Cells are so small so the surface area and volume of them can be proportional to each other. This helps with the efficiency of the cell's absorption and waste expulsion processes. Also by the cell's smallness, communication from the nucleus to other organelles is fast and the cell can be regulated while the conditions for diffusion are still ideal.Cells are small because they need to be able to diffuse through materials easily. Also, materials inside and outside of the cell need to easily pass through the cell membrane, which makes it harder and slower for the materials to pass through the cell membrane
Cells are small because the ratio of surface area to volume is the most efficient at their size. This is because when you have a lot of small objects vs a few big objects the surface area is much larger in relation to volume. Another reason is when the cells are small and plentiful, they are easier to replicate and replace when damaged.
If a cell grows beyond a certain size, materials will not be able to pass through the membrane fast enough to accommodate the inside of the cell. So when the cell reaches a size too large, it will divide into smaller cells in order to maintain a surface area/volume ratio that is more favorable to the functioning of the cell. Therefore, cells remain small in order to survive Cells are so small because they must constantly interact with their surrounding environments. This interaction causes cells to replicate themselves by breaking large molecules into smaller ones which allows for the entire surface area of the cell to be in contact with the environment once again. Environmental contact is vital to cells in order for nutrients and other items to pass through the cell membrane for nourishment. Cells are also so small because it is simply easier to replace them without disrupting the functioning of other cells within the normal environment (ex: human body or plant cells).
Cells are so small because they are easier to replace, and a cell needs to be small to be able to perform the tasks a cell needs to do. If cells were bigger it would be harder for the body to replace the cell without disrupting what is going on in the body and delaying a process. Also since the cells are so small it is easier for them to get the nutrients they need and to get rid of waste.
The reason why cells are small is because they are always interacting with the environment around them. In other words, material is always diffusing in or out of the cell through the plasma membrane. If a cell were to grow larger the internal volume increases, as does the surface area of the cell. However, the volume increases at a faster rate than the surface area. So if the cell reaches a large size it must divide or else it will pop. This is because the surface area isn't large enough to occupy the volume the cell holds.
Cells are so small because if their surface area exceeds the volume, then it would require too much energy to keep the cell functioning. By being so small, they are far more sufficient than they would be if they were larger. This is a similar concept with insects. Most insects reach a point where they don't grow any larger because once they are too big, it takes too much energy to keep their bodies functioning. The smaller the cells, the easier it is to produce energy, and to allow materials to flow into and out of the cell. If cells get too big, they require too much energy and will no longer be able to allow material to flow in or out.
There are a few reasons why cells are so small. The smaller the cell is the faster it can communicate which means that it will be able to diffuse faster and with much less complications. Also since cells are small, they can go through reproduction smaller. Just think if we had large cells to reproduce? That might take much longer. If the cells are small, they also wont destruct as easy due to the tough cell walls around a smaller cell. If a bigger cell had the same cell wall, i think it would be easier to be damaged. So the main point about our cells being small is that they are all around faster and more efficient.
-Cells have such a small size for their own benefit. First they are small in size to allow nutrients and other materials to diffuse through the cell membrane, they keep a small ratio of surface area to volume. Also the size of cells makes them easier to reproduce and replace, as this is a constant process.
Cells are so small because they need to minimize the distance between their nucleus and the other organelles that it must constantly regulate. A smaller cell maximizes the speed that intercellular communications can happen, yet still provides ideal conditions for diffusion. If cells were larger, the distance between their nucleus and organelles would be increased, therefore decreasing the maximum speed of the intercellular communications.
