Some photosynthetic organisms contain chloroplasts that lack photosystem II yet can survive. The best way to detect the "lack of photosystem II" in these organisms would be ______?

Some photosynthetic organisms contain chloroplasts that lack photosystem II yet can survive. The best way to detect the "lack of photosystem II" in these organisms would be ______?

کچھ فوٹوسنتھیٹک جانداروں میں کلوروپلاسٹ ہوتے ہیں جن میں فوٹو سسٹم II کی کمی ہوتی ہے لیکن وہ زندہ رہ سکتے ہیں۔ ان جانداروں میں "فوٹو سسٹم II کی کمی" کا پتہ لگانے کا بہترین طریقہ ______ ہوگا؟
Explanation

The best way to detect the "lack of photosystem II" in these organisms is to test for liberation of O₂ in the light.

Photosystem II is crucial for oxygen evolution during photosynthesis, so its absence will result in no oxygen being released.
