<span>Eukaryotic cells have a nucleus and membrane-bound structures called organelles.</span></span>
<span>Nucleotides are made of a pentode sugar, a phosphate and a nitrogen base. Nucleotides are the building blocks of nucleic acids DNA and RNA which serve as the cell's store house of genetic information. All nucleotides are composed of three parts: a five-carbon sugar, a phosphate and a nitrogen-rich structure called a nitrogenous base. The sugar can be ribose which is found in RNA, or deoxyribose which is found in DNA. The only difference between these two sugars is that deoxyribose has one fewer oxygen atom than ribose.</span>

The taxa under which the given plant fossil come is angiosperm.
<h3>What are taxa?</h3>
Taxa refer to any unit employed in the discipline of biological classification, often known as taxonomy. Taxa are organized in a hierarchical order, from kingdom to subspecies, with a particular taxon typically containing numerous taxa of lower rank.
Taxa are given formal names after being properly identified by nomenclature codes and systems. Bryophyta, Pteridophyta, Gymnosperms, and Angiosperms are a few examples of major plant taxa.
Therefore, the taxonomic group from which the presented plant fossil is derived is angiosperm.
