Practice CBSE Class 11 Photosynthesis in Higher Plants in the app →Photosynthesis primarily occurs in which organelle?Chlorophyll absorbs light most strongly inThe Calvin cycle (dark reactions) occurs inThe oxygen released during photosynthesis comes fromThe enzyme that fixes CO₂ in the Calvin cycle isThe first stable product of CO₂ fixation in C4 plants isIn photosynthesis, the oxygen released into the atmosphere comes fromInside a leaf cell, photosynthesis is carried out inWhy do healthy leaves look green?The molecular oxygen released during photosynthesis comes fromCyclic photophosphorylation differs from non-cyclic in that itPer Mitchell's chemiosmotic hypothesis, ATP synthesis in chloroplasts is driven byThe enzyme RuBisCO catalyses the joining of CO₂ to which molecule?To synthesise one molecule of glucose, the Calvin cycle must consumeC3 plants are so named becauseKranz anatomy of C4 plants isPhotorespiration in C3 plants is wasteful becauseBlackman's law of limiting factors says thatThe MAIN photosynthetic pigment in green plants is:Light reactions of photosynthesis occur in the:In photosynthesis, the source of O2 released into the atmosphere is:In the Z-scheme of photosynthesis, electrons flow:In the Calvin cycle, CO2 is fixed by the enzyme:The C4 pathway (Hatch-Slack) uses which enzyme for the initial CO2 fixation?CAM plants (like cactus and pineapple) open their stomata mainly:The colour of light LEAST absorbed by chlorophyll (and most reflected by leaves) is:Blackman's law of LIMITING FACTORS states that the overall rate of photosynthesis is determined by:
