NCERT Class 11 Biology Chapter 11 Photosynthesis in Higher Plants Test Mock Test
This free online test covers Chapter 11, Photosynthesis in Higher Plants, from the NCERT Class 11 Biology textbook. The 30 questions are written directly from the chapter — definitions, processes, worked examples and the points the book italicises — so a score here tells you how much of the chapter actually stuck, not how well you guess. Each answer carries an explanation that says why the right option is right and why the other three fail, which is where most of the learning happens. Attempt it after your first read of the chapter, then again before the exam. There is no negative marking, and you can review the full solution the moment you submit.

Q1.An experiment in which one half of a leaf is enclosed in a test tube with KOH soaked cotton while the other half is left exposed to air, and both halves are later tested for starch, is designed to show that photosynthesis requires:
- ACarbon dioxide
- BChlorophyll
- CLight
- DWater
Q2.From his bell jar experiments with a burning candle, a mouse and a mint plant, Joseph Priestley hypothesised that:
- AThe oxygen evolved by green plants comes from water and not from carbon dioxide
- BThe green substance of plants is located in special bodies within plant cells
- CSunlight is essential for the process by which plants purify the air
- DPlants restore to the air whatever breathing animals and burning candles remove
Q3.T. W. Engelmann illuminated the green alga Cladophora with a spectrum split by a prism, in a suspension of aerobic bacteria. What did the bacteria reveal?
- AThey accumulated in the green region, showing that green light drives photosynthesis best
- BThey were killed in the blue and red regions, showing that these wavelengths damage the alga
- CThey distributed themselves evenly, showing that all wavelengths are equally effective
- DThey accumulated in the blue and red regions, giving the first action spectrum of photosynthesis
