Question

In plants,the tonoplast facilitates the transport of a number of ions and other materials (1)Against concentration gradient into vacuole (2)Along concentration gradient into vacuole (3)Along concentration gradient into gas vacuoles (4)Against concentration gradient in contractile vacuole

Answer 1

Answer:

1)against concentration gradient into vacuoles

Explanation:

Tonoplast is the membrane in vacuole which maintain the high concentration of ions.

and helps in transport of various ions like calcium ions and nitrate ions, potassium ions against concentration gradient with the help of ATP. This transport maintains osmotic pressure inside the vacuole.

Answer 2

Answer:

In plants, the tonoplast facilitates the transport of a number of ions and other materials against concentration gradient into vacuole.

Explanation:

• The tonoplast is a membrane of vacuole in plants which maintains the concentration of ions and other materials and also balance the osmotic pressure.

• Vacuoles of trees are much bigger than animals because they need more water, inorganic and organic matter.

• Tonoplast separates vacuole and cytoplasm and facilitates uphill transport of ions and other materials, which facilitates through cytoplasm to vacuole by tonoplast membrane against the concentration gradient because vacuoles have high concentration of ions and other important substances.

• The transport happens against the concentration gradient, so it requires energy in form of ATP.

So, from the above discussion, it is proved that, in plants, the tonoplast facilitates the transport of a number of ions and other materials against the concentration gradient into vacuole.
