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.
You can get a microscope and get a pice of your organism and see the size of the cells and compare it to the size of another organism, say a plant cell.
The number of cells gets larger, and the organism gets bigger
The number of cells gets larger, and the organism gets bigger
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 simplest test would involve comparing the size of cells in two different organisms of varying sizes under a microscope. This would involve calculating the average size of cells in each organism and comparing the results. If consistently larger cells are found in the larger organism, it would support the hypothesis that bigger organisms have bigger cells.
organ is bigger
A universe is bigger than an organism.
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.
There are many reasons why cells divide. Here are some of them:* Growth - More cells=bigger organism * Repair - Colon and skin cells, for example, have to be constantly replaced as they are scraped off

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.
Cells are much bigger.
