Which of the following is an example of diffusion in plants?

Diffusion is faster in:

Why the rate of diffusion of a substance along the concentration gradient does not increase continuously, while the concentration difference of the molecules across the membrane increases?

    Transport proteins of endodermal cells are …A… where a plant adjusts the …B… and …C… of

solutes that reaches the …D…

Choose the correct combination of A-D from the given options

Movement of molecules takes place along the concentration gradient 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

    Which of the following affects the rate of diffusion?

Which of the following is NOT an example of diffusion?

    Graham’s law is correlated with

Read carefully the following statements and choose the right answer from the options given below

I.    Diffusion is a slow process and it do not depends upon the living system

II.    Usually process of diffusion does not need energy

III.    Diffusion can occur from one part of a cell to another part of the same cell or from one cell to another and from one tissue to another tissue

IV.    Diffusion is a rapid process over short distance, but extremely slow over long distances

    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
