What are some factors that could limit the ability of cells to survive quizlet?
Terms in this set (6)
- volume – surface area ratio. cell dependent on surface area for diffusion. …
- nucleus. must have enough DNA to support size. …
- contact inhibition. if too many (over crowded) = stop mitosis.
- limited life span. when cell gets too old, mitosis stops.

What are the two main factors that limit cell size?
The factors limiting the size of cells include: Surface area to volume ratio (surface area / volume) Nucleo-cytoplasmic ratio. Fragility of cell membrane.
What factor limits cell growth?
Cell growth is limited by rates of protein synthesis, by the folding rates of its slowest proteins, and—for large cells—by the rates of its protein diffusion.
What are 3 factors that limit cell size?
Factors limiting the size of cells include:
- Surface area to volume ratio. (surface area / volume)
- Nucleo-cytoplasmic ratio.
- Fragility of cell membrane.
- Mechanical structures necessary to hold the cell together (and the contents of the cell in place)
What limits how big a cell can be?
Cell size is limited by a cell's surface area to volume ratio. A smaller cell is more effective and transporting materials, including waste products, than a larger cell. Cells come in many different shapes. A cell's function is determined, in part, by its shape.
Is there a limit for cell?
1 Answer. The size of a cell is limited by cell's surface area-to-volume ratio. A cell differs not only in its shape but also in its size. While a few cells are large enough to be seen by naked eyes, most cells are microscopic in size.
What limits the size of a cell and why?
Cell size is limited by a cell's surface area to volume ratio. A smaller cell is more effective and transporting materials, including waste products, than a larger cell. Cells come in many different shapes. A cell's function is determined, in part, by its shape.
Why are there limits to cell size?
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.
What are limiting factors in cell division?
Cells only divide when they receive specific signals from proteins called mitogens, thus the presence of mitogens can limit cell division. Mitogens are needed for cell division in healthy cells and are released depending on what cells the body needs.
What factor limits the size of free living cells?
The single factor that limits the size of most of the cell is the surface volume ratio. The size of the cell gets limited by the nucleo-cytoplasmic ratio, which determines the range of control of metabolic ratio and the ratio of surface to volume.
What are the limits to cell division?
The concept states that a normal human cell can only replicate and divide forty to sixty times before it cannot divide anymore, and will break down by programmed cell death or apoptosis.
What are the 3 factors that limit cell size?
Factors limiting the size of cells include:
- Surface area to volume ratio. (surface area / volume)
- Nucleo-cytoplasmic ratio.
- Fragility of cell membrane.
- Mechanical structures necessary to hold the cell together (and the contents of the cell in place)
What limits cell growth and division?
External Limits Cells only divide when they receive specific signals from proteins called mitogens, thus the presence of mitogens can limit cell division. Mitogens are needed for cell division in healthy cells and are released depending on what cells the body needs.
What things limit the size of a cell?
Cell size is limited by a cell's surface area to volume ratio. A smaller cell is more effective and transporting materials, including waste products, than a larger cell. Cells come in many different shapes. A cell's function is determined, in part, by its shape.
What three things limit the size that a cell could be?

What can limit the size of the cell?
Cell size is limited by a cell's surface area to volume ratio. A smaller cell is more effective and transporting materials, including waste products, than a larger cell. Cells come in many different shapes.

What factors limit the size of a cell quizlet?
The key factor that limits the size of a cell is the ratio of its surface area to its volume.
Why does a cell limit its size?
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.
What limits how large a cell can be?
