Describe how surface to volume ratio limits how large a cell can grow.?

The ratio between the surface area and volume of cells and organisms has an enormous impact on their biology. For example, many aquatic microorganisms have increased surface area to increase their drag in the water. This reduces their rate of sink and allows them to remain near the surface with less energy expenditure.\n\nAn increased surface area to volume ratio also means increased exposure to the environment. The many tentacles of jellyfish and anemones are the result of increased surface area for the acquisition of food. Greater surface area allows more of the surrounding water to be sifted for food.\n\nIndividual organs in animals are often based on the principle of greater surface area. The lung is an organ with numerous internal branchings that increase the surface area through which oxygen is passed into the blood and carbon dioxide is released from the blood. The intestine has a finely wrinkled internal surface, increasing the area through which nutrients are absorbed by the body. This is done to increase the surface area in which diffusion of oxygen and carbon dioxide in the lungs and diffusion of nutrients in villi of the small intestine can occur.\n\nCells can get around having a low surface area to volume ratio by being long and thin (nerve cells) or convoluted (villi)\n\nIncreased surface area can also lead to biological problems. More contact with the environment through the surface of a cell or an organ (relative to its volume) increases loss of water and dissolved substances. High surface area to volume ratios also present problems of temperature control in unfavorable environments.

Cells are not all of the same size, but average size is close to 15 micrometers.

That depends on the type of cell and its function.

Since a cell's volume increases significantly more than its surface area as it enlarges, the membrane cannot supply all the requirements of the cytoplasm past a certain point.  This is why cell size is generally limited.  So the function you are referring to is diffusion, the movement of material into/out of the cytoplasm.

It has to undergo mitosis so it can develop more cells.

It has nothing to do with surface area/volume ratio of their cells. Surface area/volume ratio is only a factor when you are talking about single cell species. In multi-cell species, such as bears, humans, ants, elephants, trees,...... it is the number of the cells that determine their size: a baby has a smaller size than an adult human because he has fewer cells not because his cells are smaller than an adult.\nIn case of polar bear vs. black bears size, other than the number of the cells, the amount of fat they have reserved in their body is another factor.

there are different formulas for volume.

the cell dividing force lol. theres no such force. it's a spontaneous occurence

hahahah, really i must say one thing about thsi question , this question relly confused all the guys so far answered it. \nok listne, the dimention is not fixed. when u try to minimize a surface area while keeping the volume constant u tend to form a sphere, think of a ball which can be inflated, when the ball is fully inflated, its totally perfect sphere and then it cant be deformed to anyother shape with ur hands.ths is just tru with sphere and not with cube or anyother shape, other shapes can always be deformed\nso a shape which has its surface area and volume same is never a sphere can thus it can be deformed to any shape keeping its surface area and volume same.\nso the ans to this question is : NO DEFINITE SHAPE

For a specific kind of solid, yes.  In general, no.\n\nFor example, a cube with a side length of s will have a volume of s^3 and a surface area of 6s^2.  So, for any cube, the volume and surface area will be in the ratio of s/6.\n\nFor a right cylinder, the volume is (pi)r^2*h, while the surface area is given by 2(pi)r^2 + 2(pi)r*h, which through some algebraic manipulation can be reduced to 2(r+h)(pi*r).  So the ratio of volume to surface area for a cylinder will be r*h to 2(r+h)... \n\nFor other solids, you could observe similar relationships, but in general, the relationship depends on the shape of the solid, so you could not make a definitive statement about the surface area enclosing a certain volume unless you also knew what shape that volume was in.

Answer = A\n\nA larger cell (answer B) can hold more charged particles, but a small cell with 5 charged particles will have the same potential as a large cell with 5 charged particles!\n\n(C) and (D) relate to how quickly the cell can re-creat the resting membrane potential once, say, an action potential has passed through the nerve.

one cell divides to two cell and the new cells grow in size and the process repeats itself

Some pros\n\nCells with a cell wall are stronger \nCells can withtsand far greater degrees of positive osmotic pressure (higher concentrations of water outside of the cell).\nWhen cells die they can still serve a purpose within the organism by contributing to structural rigidity or fluid transport (e.g. xylum in plants)\n\nSome cons\nCells with cell walls are limited in size by the size of the cell wall\nIn situations of high negative osmotic pressure the cell membrane can detatch from the cell wall and is often ruptured, killing the cell\nCells with cell walls are very rarely able to move unless they have specialist attatchments like flagella

Cells have different shape to allow them to work better. For example, the alveoli cells are flat and big in surface, these features helps in gas exchange.

It divides by mitosis then it begin to grow.According to which type of cell your referring to.That's what I think.
