$A-$ The symplastic system is the system of interconnected protoplasts.
$R-$ The apoplast is the system of adjacent cell walls that is continuous throughout the plant root,except at the Casparian strips of the endodermis in the roots.

What are the different means of transport in plants?

Read carefully the following statements and choose the right answer from the options given below.
$I$. Diffusion is a slow process and it does not depend upon the living system.
$II$. Usually,the process of diffusion does not need energy.
$III$. Diffusion can occur from one part of a cell to another part of the same cell,or from one cell to another,and from one tissue to another tissue.
$IV$. Diffusion is a rapid process over short distances,but extremely slow over long distances.

Define the following terms:
$(i)$ Passive transport
$(ii)$ Facilitated diffusion

Water is forced to move through the cell membranes from the endodermis onwards. What is this pathway called?

Which pathway is responsible for the majority of water transport in plants?
