Answer:
The answer is these modifications allow the mRNA to be recognized by the protein synthesis machinery and protect it from degradation. The 5' cap and poly-A tail added to pre-mRNA complete the transformation to mature mRNA

Animals have centrioles to form spindle fibers during prophase. The centriole divides cells. Plants dont have them because they have microtubules instead. they dont need centrioles. Plants are capable of forming a circular loop of microtubules around the future plane of division prior to prophase called the preprophase band, rather than centrosome. Basically- plants don't need it. They have a different way of cell division.
