identical to the parent cell. The genetic material is replicated rather than divided.
