Question

The compensation point of CO₂ for C₃ plants is__________.

Answer 1

Compensation point:-

• The compensation point for carbon dioxide is the point where the plant does not absorb any ${\mathrm{CO}}_2$ from the surrounding
• As the levels of ${\mathrm{CO}}_2$ used in photosynthesis is equal to the amount of ${\mathrm{CO}}_2$released by respiration and photorespiration.
• Carbon dioxide compensates at a range of $25-100\mathrm{ppm}$.
• Hence, in ${\mathrm{C}}_3$ plants, the value of the compensation point for ${\mathrm{CO}}_2$ is $25-100\mathrm{ppm}$ .

Therefore, the compensation point of ${\mathrm{CO}}_2$ for ${\mathrm{C}}_3$ plants is $25-100\mathrm{ppm}$
