Micropropagation is the artificial process of producing plants through tissue or cell culture techniques. It involves taking plant cells or tissues and growing them in an artificial nutrient medium to produce multiple new plants. Methods include taking advantage of apical dominance to induce branching and producing haploid plants from gametes or gamete-like cells that did not undergo fertilization but can still generate a viable individual containing only one set of chromosomes. Haploid plants and dihaploid cells, which contain two copies of the same haploid genome, have applications in plant breeding and genetics.

4. 1. Micropropagation
 is the artificial process of producing plants vegetatively
through tissue culture or cell culture techniques.
 In this artificial process of propagation, plants are
produced invitro by asexual means of reproduction or
by vegetative propagation.
 Methods Involve:

8. Apical dominance means that the growing apex of a plant
controls the quiescence/dormancy of buds sitting in lower
positions along a shoot.

14.  Haploid plants originate from gametes (or gamete-like
cells) that do not go through fertilization, but can still
generate a viable individual.
 Therefore, haploids contain only the chromosome set
found after meiosis in male (sperm cells) or female (egg
cells) gametes (1 set of chromosome; 1n)
 Dihaploidy is the state in which the nucleus contains
two copies of the same haploid genome.
 A cell showing dihaploidy is called a dihaploid.
