In terms of maximizing diffusion, what was the most effective size cube that you tested?
For maximizing diffusion, the 1cm cube was the most effective.
Why was that size the most effective at maximizing diffusion? What are the important factors that affect how materials diffuse into cells or tissue?
the 1cm cube was the most effective because it has a smaller surface area, and this makes it easier to cover the whole thing. Important factors that affect diffusion in cells or tissues are temperatures, materials, size and polarity.
If a large surface area is helpful to cells, why do cells not grow to be very larger?
surface area effects volume and if an object has a high volume it will take a greater amount of time to diffuse even though it may have a lot of surface area. This is why cells do not grow very larger.
You have three cubes, A,B and C. They have surface to volume ratios of 3:1, 5:2 and 4:1 respectively. Which of these cubes is going to be the most effective at maximizing diffusion, how do you know this?
the most effective ratio cube is 4:1 because of the balance of surface area to volume, it will have the most effective diffusion out of the three cubes.
How does your body adapt to surface area-to-volume ratios to help exchange gasses?
Our bodies have adapted in order to use large surface area organs that help exchange gases better. This is due to the surface area-volume ratio. An example of this is that our lungs use gasses like oxygen and carbon dioxide.
why can’t certain cells, like bacteria, get to be the size of a small fish?
some cells can’t grow larger because when the surface area grows the volume will also grow. The more volume that is there means that the cell will diffuse very slowly.
What are the advantages of large organisms being multi-cellular?
The advantages of large organism being multi cellular are that they are ore complex compared to a normal cell.
