Which of the following is not observed duringapoplastic pathway ?a)The...
Introduction:
The apoplastic pathway is one of the two major pathways by which water and solutes are transported through plants from the roots to the shoots. It involves the movement of water and solutes through the cell walls and intercellular spaces of plant tissues, bypassing the cell membranes.
Explanation:
The correct answer is option B - "The movement is aided by cytoplasmic streaming." This is because cytoplasmic streaming is a characteristic of the symplastic pathway, not the apoplastic pathway.
Distinguishing features of the apoplastic pathway:
The apoplastic pathway has several distinguishing features that differentiate it from the symplastic pathway:
1. Movement does not involve crossing of cell membrane:
- In the apoplastic pathway, water and solutes move through the cell walls and intercellular spaces without crossing the cell membranes.
- This is in contrast to the symplastic pathway, where water and solutes move through the cytoplasm and plasmodesmata, which are channels connecting the cytoplasm of adjacent cells.
2. Apoplastic pathway is continuous and does not provide any barrier to water movement:
- The cell walls and intercellular spaces form a continuous network throughout the plant, allowing for the free movement of water and solutes.
- There are no barriers or selective membranes that impede the flow of water through the apoplastic pathway.
3. Movement of water occurs through intercellular spaces and cell walls:
- Water enters the apoplast at the root surface and moves through the intercellular spaces and cell walls, facilitated by the cohesive and adhesive properties of water.
- It can move laterally between cells and travel upwards through the xylem vessels.
4. No involvement of cytoplasmic streaming:
- Cytoplasmic streaming refers to the movement of cytoplasm within plant cells.
- It occurs in the symplastic pathway, where water and solutes move through the cytoplasm and plasmodesmata.
Conclusion:
In summary, the movement through the apoplastic pathway does not involve crossing of cell membranes, is aided by the continuous apoplastic network, occurs through intercellular spaces and cell walls, and does not involve cytoplasmic streaming.

Which of the following is not observed duringapoplastic pathway ?a)The...
Cytoplasmic streaming refers to the movement of cytoplasm within plant cells. It involves the flow of organelles and other substances along cytoskeletal elements like microfilaments and microtubules. However, cytoplasmic streaming is not directly involved in the apoplastic pathway of water movement in plants.
The apoplastic pathway is one of the two pathways through which water can move through plant tissues. In the apoplastic pathway, water moves through the interconnected cell walls and intercellular spaces without crossing the cell membrane. The movement of water occurs through the physical structure of the cell walls and the interconnectedness of the apoplast (the extracellular space outside the plasma membrane).
Option A (The movement does not involve crossing of cell membrane), Option C (Apoplastic is continuous and does not provide any barrier to water movement), and Option D (Movement of water occurs through intercellular spaces and the wall of the cells) are all characteristics associated with the apoplastic pathway of water movement in plants.
Therefore, the correct answer is B: The movement is aided by cytoplasmic streaming, as cytoplasmic streaming is not directly involved in the apoplastic pathway.
