Question

Select the correct statement with respect to minerals present in soil.

• A. Minerals can move freely across the membrane.
• B. Minerals do not require the aid of transporters.
• C. Minerals in the soil are usually found dissolved in water.
• D. Minerals are present in their elemental forms in the soil.

Answer 1

The correct option is C Minerals in the soil are usually found dissolved in water.

Plants require many minerals in many different amounts. Carbon, hydrogen, oxygen, phosphorus, potassium, nitrogen are required in large quantities. Sulphur, magnesium, calcium are required in moderate quantities. Minerals in the soil are usually found dissolved in water. These are present in their ionic forms. Since they are charged particles, they cannot move across the membrane freely. To move across the membrane, they require the assistance of specialized transporter proteins present in the membrane.
