Photosynthesis & Plant MCQs with Answers

One-liner

The Hatch-Slack Pathway is associated with C4 plants, where it serves as a carbon-concentrating mechanism that minimizes photorespiration.

One-liner

PS II receives electrons from the splitting of water during the light reactions of photosynthesis.

One-liner

The process that converts carbon dioxide into glucose is called Photosynthesis.

One-liner

Chlorophyll is required for the process of Photosynthesis, which is how green plants convert sunlight into chemical energy.

One-liner

The first stable product of the dark reaction (Calvin cycle) is a 3-carbon molecule called 3-phosphoglycerate (3-PGA).

One-liner

The green colour of plants is due to the presence of Chlorophyll, a pigment essential for photosynthesis.

One-liner

During the light-dependent phase, water (H₂O) is split into 2H⁺, 2e⁻ and ½O₂ through the process of photolysis.

One-liner

The process of ATP generation on thylakoid membranes is called Chemiosmosis.

One-liner

The reaction in which solar energy is transferred to glucose from ATP and NADPH₂ and takes place in the stroma is called the Dark reaction (Calvin cycle).

One-liner

Red light is the most important wavelength for photosynthesis as chlorophyll absorbs it most efficiently.
