$(1)$ The apoplastic movement of water occurs exclusively through the intercellular spaces and the walls of the cells.
$(2)$ The symplastic system is the system of interconnected protoplasts.
$(3)$ Casparian strips are present in the apoplast pathway.
$(4)$ Transport of water is slow in the symplast compared to the apoplast.

$A.$ Most researchers agree that water is mainly 'pulled' upward through the plant, where transpiration is the driving force.
$B.$ Less than one percent of water reaching the leaves is used in plant growth and photosynthesis.
$C.$ Cobalt chloride paper turns blue on absorbing water.

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.

- Transport of water and minerals in $Xylem$ is $\underline{A}$.
- Transport of organic and mineral nutrients is $\underline{B}$.

Choose true and false statements from the following:
$I.$ Mycorrhizal association between fungus and root of plant $(Pinus)$ is often obligate.
$II.$ $Pinus$ and orchid seeds can germinate and grow into plant in absence of mycorrhizal association.
$III.$ Absorption of water along with mineral solute by root hairs is purely a process of diffusion.
$IV.$ In apoplast pathway,movement of water takes place through cell wall and intercellular spaces.
$V.$ Fungal hyphae provide sugar and organic internal to root.
