Botany Photosynthesis in Higher Plants questions from NEET UG 2005.
As compared to a $\mathrm{C}_3$-plant, how many additional molecules of ATP are needed for net production of one molecule of hexose sugar by $\mathrm{C}_4$-plants?
Photosynthesis in $\mathrm{C}_4$ plants is relatively less limited by atmospheric $\mathrm{CO}_2$ levels because:
Photosynthetic active radiation (PAR) has the following range of wavelengths:
