Which of the Following Could Contribute to Slower Plant Growth

Multiple Choice

Which of the following could contribute to slower plant growth in saline soils?

A) the need to pull harder to obtain water from soil containing high concentrations of salts, potentially limiting both photosynthesis and cell expansion
B) higher rates of respiration in roots that have to use energy to exclude salts from entering the xylem
C) higher salt concentrations in leaves, potentially shortening their life-span
D) these choices are correct.
