Technically, ginger is a plant with a specialized stem called a rhizome which is a horizontal underground stem that often sends out roots and shoots from its nodes. These roots can develop into stem tubers for storage or root tubers for asexual reproduction.

A flower has calyx, corolla, androecium and gynoecium. Calyx and corolla are accessory organs, while androecium and gynoecium are reproductive organs. Photosynthetic activity is found in the calyx, green shoulder, pericarp, and locular parenchyma. It suggests that all of these tissues have significant roles in CO₂ scavenging and the provision of carbon assimilates.

Butter is an emulsion of water in milk fat. The water constitutes the dispersed phase and the milk fat the continuous phase. As well as fat and water, butter products and dairy spread products contain a range of other milk compounds such as protein, lactose, minerals, vitamins, fat-accompanying substances and, in soured butter, microbially formed metabolites such as lactic acid and aromatic substances.

Most proteins are decomposed to single amino acids in digestion. Digestion typically begins in the stomach when pepsinogen is converted to pepsin by the action of hydrochloric acid, and continued by trypsin and chymotrypsin in the intestine. Before the absorption in the small intestine, most proteins are already reduced to single amino acid or peptides of several amino acids.

Cartilage is a flexible connective tissue found in many areas in the bodies of humans and other animals, including the joints between bones, the rib cage, the ear, the nose, the bronchial tubes and the inter-vertebral discs. It is not as hard and rigid as bone but is stiffer and less flexible than muscle.
