The term 'Root Container' can be solved by the 8-letter word 'Follicle'. A follicle is a small, spherical or sac-like structure that contains a single cell or a cluster of cells. It is found in many different organisms, including plants and animals. In plants, follicles are used to store nutrients and water, while in animals they are used to produce hormones and other substances. Follicles are also found in the skin, hair, and nails of humans.
