The correct answer is (b.) Lateral meristem. Primary growth or lengthening of plants results from a mitotic division in cells of a tissue, lateral meristem. This meristematic tissue are group of cells that has the ability to divide.
The mitotic spindle pulls the chromosomes together at the metaphase plate. Microtubules from opposite spindle poles grab the two sister chromatids of each chromosome. In metaphase, the spindle has collected all the chromosomes and lined them up at the middle of the cell, ready to divide.
<h3>
What are chromosomes?</h3>
Chromosomes are the greatest level of DNA and protein organization. Chromosomes' primary job is to transport DNA and genetic information from parents to offspring. During cell division, chromosomes play a vital role. They keep DNA from becoming twisted or damaged.
The metaphase plate is a plane or region that is about equidistant from a dividing cell's two poles.
