All organisms have their individual genetic materials in their cells and in the case of the onion cells, it's genetic materials (genes) are stored in the chromosomes hence it is important the cells have these chromosomes.

Answer:
By organising them into five major kingdoms and further dividing each kingdom into phyla (or divisions), classes, orders, families, genus, and species.
Explanation:
There are five kingdoms:
- Monera: bacteria
- Protista: amoeba, paramecium, euglena
- Fungi: yeast, rhizopus
- Plantae: flowering and non-flowering plants
- Animalia: animals (vertebrates and invertebrates)
Organisms that share the most similar features are grouped into the same species. Species with similar features fall under the same genus. Several genus make up a family, several families make up an order, several orders make up a class, several classes make up a phylum (or division), and several phyla (or divisions) make up a kingdom.
Note: there are three domains (or superkingdoms): Archea, Bacteria, and Eukarya.
