What two things limit the size of a cell?
2 things: Surface Area and Volume Surface: how much surface area (on the plasma membrane) determines how much nutrients the cell obtains, thus controlling how much the cell can grow. Volume: as the cell grows, the volume increases, and the cell's function stability decreases, thus weakening the cell and hindering the cells growth.
Why are most cells small?
The surface area to volume ratio of a cell is important in order to pass materials the cell needs to survive across its surface. There is therefore an optimal size for a cell where it is large enough to hold all its internal structures and yet small enough for cross membrane transport. Any bigger than this and the cell will not be able to get enough nutrients into itself to live and function properly. Thus most cells are of this size (there are specific exceptions). ======================= There is a reason why cells are so small. Cells take in food and get rid of wastes through their outer surface. They need to have a large ratio of surface area to volume. Cells also don't have enough organelles to get the food through out the whole cell. ======================= They need to have a large ratio of surface area to volume ======================= Cells are small because they take in food and remove wastes through it's membrane(skin), so if it's surface area cannot take in enough food for it's volume, the cell can starve/poisen itself, which is why cells cannot be very big. (as an object gets bigger, so does it's volume and surface area. However, volume grows much faster, and if the object gets too big, the volume will exceed the surface area) ======================== The reason why cells must be so small is because cells need enough surface area to export and import all that they need. If they were too big they would not be able to carry out all the things that they do. ======================== Cells need to be small in order to have good surface area to volume ratios. It is important that the surface area be larger than the volume so that the things that need to get in and out of the cell can do so. Otherwise the cell could be poisoned by accumulation of waste or not being able to take in what it needs.
Outer surface of the cell that helps maintain the cells internal environment?
no the outer surface of animal cells are called the cell membrane, plat cells also have a cell membrane but they sometimes also have a cell wall, animal cells don't have cell walls.
What is a limiting factor to cell size?
the ration of volume to cell surface is the biggest factor. if it gets too big, it will take too long to transport necessary molecules form the cytoplasmic mebrane or nucleus out to the environmment or vica versa. size is usually regulated by genes encoded in the DNA.
Where in the cell can you find the cell membrane?
The Plasma Membrane (also known as Cell Surface Membrane) is found in cells of plants and animals.
The area of a cells outer surface in relationship to its volume is?
cell membrane
Why are groups of a small cells better than one large cell at moving material in and out?
they have a greater surface-to-volume ratio
What happens to a cells surface area to volume ratio as it gets smaller?
It increases.
What happens to the relationship between the surface area and volume of the cell as it gets larger?
if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume. When this happens, the cell must divide into smaller cells with favorable surface area/volume ratios, or cease to function. That is why cells are so small. That may be the effect but the question as worded is purely arithmetical. Surface area is proportional to the square of the linear dimensions; volume to the cube.
What happens to a cell ratio of surface area to volume as the cells volume increases rapidly than its surface area?
The cell's ratio of surface area to volume would decrease if its volume increases more rapidly than its surface area.
What are surface cells?
Surface cells are membrane reactors. They store water and serve as integral membrane proteins. These cells bind other cells to each other.
What happens to a cell ratio of surface area to volume as the cells volume increases more rapidly than its surface are?
The cell's ratio of surface area to volume would decrease. However, this scenario is extremely unlikely.
What controls the movement in and out of the cell in plant cells?
cell membrane aka plasma membrane
Why do cells get so big than divide?
Cells are dependent on the ration between surface area and volume. as the cels get bigger the ratio decreases, meaning that the volume gets larger faster than does the surface area. they cant survive past a certain point, because the nutrients that permeate the membrane have a harder time diffusing throughout a larger volume with a comparatively smaller surface area. this is why cells divide: the volume splits in half, but the surface area stays the same.
What does a cell's surface area to volume ratio effect?
As a cell grows bigger, its internal volume enlarges and the cell membrane expands. Unfortunately, the volume increases more rapidly than does the surface area, and so the relative amount of surface area available to pass materials to a unit volume of the cell steadily decreases.Finally, at some point, there is just enough surface available to service all the interior; if it is to survive, the cell must stop growing.The important point is that the surface area to the volume ratio gets smaller as the cell gets larger.Thus, if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume.When this happens, the cell must divide into smaller cells with favorable surface area/volume ratios, or cease to function.That is why cells are so small.
What is ratio of surface area to volume?
surface area/ volume. wider range of surface area to volume is better for cells.
Do parietal cells have a cell membrane?
Yes, parietal cells (like all cells) have a cell membrane. Parietal cells have a huge surface area (their membrane has deep folds called canaliculi).
