DNA is found in the nucleus of the cell, and when the cell is small, the information stored in that DNA is able to meet all of the cells needs. But as a cell increases in size, it usually does not make extra copies of DNA. Just think about a small town library with a few thousand books. If the town gets larger, there will be more and more people borrowing books, just like in a cell.
-
Efficient nutrient and waste exchange: Small cells have a high surface area to volume ratio, allowing for quicker exchange of nutrients, gases, and waste products with their surroundings.
-
Rapid response times: Small cells can more quickly respond to changes in their environment due to the shorter distances for intracellular transport and signal transduction.
-
More efficient metabolism: Small cells can generate energy more efficiently as nutrients can readily diffuse into the cell and waste products can be removed more rapidly.
It could be any of these reasons:
1) Cells are small to keep the surface area to volume ratio high. This will allow for
efficient transport of nutrients into - and wastes out of - the cell.
2) The small size of cells enables rapid communication between cells. Such
communication may be in the form of electrical or chemical signals.
3) A small cell can replicate faster than a large one. Replicating to repair damaged
cells is essential to an organism's survival.

* Not all cells are 'small' - an ostrich egg may be 6 inches across, and is a single cell.
Cell size depends on surface area to volume ratio. Being small means that there is a low volume, and a large surface area. This means that heat can be lost easily (a good thing, as respiration produces heat as a waste product), and materials can be exchanged efficiently.
Cells are small to keep the surface area to volume ratio high. The small size of cells enables rapid communication between cells. - See more at: http://www.chacha.com/question/what-are-two-reasons-why-cells-must-be-so-small#sthash.R7HBRmYU.dpuf

Which two examples of dead cells?
Skin cells that have sloughed off and hair cells that have fallen out are examples of dead cells.
What are some examples cells divide rapidly some not at all after maturity?
Examples of cells that divide rapidly after maturity include skin cells, intestinal cells, and blood cells. Examples of cells that do not divide at all after maturity include neurons and cardiac muscle cells.
What are the examples of stable cells?
Examples of stable cells include neurons, muscle cells, and adipocytes. These cells do not typically divide frequently and have specialized functions in the body.
What are the small parts of cells called?
The small parts of cells are called organelles. These specialized structures within cells perform specific functions that are essential for the cell's survival and activity. Examples of organelles include the nucleus, mitochondria, and chloroplasts.
What are some examples of differentiated cells?
Examples of differentiated cells include red blood cells, nerve cells (neurons), muscle cells, skin cells, and liver cells. Each of these cell types has specific structures and functions that allow them to carry out their specialized roles in the body.

What are the examples of eukaryotics cells?
There many examples of eukaryotic cells. All human cells are eukaryotic therefore any cell from our bodies can be an example, like hepatocytes (liver cells).
What is a small one celled organism called?
A small one-celled organism is called a microorganism or a single-celled organism. Examples include bacteria, archaea, and some protists.
Examples of specialized animal cells?
Examples of specialized animal cells include red blood cells, which are specialized for carrying oxygen, and muscle cells, which are specialized for contraction and movement. Other examples include nerve cells (neurons) which are specialized for transmitting electrical impulses, and sperm cells which are specialized for fertilization.
Blood muscle and bone cells are examples of?
It is specialized cells
What are some examples of differentiated cells?
Examples of differentiated cells include red blood cells, nerve cells (neurons), muscle cells, skin cells, and liver cells. Each of these cell types has specific structures and functions that allow them to carry out their specialized roles in the body.
Heart and muscle cells are examples of?
organs and tisues!!-- The answer is somatic cells.
How small are cells?
very small
