Does the size of an organisms genome relate to the organisms complexity?

There is not a direct relationship. The reason is, much of the DNA in organisms is non-coding, that is, does not contain genes. Non-coding DNA can be duplicated or lost (as can coding DNA), so in theory, a less complex organism can, through duplications of its non-coding DNA, generate a larger overall genome than a more complex organism.

Why do larger organisms not need more chromosomes?
There is no correlation between number of chromosomes and size, nor is there a correlation between number chromosomes or genes and complexity. More chromosomes or genes aren't needed to maintain a larger animal because there is a copy of the genome within each cell.
Human genome fully sequenced?
The human genome, which contains 3.4 billion base pairs, is the largest sequenced to date. The genome of rice (Oryza sativa) is the largest and most complex fully-sequenced plant genome. It contains over 430 million base pairs and an estimated 46,022 to 55,615 genes. [Science 296(5565):79-92] In contrast, the human genome contains an estimated 23,299 genes. Genome size is independent of organismal complexity.
Why is a circulatory system not needed in very small organisms?
Because of their very small size and lack of complexity, diffusion and osmosis are sufficient to supply the whole organism with its needs, and therefore, they do not need a circulatory system
Comparing cells size and shape are related to?
comparing cells size and shape relate to fruction
Does bigger organism have more cells than smaller organism?
No. One of the largest phenomenons in genetics and biology is the C-value paradox: organisms such as flies may have significantly more DNA than animals as large as elephants. There is absolutely no correlation between the size of an animal and the amount of DNA it has in its genome. This is due to varying amounts of repeating and "nonsense" DNA present in any given species' genome. Unless you are talking about the physical size of an organism's DNA, in which case all organisms have DNA made from the same nucleotide subunits which maintain the same size throughout all of creation. What changes is the amount of nucleotides, and therefore the size of the genome.

Why is size and complexity limited in organisms with colonial growth form?
There is no vascular system to bring nutrients up through branches and leaves.

What is coping with complexity in oops?
The size and complexity of a small program is small and simple. Whereas, the size and complexity of a large application program is large and hard. The complexity in dealing with the problems to build a large application depends on the 'composition' and 'abstraction' mechanisms.
What Domain Kingdom have the smallest genome size?
eukaryotes, bacteria
How much DNA is in a gene and how much is in a genome?
Both genes and genomes come in a variety of sizes. About 1,000 base pairs would be enough DNA to encode most proteins. But introns-"extra" or "nonsense" sequences inside genes-make many genes longer than that. Human genes are commonly around 27,000 base pairs long, and some are up to 2 million base pairs. Very simple organisms tend to have relatively small genomes. The smallest genomes, belonging to primitive, single-celled organisms, contain just over half a million base pairs of DNA. But among multicellular species, the size of the genome does not correlate well with the complexity of the organism. The human genome contains 3 billion base pairs of DNA, about the same amount as frogs and sharks. But other genomes are much larger. A newt genome has about 15 billion base pairs of DNA, and a lily genome has almost 100 billion.
