Which of the following statements are correct regarding the factors affecting the absorption of water by plants?
$(i)$ In plants,the rate of water absorption is minimum at a soil temperature of $20^{\circ}C$ to $30^{\circ}C$.
(ii) The presence of capillary water is essential in the soil.
(iii) Poorly aerated soil shows a poor absorption rate.
(iv) $A$ low transpiration rate accelerates the rate of absorption of water in irrigated soil.
$(v)$ $A$ high concentration of solutes in soil water reduces the rate of absorption of water.

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.

Plants show temporary and permanent wilting. Differentiate between the two.

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?

$A.$ 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.
