Which organism has more number of chromosomes?
The maximum numbers of chromosomes is found in a protozoan (Radiolarian Allocantha) where total number of chromosomes are 1600 i.e. 2N = 1600 (Haploid number of chromosomes).
Does the number of chromosomes determine how complex an organism is?
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.
Do large organism have more number of chromosome?
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.
Is a ladder fern a fungi?
No staghorn fern is a type of fern. It is not a fungi.
Do you think There is an upper limit to chromosome number?
Yes.There's a practical limit to the number of chromosomes related to how quickly they can line up in homologous pairs for meiosis in sexually reproducing organisms.There's a practical limit to the number of spindle fibers that you can have in the cell during mitosis.But it's a lot.There's a fern with more than a thousand chromosomes.

Some relatively simple eukaryotes such as the adder's tongue fern may have many more chromosomes than a more-complex eukarytoe such as a mammal what might this suggest about the size and organizatr?
Relatively simple organisms with more chromosomes might have smaller chromosomes containing less DNA. Also, some of the DNA in an organism's chromosomes may not carry information that is actually used by the organism.
How many chromosomes in a grape fern?
They have 19 Chromosomes
Where does the hart's tongue fern live?
The hart's tongue fern lives in a damp (moist) shady place like in a forest.

Is the hart's tongue a fern?
The full name gives it away. Its called the Hart's tongue fern. See the related link for more information.
What has the largest number of chromosomes in the animal kingdom?
Hi, i think OI answered this one.there is a species of fern that has a few thousand base pairs.They believe that number of base pairs in not linked to intelligence or complexity, simply linked to age of evolution (my view on it) so the longer the species has lived and evolved the more basepairs it seems to have.
Is the tongue fern endangered?
Yes, yes it is. : (
