Question

Which of the following statements is TRUE? 

विकल्प

• The second phase of absorption of ions in plants occurs from the apoplast.

• The entry or exit of ions to and fro from the symplast requires passive movement of ions

• Metabolic energy is required for the movement of ions through the apoplast.

• The ions are taken into the free space of the apoplast through the ion channel.

Answer 1

The ions are taken into the free space of the apoplast through the ion channel.

Explanation:

From the symplast, plants absorb ions in the second phase. Ions must actively move in order for them to enter or leave the symplast. Ion transport across the symplast requires metabolic energy.
