Which of the following processes is primarily driven by diffusion?

What happens to the rate of diffusion as temperature increases?

When a molecule moves across a membrane independent of other molecules, the process is called

Diffusion is the net movement of particles from:

    Choose the correct option given below

The diffusion of water across a selectively permeable membrane is called:

    Choose, true and false statements from the following and select the correct option from the set (a-d) given below

I.    Diffusion is an important process of transport in plants since it is the only means for gaseous movement within the plant body

II.    In active transport, pumps are proteins that use energy to carry substance across the cell membrane against concentration gradient

III.    In facilitated diffusion, special proteins helps hydrophilic substances to be transported across the membrane

IV.    In diffusion, molecules move against concentration gradient in a random manner

V.    Facilitated diffusion is faster than active transport

Following statements are related with the diffusion of coloured molecules across a membrane. Select the correct statement, which shows the fastest rate of diffusion?

Diffusion, a process occur(s) along the concentration gradient is actively involved in

    Which of the following statements are true/false?

I.    The positive hydrostatic pressure is called turgor pressure.

II.    Wall pressure exerts to prevent the increase of protoplasm size.

III.    Diffusion is more rapid in liquids than in gases.

IV.    Diffusion of water through a semi-permeable membrane is called imbibition.

V.    Osmosis is movement of substance, which takes place along a diffusion gradient
