alleryLight saturation in photosynthesis typically occurs at
A100 per cent of full sunlight
B50 per cent of full sunlight
C1 per cent of full sunlight
D10 per cent of full sunlight
Answer & Solution
Correct answer: D. 10 per cent of full sunlight
**Your syllabus:** light saturation occurs at about 10% of full sunlight intensity.
Above this, other factors (CO2, temperature, water) become limiting.
**So in nature, light rarely limits photosynthesis except in shade.**
