Which of the following statements is incorrect?
Options
- ADifferent substances move independently along their concentration gradient in mass flow.
- BActive absorption of ions from the soil by the root is mainly affected by respiratory activity of root.
- CThe translocation of organic solutes in sieve tube members is supported by mass flow.
- DRoot pressure develops due to active absorption.
Correct answer
A. Different substances move independently along their concentration gradient in mass flow.
Step-by-step solution
Mass or bulk flow is the movement of substances in bulk from source to sink as a result of pressure differences. Mass flow is not to be confused with diffusion which depends on concentration gradients within a medium rather than pressure gradients of the medium itself.
