QUESTION 1 Plants take up calcium in the form of Ca2+ and sulfur in the form of SO42 Which statement about these ions is correct? Ca2+ binds to soil particles while SO42 is found dissolved in soil water Ca2+ is found dissolved in soil water while SO4 binds to soil particles both are found primarily in soil water both bind to soil particles QUESTION 2 How do plant processes help to remove the ions bound to soil particles from the soil, so they can be taken up from the soil water? root cells actively pump metals into the soil, and the metals take the place of nutrient ions root cells actively pump hydrogen ions into the soil, and the hydrogen ions take the place of nutrient ions root cells release carbon dioxide, which reacts with water to create hydrogen ions that take the place of nutrient ions QUESTION 3 Which steps of nutrient uptake by roots require energy expenditure by the plant? release of nutrient ions from soil particles into soil water uptake of nutrient ions from soil water into root hair cells both neither Click Save and Submit to save and submit.

Explanation / Answer

Answer -

Question 1- The option (a) is correct. Calcium ions bind to soil while sulphate ion is found dissolved in soil water.

Question 2 - (c) The root cells release carbon dioxide which react with water to create hydrogen ion that takes place of nutiemt ions .

Explanation - Due to roots are continuous respiration ,so produce carbon dioxide gas.

Question 3- (b) Uptake of nutrients from soil into root hair cells.

Explanation - Because this is active process .
