Diploid state of organisms is originated during process of fertilization of sexual reproduction. During fertilization, two haploid cells or gametes of different types are fused together to produce a diploid egg (zygote).
Neutral variation and Diploidy.
Diploid is the term for cells that contain two chromosomes of each pair. Euploid is a term meaning normal body cells.
Firstly, some cells (depends on what species you're talking about) have only one copy of each chromosome. Secondly, our opinions on whether haploidy or diploidy is better doesn't have anything to do with reality.
In mitosis, the end result is a DIPLOID chromosome. In meiosis, which is the process of forming new gametes (sperm and egg), the chromosomes split longitudinally at the centromere, resulting in a gamete which is HAPLOID, ie, it only has 50% of the normal number of chromosomes. When the egg and sperm unite, the resulting fertilized egg now has been restored to a diploidy.

The absence of a cell wall in animals allows for increased mobility. Cell walls provide structural support and rigidity, so without them, animals are able to move and change shape more easily. Diploidy refers to having two sets of chromosomes in a cell, which is unrelated to the presence or absence of a cell wall.
