Respuesta :
As the cube size increases or the cell gets bigger , then the surface area to volume ratio - SA:V ratio decreases. When an object/cell is very small, it has a large surface area to volume ratio, while a large object/ cell has a small surface area to volume ratio.
An increase in the volume of cell beyond its limited surface area will lead to the death of the cell.
Further explanation:
In a cell, the movement of molecules takes place into and out of the cell with the help of the plasma membrane. The waste products are excreted out of the cell while the food material and gases are absorbed by the cell with water. The internal region of the cell is served by the regions of the cell surface. The internal volume of the cell increases as the cell grows in size. This also results in the expansion of the cell membrane.
It is noted that the rate of increase in cell volume is higher than that of the surface area. Therefore, the amount of surface area for the transport of materials into the cell decreases comparatively with the increasing volume as the cell now requires more food in order to survive. The growing needs of the enlarged cell cannot be met by the decreased surface area. Therefore, the cell needs to stop further growth for survival.
As the cell becomes larger, the ratio of surface area to volume goes down. When the cell enlarges far away to a certain limit, the passage of molecules across the membrane cannot match to accommodate the increasing volume. In such cases, the cell either divides or stops its functions. A large number of small cells are formed when the cell divides, each cell having favorable ratio of surface area to volume in order to function properly. While when a cell volume becomes too large, the diffusion pathways involved in the transport of materials through the membrane also becomes long. These diffusion pathways are unable to support the increased volume and eventually, the cell dies.
