Reseаrchers оbserved selected internаl structures оf fоur different microscopic orgаnisms as part of a larger study on the divergence between eukaryotes and prokaryotes. Their observations are recorded in Figure 1. Organism 1 contains only one circular chromosome. Organism 2 contains a nucleus with three linear chromosomes and one mitochondrion. Organism 3 contains one chloroplast, a nucleus with three linear chromosomes and one mitochondrion. Organism 4 contains only three linear chromosomes. Figure 1.
