Part b - comparing eukaryotic and prokaryotic cells two fundamental types of cells are known to exist in nature: prokaryotic cells and eukaryotic cells (like the one shown in the tour of an animal cell animation). both prokaryotic and eukaryotic cells carry out all of the processes necessary for life, but they differ in some important ways. in this activity, you will identify which cell structures are found only in prokaryotic cells, only in eukaryotic cells, or in both types of cells. drag each cell structure to the appropriate bin.

Answer;Prokaryotic only: nucleoid Eukaryotic only: nucleolus, lysosome, mitochondria Both: plasma membrane, ribosomes, flageliaExplanation;Prokaryotic cells are those cells that lack nucleus and other membrane bound organelles, unlike eukaryotic cells which contain a membrane bound nucleus and membrane bound organelles such as mitochondria, and lysosomes.Prokaryotic cells lack the nucleus and nucleolus, but instead contain  a nucleoid which contains the genetic materials of the cell.Eukaryotic cells on the other hand contain a well defined nucleus, that contains nucleolus and highly complex genetic material.Despite the differences, they both share a number of organelles and characteristics such as plasma membrane, which regulates the movement of substances in and out of the cells,  ribosomes, sites for protein synthesis, and also flagella, for locomotion.
