Organisms that have more than two complete sets of chromosomes are said to be polyploid. This often occurs in plants.

Not necessarily. While many members of the same species may have the same number of chromosomes, it does not guarantee that two organisms with the same number of chromosomes are of the same species. Chromosome number is just one characteristic used to define species, but other factors like genetic makeup, morphology, and ability to reproduce with one another are also important in determining species classification.
The common lilac (Syringa vulgaris) has 46 chromosomes, like most plants and animals with a double set of chromosomes for their species.
Polyploid speciation occurs when two different species interbreed, resulting in a hybrid offspring with an extra set of chromosomes. This extra set of chromosomes can come from one or both parent species. The hybrid offspring may then undergo genome duplication, resulting in a new species that is polyploid. This process can lead to the formation of a new species with a different number of chromosomes than either parent species.
Mold can have varying numbers of chromosomes depending on the species. Typically, molds have a haploid chromosome number, which means they have one set of chromosomes. This can range from 1 to several dozen chromosomes.

A polyploid organism has more than two complete sets of chromosomes. The number of chromosomes in a polyploid can vary widely depending on the species and type of polyploidy; for example, a triploid has three sets (3n), a tetraploid has four sets (4n), and so on. Therefore, the total number of chromosomes in a polyploid is a multiple of the basic chromosome set of that species.
Aneuploidy refers to an abnormal number of chromosomes in a cell, typically due to errors in cell division. The correct number of chromosomes in a species is known as euploidy, where cells have a normal set of chromosomes.
An autoploid is a cell with multiple copies of a set of haploid chromosomes from a single parent.
