There is about 1,500 - 1,800 cactus species known.
they don't transport molecules

Answer:
Structural organization of brain and structural correlation within complex neural systems along with easy Signal (electrical or neural) transmission
Explanation:
White matter is a kind of fatty substance known as myelin which surrounds the nerve fibres known as axons. This myelin is commonly found in almost all long nerve fibers and serve the purpose of providing insulation to other body parts from the nerves carrying electrical signals. In this way, a message passes quickly from one place to other. It also organizes the brain structurally and architecturally and also establishes structural correlation within complex neural systems.
After a certain age , the white matter starts wearing and a person faces co-ordinaton issues.
