The transport of gases,hormones,photosynthates,and organic solutes in plants is:

In a girdled plant,when water is supplied to the leaves above the girdle,leaves may remain green for some time,then wilt and ultimately die. What does it indicate?

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.
Choose the correct option.

In the given flow chart, the pathway of water movement is shown from soil to xylem. Identify $A-E$ and choose the correct option accordingly.

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.
