Question

what is symplast pathway.? write 4 correct points.

Answer 1

(1).The symplast of a plant is the inner side of the plasma membrane in which water and low-molecular-weight solutes can freely diffuse.

(2).The plasmodesmata allow the direct flow of small molecules such as sugars, amino acids, and ions between cells. Larger molecules, including transcription factors and plant viruses, can also be transported through with the help of actin structures

(3).This allows direct cytoplasm-to-cytoplasm flow of water and other nutrients along concentration gradients.

(4).Once solutes reach the endodermal cells thorough apoplastic flow, they are forced into the symplastic pathway due to the presence of the Casparian strip
