Why do larger organisms have the same sized cells as smaller organisms?

Regardless the size of an organism, whether only a few cell layers thick or comprised of many trillions of cells like ourselves, the maximum possible size or volume of a cell is very limited. Cells depend upon the free diffusion of nutrients in and out of their cell membrane. As a cell grows larger, its level of surface area to volume decreases and it becomes more difficult to effectively transport nutrients sufficient for their size across the membrane. They are also limited by the relative strength of the cell wall or cell membrane. The greater a cell's volume, the more pressure is being exerted on the membrane and if the pressure were to become too high, the cell would burst. As a result of these physical limitations, cells of any respective tissure are generally the same size accross species.

∙ 13y agoCells are most efficient at a certain size. If they become too large, there is not enough surface area to take in all the necessary materials for the cell to function. If the cell is too small, they can take in more materials than necessary, which allows them to grow.
A cell can grows only as much as it can with the materials it can absorb, and the most efficient size is generally the same despite the organism.

What is bianarry fission?
Binary fission is a method of asexual reproduction in which an organism splits into two. It is found in bacteria and other single-celled organisms eg protozoa.
Do shorter people or dwarfs have the same length intestine as average sized people?
That is a hilarious question-thx,you made my day. It's actually a good one though. I would guess they do. But mabe not, as the smaller mammels have the smaller small intestins, and a COW'S-well you can just imagine!
Why do cells divide and not just get bigger?
because they are at the relatively perfect size for being efficient. any bigger and they would create more waste and need more nutrients, any smaller and it would cause their organelles to be inefficient. and they do get bigger in order to divide but only 2x as big to create to normal sized cells. this doesnt effect the cell because all of its organelles are duplicated as well
Many fungi have multinucleate cells?
The fungi called slime molds do and some other fungi do in certain stages of their life/reproductive cycle. But no, most fungi like other organisms have normal sized cells with only one nuclius.
Which fruit can you produce the most DNA?
A larger fruit (say, a cantaloupe) will naturally contain more DNA than a smaller one (example: a small grape). However, I am sure that this method would not work for similar sized fruits, or for fruits of varying sizes that are cut to be the same mass. For that, you would have to factor in what part of the fruit it came from, and then actually do a DNA extraction experiment which, albeit sounds fun, is too time consuming for me
What test can prove that bigger organisms have bigger cells?
microscope, though you will find that this is not true. a larger animal will still have cells of roughly the same size as smaller or differently sized animals.
What is the weight of average sized Pomeranian?
The weight of an average sized Pomeranian is about 4 pounds. Generally, there are some that are larger and there are some that are smaller, but this is the average.
Is the earth larger or smaller than the averaged sized star?
Earth is smaller than even the smallest star, not counting dead stellar remnants.
Is the Earth larger or smaller than the average sized star?
Earth is smaller than even the smallest star, not counting dead stellar remnants.
What are the small organisms and large organisms?
Small sized animals need less food as compared to large sized animals. A field of plants can support more numbers of small animals as compared to large sized animals which need more food, it is why smaller animals are numerous .
Do thin wires have smaller electrons and large wires have larger sized electrons?
No. Electrons are all the same size
What is the middle-sized continent?
Either South America (18 million km2) or Antarctica (14 million km2) might be considered "medium sized."Australia and Europe are smaller, North America and Africa are larger, and Asia is much larger.
Are the stars larger than the sun?
First things first, the sun is a star, and it is a medium sized star. Some stars are larger than the sun, and some are smaller.
What is the difference between a mustang and a shelby mustang?
A Shelby mustang has a larger sized motor and the original ford mustang has a smaller motor.
Is sleet bigger than hail?
No. Sleet consists of small pellets of ice typically pea sized or smaller. Pea sized hail is common, but in some instances hail can be larger than softballs.
Why does smaller area generate increased pressure even with the same sized force?
Pressure is defined as force divided by area. If you divide by a smaller number, you get a larger result. Try it out with some numbers.
During cleavage furrow why do the cells get smaller?
Cleavage furrow, which is what is shown during cytokinesis, "makes the cell smaller" because it is dividing it in two. During interphase, the cell had to enlarge its size by almost double, and cytokineses divides it into normal sized cells.
