How does the surface area change when a large cell gets smaller but has the same total volume?

The surface must get more spherical. When it reaches a perfect sphere the surface area cannot be reduced without also reducing the volume.

Which has the greater surface area one large cell or 27 smaller cells?
If the smaller cells' total volume is at least that of the larger cell then the smaller cells have the greater surface area.
Which cell has the greater surface area compared to its volume the large cell or one of the smaller cells?
A smaller cell has a higher surface area to volume ratio. A reason for this is volume is cubic (3D) and surface area is 2D so when surface area increases a little bit, the volume increases exponentially. And when the surface area shrinks a little bit, the volume decreases exponentially.
Why do larger animals keep their body heat better than smaller animals?
This is because of the surface to volume ratio. A small mammal has a larger surface area, as compared to its volume, than a large mammal does, so a small mammal's surface area to volume ratio is bigger. A large surface to volume ratio causes things to pass into the organism and out of the organism more easily, so a mammal with a large surface to volume ratio (a small mammal) will lose heat more easily in a cold environment than a mammal with a small surface to volume ratio (a large mammal).
How does a cell's ratio of surface area to volume change as the cell grews large?
It will decrease. In a larger cell, you have less surface area per volume.
Why is thermoregulation more effectively achieved in larger animals than in smaller ones?
Thremoregulation is easily achieved in large animal as they are able to retain the heat gained. In small animal the surface area is large as compares to their volume and hence gain or loose heat faster. large animal having smaller surface area as compared to their volume gain heat slower.
The effects of body size on heat loss?
A bigger animal has a small surface area in relation to their large volume. Smaller animals have a bis surface area to volume ratio which mean heat is easier to be lost.
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 the surface to volume ratio when the cell becomes larger?
When cells get smaller, the volume (as well as mass) decreases faster than the surface area so the surface:volume increases. Cells with a high surface:volume are more effective in receiving nutrients through diffusion. A cell (assume perfect sphere) with radius 2 has a surface area of 16pi and volume of 32pi/3. A cell with radius 3 has a surface area of 36pi and volume of 108pi/3. Also relatively speaking, volume can be thought of as y=x3 and surface area as y=x2. When there is a change in x, the change is more dramatic in the volume, so small cells have high ratios and large cells have low ratios.
Explain the importance of villi?
They increase the surface to volume ratio. This allows more stuff to come in contact with the wall in a limited volume. An example of this would be taking a large bag crumpling it up and sticking it in a smaller bag. You take up less volume, but the bag still has the same amount of surface.
What is the relationship between a cells surface area and 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 limit on the size to which a cell can grow.
How does the structure of the alveoli relate to the structure of the lungs?
Alveoli are similar to cells in the sense that they have a large surface area to volume ratio. This is advantageous since they depend on there surface to allow as much oxygen as possible to diffuse through. Therefore, the correct answer would be something like this : Since alveoli's have a large surface area to volume ratio, it oxygen to diffuse through. More oxygen can be absorbed. If the alveoli had a smaller surface area to volume ratio, it would be very difficult for oxygen to diffuse through. Therefore, it is advantageous for the alveoli to be small in volume, but great in surface area.
