During the uptake of ions in the second phase, absorption of minerals occurs
1 By passive movement of ions
2 With expenditure of energy
3 Without expenditure of energy
4 None of the above
Explanation:
In the second (final) phase of uptake, the ions are taken in slowly into the 'inner space' - the symplast of the cells. The entry or exit of ions to and from the symplast requires the expenditure of metabolic energy, which is an active process.

During the uptake of ions in the first phase, absorption of minerals occurs through
1 Active movement of ions
2 Passive movement of ions
3 Both 1 and 2
4 None of the above
Explanation:
In the first phase, an initial rapid uptake of ions into the 'free space' or 'outer space' of cells - the apoplast, is passive.

2 Apoplast-plasmodesmata
3 Potassium - Readily mobilisation
4 Bakane of rice seedlings -F Skoog
