$A$: Endodermis onwards,the movement of water occurs through the living part of the cell. $R$: The inner boundary of the cortex possesses an impermeable band of lignified matrix.

Which of the following phenomena is not associated with root pressure?

Which of the following statements are correct regarding the factors affecting absorption by plants?
$i$. In dicots,the guard cells are dumbbell shaped.
$ii$. The transport of food through phloem is bidirectional.
$iii$. Capillary water is available to plants.
$iv$. Lenticels are small,raised structures composed of compactly arranged complementary cells.
$v$. Stomatal transpiration occurs during day time only.
Choose the correct option:

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 substances across the cell membrane against the concentration gradient.
$III.$ In facilitated diffusion,special proteins help hydrophilic substances to be transported across the membrane.
$IV.$ In diffusion,molecules move against the concentration gradient in a random manner.
$V.$ Facilitated diffusion is faster than active transport.

How do short-distance transport and long-distance transport occur in plants?
$I -$ By diffusion
$II -$ By translocation (xylem and phloem)
$III -$ By active transport of cytoplasmic streaming
Select the correct combination for short-distance transport and long-distance transport respectively.

Select the correct option from the following.
