AIIMS 2019 Biology Symplast and Apoplast MCQ Question

The symplast refers to the interconnected network of living cells in plants, where cytoplasmic connections through plasmodesmata facilitate the movement of water (H₂O), nutrients, and signaling molecules. Option C is incorrect because the symplast is indeed a living continuum, consisting of the cytoplasm of adjacent cells, allowing for cellular communication and transport. Option A is misleading as it suggests the symplast is non-living, while options B and D do not accurately describe the symplastic pathway, which excludes the cell wall and intercellular spaces that are part of the apoplast. Understanding the distinction between the symplast and apoplast is crucial for comprehending plant physiology and nutrient transport mechanisms.
