Which of the following is not observed during the apoplastic pathway?
Options
- AThe movement does not involve crossing of cell membrane
- BThe movement is aided by cytoplasmic streaming
- CApoplast is continuous and does not provide any barrier to water movement
- DMovement of water occurs through intercellular spaces and walls of the cells
Correct answer
B. The movement is aided by cytoplasmic streaming
Step-by-step solution
Inside a plant, the apoplast is the space outside the plasma membrane within which material can diffuse freely. It is interrupted by the Casparian strip in roots, by air spaces between plant cells and by the plant cuticle.The apoplast pathway comprises of non living components of a plant body i.e., intercellular spaces and cell wall. Apoplastic pathway the movement does not involve crossing of cell membrane, symplastic movement is aided by cytoplasmic streaming. Apoplast is continuous and does not provide any barri
