The symplast of a plant is the inner side of the plasma membrane in which water and low-molecular-weight solutes can freely diffuse. Symplast cells have more than one nucleus.

What is symplast in plants?

noun, plural: symplasts. (botany) A system of interconnected protoplasts contained by plasmalemma, and linked by plasmodesmata. Supplement. In vascular plants, there are two pathways through which water and ions passes from the root hair to xylem tissues. These routes involve apoplast and symplast.

What forms symplastic system?

Symplastic transport is mediated by plant specific structures called plasmodesmata, which are plasma membrane-lined pores that traverse the cell walls of adjacent cells thus connecting their cytoplasms. ... Traffic via plasmodesmata is highly regulated, and callose turnover is known to be one mechanism.
