Factors affecting gas diffusion?
stomatal movements( it depends on light, temperature, condition of the plant, glucose & sucrose concentrations, ion concentrations....) , intra cellular gaps in spongy paranchyma, atmospheric & plant pressure, amount of gases in the atmosphere, ...... are the factors which effect the gas exchange.
Effect of the presence of other molecules on the diffusion of a given substance?
It explodes
What are 3 factors that can have a effect on the rate of diffusion?
Diffusion rate varies with concentration difference, temperature and dimension of transfer path (area or distance).
How does temperature effect diffusion rates?
Temperature and diffusion rates are usually linearly proportional. As temperature increases diffusion rate also increases and vice versa. In most cases, diffusion rate will reach 0 after saturation or the maximum possible temperature.
What is the odor of sucrose?
Sucrose has no odor.
Why is a dialysis membrane not permeable to sucrose?
No; the sucrose molecule (as a disaccharide) is too large to pass through by passive diffusion. Glucose, on the other hand, (a monosaccharide) is able to permeate the dialysis tubing. In the body, glucose/sucrose is transmitted across membranes though the use of active/facilitated diffusion.
What are the effect of ozone diffusion and green house effect?
Ozone diffusion and greenhouse effect increase the temperature on earth. This can cause various natural calamities.
Why did osmosis, but not diffusion of sucrose molecules, occur across the dialysis membrane containing 20% sucrose solution?
Sucrose cannot diffuse across a dialysis tubing. This is because it's size is too large to go through the tubing. Water can diffuse across.
How do temperature effect the rate of diffusion?
higher temp = higher rate of diffusion
What effect does NaCl have on glucose diffusion?
No it does not
When could diffusion be dangerous?
pollution that can make us medically unwell is an effect of diffusion
Does diffusion effect cell size?
Yes
Factors affecting gas diffusion?
stomatal movements( it depends on light, temperature, condition of the plant, glucose & sucrose concentrations, ion concentrations....) , intra cellular gaps in spongy paranchyma, atmospheric & plant pressure, amount of gases in the atmosphere, ...... are the factors which effect the gas exchange.
How did cultural diffusion effect ancient Greece?
it had no effect
What is the effect of the density of liquid on the rate of diffusion?
The increase in density will decrease the rate of diffusion. There is an inverse relation between density and rate of diffusion.
The movement of particles from a high concentration to a low concentration?
diffusion
Does distance effect rate o diffusion?
Yes if the distance that the molecule has to travel is long then the rate of diffusion will be slower.
