To solve this problem, we need to identify which type of cells do not contain spliceosomes.$\newline \bullet$Spliceosomes are complex molecular machines found in the nucleus of eukaryotic cells. They are responsible for the removal of introns from pre-mRNA, a process known as splicing.$\newline \bullet$Eukaryotic organisms include fungi, animals, and plants, all of which have cells that contain spliceosomes.$\newline \bullet$Bacteria, on the other hand, are prokaryotic organisms. Prokaryotic cells do not have a nucleus and do not contain spliceosomes. Instead, their genes are typically organized without introns, so splicing is not required.$\newline$Therefore, spliceosomes are not found in cells of bacteria.$\newline$The correct option is Option 3: Bacteria.
