In plants, the tonoplast facilitates the transport of a number of ions and other materials

Question

In plants, the tonoplast facilitates the transport of a number of ions and other materials (A) Against concentration gradient into vacuole (B) Along concentration gradient into vacuole (C) Along concentration gradient into gas vacuoles (D) Against concentration gradient in contractile vacuole

Tardigrade Admin · Accepted Answer

Plant cells do not contain gas and contractile vacuole and movement of molecules across tonoplast is always against concentration gradient and require energy.

Q. In plants, the tonoplast facilitates the transport of a number of ions and other materials

Against concentration gradient into vacuole

Along concentration gradient into vacuole

Along concentration gradient into gas vacuoles

Against concentration gradient in contractile vacuole

Plant cells do not contain gas and contractile vacuole and movement of molecules across tonoplast is always against concentration gradient and require energy.
