A person should know the effect of auxins as it helps in growth of the stems and the person should know how much he should cut otherwise will keep cutting it non uniformly affecting the plant growth and exposure to sunlight.
The apical bud produces the hormone, Indole Acetic Acid (IAA) which is also known as auxin. This chemical is produced in the rapidly growing apical bud and is transported down the shoot. Along the way, the IAA passes the lateral buds and the presence of the auxin keeps those lateral buds dormant. Dormancy means that the buds are "sleeping" or "inactive"; there is great potential for growth of the lateral buds but as long as the apical bud is intact, they remain dormant.
Developing a coelom made nutrients more easily absorbed by roundworms. A coelom is a fluid filled cavity developed in the mesoderm and it is the main body of a roundworm. It contains the digestive tract and many other organs.
