Spinach has a diploid chromosome number of 12, meaning that there are 12 chromosomes in each body cell.
the human body is made primarily of diploid cells
The haploid chromosome number is half the chromosome number of the body cells. For example, in humans, body cells have 46 chromosomes. In human haploid cells (sex cells), there are 23 chromosomes.
All cells in the human body that are not gametes (sperm or egg cells) are diploid. Gametes are haploid.
Theophilus Painter, one of the preeminent cytologists of the early twentieth century, estimated in 1923 that the number was 48. In 1956, improved techniques enabled researchers Joe Hin Tjio and Albert Levan to publish a paper stating that the number was 46. Within a year, Ford and Hamerton provided confirmatory data, reporting the diploid chromosome number in human testicular cells to be 46.

Human body cells that are 2n are called "diploid"
Cells which contain two of each chromosome (two sets of chromosomes) are said to be diploid. In most organisms, the body cells are diploid.

the human body is made primarily of diploid cells
Haploid and diploid are terms which refer to the number of copies of a chromosome that are found in the genome of an organism. In humans, for example, there are two copies of each (of our 23) chromosomes. Thus, we are diploid. If there is only one copy of a chromosome, this is called haploid. Human sex cells as well as most plant sex cells (sperm/ pollen, ovum/ oval) are haploid. This is how you end up with a complement of chromosomes that is half your father's, half your mother's. Two haploid cells come together to form a diploid cell, and this cell eventually becomes a person. Diploid is a full set of chromosomes inherited from both parents. In humans this would be 46 chromosomes, or 23 pairs in, mostly, somatic cells. Haploid is half this number of chromosomes and is the result of meiosis, where as diploid is the result of normal cellular mitosis (as well as the result of fertilization). In genetic notation haploid is depicted with "n" and diploid "2n"
For a cell to be diploid means it has two sets of chromosomes. A cell gets one set of chromosomes from the mother and one set from the father.

every where
Generally, a somatic cell in a human body has 46 chromosomes, which are two complete sets of 23 chromosome pairs. Because they have two sets, these cells have a ploidy level of diploid.
All the cells in the human body are diploid with the exception of germ cells in the testes and ovaries.
