These groupings are called domains.
<span>A domain is the highest taxonomic rank of organisms. Carl Woese, an American microbiologist, and biophysicist designed the three-domain system which describes that the tree of life consists of three domains: Archaea, Bacteria, and Eukarya. Each of these three domains of life is characterized by rRNA which is unique to them.</span>
A nucleus is primarily responsible for directing all processes and reactions in a plant cell. <span>The function of the </span>nucleus<span> in the </span>plant cell<span> is to store the </span>plant's<span> DNA and control the activity of the </span>cell <span>through protein synthesis. The </span>nucleus<span> is enclosed by the </span>nuclear membrane<span>, which has pores for the passage of RNA and proteins. </span>
