Active transport:

[1 Mark]

• A. Helps in the transportation of water through the vacuole of root cells
• B. Helps in guttation through leaves of certain plants
• C. Helps in imbibition
• D. Helps in the transportation of minerals through the vacuoles in root cells

Answer 1

The correct option is D Helps in the transportation of minerals through the vacuoles in root cells

Active transport is the passage of a substance (mainly mineral salts and ions) from its lower concentration to its higher concentration through a living membrane by using the energy of the cell. The energy is supplied in the form of ATP. Active transport mechanisms maintain the right concentrations of ions and molecules in living cells. An incident of active transportation can be observed in the transportation of minerals through the vacuoles in the root cells.
