A chromosome is an organized structure of DNA and protein found in cells. It is a single piece of coiled DNA containing many genes, regulatory elements and other nucleotide sequences. Chromosomal DNA encodes most or all of an organism's genetic information; some species also contain plasmids or other extra-chromosomal genetic elements.

Bone ash/bone meal is normally used as an organic fertilizer as it contains calcium and phosphorus which are both nutrients for plants. Bone meal is a mixture of crushed and coarsely ground bones that is used as an organic fertilizer for plants and formerly in animal feed. As a slow-release fertilizer, bone meal is primarily used as a source of phosphorus. This organic fertilizer enables plants to store and transfer energy, promotes root, flower and fruit development, and allows early maturity.
