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.
Yes as the size of animal increase the no. of cells will also increase except in some unicellular organism in which one organism can be bigger then other but both having same no. i.e. unit cell
While if we're talking about microorganisms this isn't always true (some single celled organisms are far bigger than others) at the multicellular level this is absolutely true. Bigger organisms have more cells. This is because there is an upper size limit to cells before they become unable to acquire nutrients through diffusion. Cells really can't be much larger than they are in most multicellular organisms. Therefore, if there's an organism is larger, it isn't because it's cells are bigger but because they have more cells.
Usually yes. Initially (just after conception) it makes more cells as it get smaller - but that's just temporary.
Cells have a correct size, they do not grow bigger or smaller. Growth hormone causes the development of new cells. You get more cells, rather than bigger cells.
It takes less cells to do the job. If you cut yourself, then your body can send less cells to heal the wound compared to when the cells are smaller. You need more cells when you are smaller then when you have the larger cells.
Adding more cells
The cells of an organism carry out the functions it needs to live. Healthier cells carry out the functions more efficiently making it easier for the organism to live aka making the organism healthier
Usually yes. Initially (just after conception) it makes more cells as it get smaller - but that's just temporary.
Because all cells are roughly the same size. This means that bigger animals are made of more cells than smaller animals. (If bigger animals had the same number of cells as smaller animals then the cells they were made of would have to be bigger in proportion to those that smaller animals were made of - and they are not)
Bigger animals are bigger because they have more cells not bigger cells. You would think that this would be so, but cells can only function up to a certain size. So, no, they are not.
More than one. The way of looking at it that most cells are the same size and therefore the bigger the multi cellular organism, the more cells there are in its makeup.

The lion simply has more cells in its body; they're not any bigger or smaller.
A larger dog may have MORE cells than a smaller dog but they are not bigger.
Although weight and mass make organisms differ from each other, it is the number of cells the organism has that makes it its size. Likewise, the more cells the organism has, the bigger it is. The number of cells, not the size of the cells, determine the weight and mass the organism has. Example: An elephant is obviously much bigger than a bear, but due to the fact that it is composed of a greater number of cells.
Girrafe is an eukaryotic organism while bacteria is procaryotic. As we know that eukaryotic organism has larger cells than prokaryotic organism so girrafe has larger cells than a bacterium.
To answer this question as it is written: not necessarily. An organism (bacterium) can be smaller than tissue (the cartilage in my ears). By definition, an organism is more COMPLEX than a tissue, but not necessarily bigger.
