polyploid
Organisms with three or more sets of chromosomes are called polyploids. Polyploidy can occur naturally or be induced in plants and some animals. It can lead to changes in gene expression and potentially new traits.
Larger organisms do not necessarily need more chromosomes because the number of chromosomes is not directly related to the size of an organism. The number of chromosomes can vary widely among different species, and even among organisms within the same species, without impacting their size. The size and complexity of an organism are influenced by various factors, such as gene regulation and developmental processes, rather than simply the number of chromosomes.
No there isn't. Humans are much more complex than a fern, yet the Adder's Tongue Fern has 1262 chromosomes and a human has only 46. It also doesn't work the other way either (more complex organisms having less chromosomes) for fruit flies have 8 chromosomes and dogs have 78. Also, chimpanzees have the same number of chromosomes as potatoes and, surely, they are on different complexity levels.
A gamete with more than one complete set of chromosomes is called a polyploid gamete. This may occur due to errors in cell division, resulting in an extra set of chromosomes. Polyploid gametes often lead to genetic abnormalities in offspring if fertilized.
Not necessarily. An onion has around 12 times as much DNA as we do, but they are certainly not more complex than we are. Although it is true, "onions have layers." But so do we. Scientists have been perplexed by this question for a while, but some Harvard research has suggested that not all DNA is functional -- some is "junk DNA." And some species dispose of their junk DNA, while others continue to replicate it. This could explain why seemingly simple species have a higher number of chromosomes -- they are simply hoarding their useless DNA.

Chromosomes contain the genes or the DNA of all organisms. Being more complex, does not mean that you have more chromosomes, for example: a human being has 48 chromosomes while chickens and dogs both have 78.
Not necessarily. The number of chromosomes does not correlate directly with an organism's ability to reproduce. Organisms with different numbers of chromosomes have evolved various mechanisms to reproduce successfully, and factors like genetic diversity and adaptability are more important for reproductive success than just the number of chromosomes.
No
More complex eukaryotes do not necessarily have more chromosomes than simpler eukaryotes do. An example from the Holt Science book is that fruit flies have 8 chromosomes, potatoes have 48, and humans have 46. The human cells are more complex, but they don't have quite as many chromosomes as potatoes!
No - haploid cells contain half the normal amount of chromosomes.Polyploid is the term used for a cell/organism with more than 2 sets of chromosomes.
In all living organisms there is a nucleic acid known as Deoxyribonucleic acid. in this DNA are chromosomes. protecting the ends of these chromosomes are small caps called telomeres. these protect the cells from deteriorating but lack the ability to keep themselves from decaying; therefore, in some organisms, these telomeres are more efficient and keep those macromolecules lasting longer than in other organisms.
They are called multicellular organisms.
Organisms can have two copies of each chromosome, one from each parent. This is known as diploid. Other organisms, like plants, can have more than two copies of each chromosome (polyploidy). Having multiple copies of chromosomes can affect gene expression and traits in organisms.
There are more classes of organisms, since it is the most specific of the three.

Polyploidy occurs in cells and organisms when there are more than two paired sets of chromosomes.
