Eukaryotic and prokaryotic cells can be compared to mini-factories, with multiple organelles working together to perform numerous cellular processes. After reviewing the parts of a eukaryotic or prokaryotic cell: Choose the organelle that you think is the most important for the cell and justify your selection, describing several key activities this organelle performs. Indicate whether the organelle is in eukaryotic cells, prokaryotic cells, or both. Which organelle do you think is the least important? Why do you think it is more “expendable” to the cell


               The most important organelle in the cell is the nucleus. The organelle contains all the genetic material of the cell, also known as the DNA. The DNA is in charge of directing all the activities that the cell will conduct throughout its life. The nucleus controls the activities of the cell including metabolism and growth. The nucleus does this by using the coding information contained in the DNA, which is placed at the center of the nucleus, the nucleolus. The nucleolus also synthesizes the ribonucleic acid (RNA), which transcripts the DNA’s orders to the rest of the cell. The RNA also passes messages between the DNA and ribosomes. The ribosomes uses the instructions provided to synthesize a multitude of different proteins essential for the proper functioning of the cells. The nucleus is found in all eukaryotic cells.

           The most expendable organelle in the cell is the vacuole especially in animal cells. The vacuole is used for storage in both plant and animal cells. Animal cells have a small vacuole but this organelle is bigger in plant cells. In plant cells, the vacuole stores water that will be needed by the cell during photosynthesis.
