The saturation point of $\mathrm{CO}_2$ in $\mathrm{C}_4$ plants is

The saturation point of $\mathrm{CO}_2$ in $\mathrm{C}_4$ plants is
  1. $390 \mu \mathrm{l} / \mathrm{L}$
  2. $450 \mu \mathrm{l} / \mathrm{L}$
  3. $460 \mu \mathrm{l} / \mathrm{L}$
  4. $360 \mu \mathrm{l} / \mathrm{L}$

Solution

The optimum $\mathrm{CO}_2$ concentration for $\mathrm{C}_4$ plants is $360 \mu \mathrm{l} / \mathrm{L}$ or $360 \mathrm{ppm}$.
