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

a)

I, II, III and IV

b)

I, II, III are true, while IV and V are false

c)

IV and V are true, while I, II and III are false

d)

Only II, III, IV are true while I and V are false

Answer Key : (b) -

(b)

Diffusion is an important process of transport. It is also related to gaseous exchange in plants. Facilitated diffusion is comparatively a slow process than active transport and transport of molecule occurs along the concentration gradient in diffusion
