Propagation simply means reproduction.

  1. adequate air
  2. viable seed
  3. optimum temperature
  4. adequate moisture

SEXUAL PROPAGATION

Sexual propagation involves the union of the pollen (male) with the egg (female) to produce a seed. The seed is made up of three parts: the outer seed coat, which protects the seed; the endosperm, which is a food reserve; and the embryo, which is the young plant itself.
