Explain: Apoplast pathway.

Consider the following statements and choose the correct answer from the options given below:
$I$. $A$ dry live seed still contains water.
$II$. $A$ mature maize plant absorbs about $3 \ L$ water per day.
$III$. $A$ mustard plant takes up water equal to its weight in about five hours.
$IV$. Water is not considered as the limiting factor for plant growth and productivity.

Select the correct statement$(s)$ regarding bulk flow.
$I-$ In tall plants,water,minerals,and food are moved by a bulk flow system.
$II-$ This type of movement is achieved through a pressure difference between two points.
$III-$ In bulk flow,substances,whether in solution or suspension,move at the same pace as in a flowing river.
$IV-$ This process is similar to diffusion.

The cell wall is permeable and not a semipermeable structure; this can be best deduced from the passage of water and mineral salts from:

Which of the following statements is/are not incorrect?
$(i)$ Water and minerals,and food are generally moved by a mass or bulk flow system.
$(ii)$ Bulk flow can be achieved either through a positive hydrostatic pressure gradient or a negative hydrostatic pressure gradient.
$(iii)$ The bulk movement of substances through the conducting tissues of plants is called translocation.
$(iv)$ Xylem translocates organic and inorganic solutes,mainly from roots to the aerial parts of the plants.
$(v)$ Phloem translocates water,mineral salts,some organic nitrogen and hormones,from the leaves to other parts of the plants.

Which one of the following does not help in molecule transport?
