(N/A) The movement of water through the root occurs via two distinct pathways:
$1$. Apoplast Pathway: The apoplast is the system of adjacent cell walls that is continuous throughout the plant,except at the Casparian strips of the endodermis in the roots. Water movement occurs exclusively through intercellular spaces and cell walls. It does not involve crossing the cell membrane and is dependent on a gradient. It is a passive process involving mass flow.
$2$. Symplast Pathway: The symplastic system is the system of interconnected protoplasts. Neighbouring cells are connected through cytoplasmic strands that extend through plasmodesmata. Water enters the cells through the cell membrane,making the movement relatively slower. It is also a passive process occurring down a potential gradient,though it may be aided by cytoplasmic streaming.
Regarding active transport: Neither the apoplast nor the symplast pathway of water movement requires active transport. Water movement in both pathways is passive,driven by water potential gradients.
