# What increase faster in a cell surface area or volume?

volume increases faster than the surface area.

### What happens to the volume of an object as its surface area increases?

In general, the volume will also increase. If the shape remains the same, the volume will increase faster than the surface area. Specifically, the surface area is proportional to the square of an object's diameter (or any other linear measurement), while the volume is proportional to the cube of any linear measurement.

### How does surface area to volume ratio affect heat loss?

The surface-to-volume ratio is a mathematical relationship between the volume of an object and the amount of surface area it has. This ratio often plays an important role in biological structures. An increase in the radius will increase the surface area by a power of two, but increase the volume by a power of three.

### Why do the alveoli have a large surface area?

"Gas exchange is by diffusion from the gas contents in the lungs to the blood vessels in the pulmonary aveolus. The many indentations within the lung act to increase the surface area in the volume occupied by the lungs." To improve on the previous answer, the larger the surface area compared to the volume (or size) of the cell, the faster the rate of diffusion through the cell membrane. So with a larger surface area…

### What is the relationship between a cell's surface area and its volume?

The relationship is usually expressed as a ratio: surface area divided by volume. Small cells have a large surface area to volume ratio, whilst large cells have a much smaller value. This is important because the cell absorbs the things it needs, and gets rid of what it doesn't need, through the surface. If the cell gets too large, not enough exchange can take place to keep the cell going, so there is a natural…

### What happens to the surface area and volume of a cell as it becomes larger?

They both increase with increasing cell radius (if we model a cell as a sphere). However, the rate of increase of the surface area is in general slower (dA/dr = 8Ï€r) compared to the rate of increase of the volume (dV/dr = 4Ï€r2). This would mean that with increasing cell size, the surface area to volume ratio is becoming smaller and smaller, giving a cell less surface area for the transport of nutrients for a…

### What can large cells do that will increase their total surface area to volume ratio?

They can't really. That's the problem and that is why cells are so small. As they increase in size, their surface area to volume ratio gets smaller, so they do not have enough surface area to support their volume. Now, if we picture something like a small intestine that has lots of projections or something like the mitochondria where there are lots and lots of folds to increase surface area then I suppose cells could…

### Why are cells microscopic due to volume ratios?

The smaller a cell is, the greater the ration of Surface Area to Volume. As the cell size increases, the ratio of surface area to volume decreases. Volume will increase rapidly while surface area increases slowly. Cells must maintain a balance between surface area and volume because the amount of surface area determines how much food it can take in and how much waste it can remove. The greater the surface area, the longer it…

### Does the brain hypothalamus have a great-surface-area to volume?

This question can't be answered the way it is stated. You can compare the ratio of surface area to volume for two things of different sizes - say an elephant and a mouse. In general, smaller things have a greater surface to volume ratio. That's why you would grind something up to increase it's surface area and make it dissolve faster. If you're just talking about the numbers, you would have to say what units…
