The correct answer to the question above is cytoskeleton. Microtubules, microfilaments, and intermediate filaments make up the cytoskeleton, which lies beneath the plasma membrane and provides support, movement, and shape for the cell. These structures definitely form cytoskeleton for the support and structure.
It also plays a key role in shaping organic molecules. Carbon<span> is very </span>important<span> to the chemistry of living things, mainly because of the versatility of structures it can form with itself and with other atoms</span>
Anaphase I begins when the two chromosomes of each bivalent (tetrad) separate and start moving toward opposite poles of the cell as a result of the action of the spindle. Notice that in anaphase I the sister chromatids remain attached at their centromeres and move together toward the poles.

Excretion<span> is the process of elimination of waste materials from the body. </span>Excretion<span>in </span>plants<span> is much simpler than that of animals and as such it </span>does not pose<span> any serious </span>problem in plants<span>. ... </span>Plants<span> use much of the waste products of catabolism in their anabolic process.</span>
