<span>Prokaryotes have magnetite-containing structures, nucleoid (their version of a nucleus), fimbriae.
Animals have lysosomes.
Plant cells have chloroplasts (make the plant cells green, produce energy for plants), photosynthetic membranes (produce energy for plants), cell well.
Flagella can be found in prokaryotes and animal cells but for a simpler biology class, I would put it with prokaryotes.</span>

Explanation:
Hi Ari. I haven't finished the homework either. And Mr. Bird is out today.
Answer: Exons
Explanation:
In eukaryotic cell the primary transcript are very long the contains coding region (exons) and non coding region (introns)
The parts of the gene sequence that are expressed (coding region) in the protein are called exons, because they are expressed, while the parts of the gene sequence that are not expressed in the protein are called introns, because they come in between the exons.
Intron is a portion of a gene that does not code for amino acids. These Intron sequence are cleaved out and exons are spliced (I. E combine together) to form the mature mRNA molecule.
Exons are the mRNA parts that are kept and used to make protein.
