Question

The larger chromosomes get arranged, in which region of the metaphase plate?
A. Peripheral region
B. Variable from plant to plant
C. Central region
D. Not constant

Answer 1

At the cellular level, cell division is the driving force of reproduction. Except for germ cells, which have half the number of chromosomes, most eukaryotic cells divide in a way that keeps the ploidy or number of chromosomes the same.

Complete answer:
Mitosis is the phase of the cell cycle in which a cell's nucleus is split into two nuclei, each with an equal quantity of genetic material. After the nucleus has been separated, it follows the G2 phase and is followed by cytoplasmic division.
Mitosis is required for cell development and the replacement of worn-out cells. Abnormalities in mitosis can cause genetic diseases by altering the DNA.
Mitosis Characteristics:
Each cell division cycle produces two daughter cells from the parent cell.
The cell is also known as equational cell division since the parent and daughter cells have the same chromosomal number.
Mitosis causes the vegetative portions of the plant, such as the root tip and stem tip, to grow.
This procedure does not include segregation or combining.
The processes that take place during mitosis have been classified into phases.
Interphase
Prophase
Prometaphase
Metaphase
Anaphase
Telophase
During the metaphase stage, the chromosomes are the shortest, most tightly coiled, and most visible. All of the chromosomes are placed on the equatorial plate during metaphase. According to studies, the bigger chromosomes are generally found on the metaphase plate's periphery, whereas the smaller chromosomes are found in the center. This might be because bigger chromosomes travel more slowly than smaller chromosomes, and the distance between the polar centriole and the perimeter of the curved metaphase plate is less than the distance between the polar centriole and the center of the metaphase plate.

As a result, option A is the right answer.

Note:
Significance of Mitosis-
Mitosis is responsible for the zygote's transformation into an adult.
Each daughter cell receives an equal number of chromosomes.
It is in charge of an individual's growth and development.
It ensures that all of an organism's body cells have the same amount of chromosomes.
Mitosis is necessary for asexual reproduction, vegetative propagation, and the repair and regeneration of damaged tissues in plants.
Mitosis helps to keep the genome pure by preventing recombination and crossover.
It is in charge of repairing and regenerating old and damaged cells in animals, such as the gut epithelium, blood cells, and so on.
