What is the relationship between surface area to volume ratio and the rate of diffusion?
The higher the ratio, the faster the rate of diffusion
How does surface area work?
It would help if the question was less obscure. What do you mean by "work"? How the surface area affects chemical processes (for example the surface area of catalysts), or diffusion, or surface areas and friction?
In what way is the surface area more important for cells than volume?
For example, the amount of nutrients a cell can absorb are proportional to its surface area.
Why surface area important?
All chemical reactions take place on surfaces = so very important
Why is it important that the surface of the solar panel has a large area?
so it can get more sun
How are living organisms adapted to increase posibility of diffusion?
they have a large surface area and are important
How does surface area affect diffusion rate?
Diffusion is the movement of particles across a selectively permeable membrane, from a high concentration to a low concentration. So the larger the surface area, the quicker the rate of diffusion because there is more space to diffuse in.
Why is a large surface area necessary for the alveoli in the lungs?
According to fick's law rate of diffusion =(proportional to)= Surface area x Diffusion gradient Diffusion Pathway thickness So for a sufficient rate of diffusion, Surface area must be large The diffusion pathway is already at it's minimun of 1 cell thick and the gradient is harder to adjust. There are around 600 million alveoli in the lungs that have a cummulitive surface area of around 70m2.
How does surface area to volume ratio of a cell affect rate of diffusion?
The surface area to volume ratio of a cell affects the rate of diffusion in that the higher the ratio, the faster the rate of diffusion. This is a directly proportional relationship.
What influences the rate of diffusion?
The rate of diffusion increases with temperature. The rate of diffusion also increases with the concentration gradient and the surface area.
Why small particle has more surface area than larger particle?
That depends upon the shape of the particles. * If they are spherical, the surface area is 4*pi*r^2, where r is the radius of the particle. * If they are cuboidal, the surface area is b*w*h, where b, w, h are the lengths of the sides
What 3 things limit cell size?
DNA, Diffusion, and Surface Area to Volume Ratio.
What is the relationship between surface area to volume ratio and the rate of diffusion?

What is diffusion in the villi?
Same as anywhere else on the cell. The function of the villi is to increase the surface area, and thus the rate of diffusion.
What things limit cell size?
DNA, Diffusion, and Surface Area to Volume Ratio.
How can capillaries allow gas exchange?
Large surface area + small radius for diffusion.
