Question

Assertion (A): Apoplast is a non-living system, while (B) symplast is a living system.
Reason (R): Apoplast uses intercellular spaces for movement, while symplast crosses the cell wall and cell membranes.

• A. Both A & B are true and R explains A
• B. Both A & B are true and R doesn't explain A
• C. A is true and B is false
• D. Both A & R are false

Answer 1

The correct option is A

Both A & B are true and R explains A

Apoplast is non-living and involves cell walls and intercellular spaces. It is continuous throughout the plant except at casparian strips of endodermis. Symplast is living and involves cytoplasm and plasmodesmata through which neighbouring cells are connected.
