The different components that make up blood. Plasma, white blood cells, red blood cells, platelets.

The chromosome is the one that carries the genetic information. The gene is the basic unit of heredity, meaning, this is the one that we carry from our parents. Genome is the collection of genes that is present in an organism. Therefore, if we arrange this from simplest to the most complex, the arrangement would be GENE, CHROMOSOME, GENOME.
