(i) Electron transport between PS-II to PS-I produces ATP by substrate level phosphorylation.
(ii) In PS-II, the oxidation of two water molecules produces four electrons, four protons, & a single O₂.
(iii) PS-II reduces NADP+ to NADPH.
(iv) Light and dark reactions are stopped in the absence of light.
(v) Calvin cycle occurs in the grana of chloroplast.
(vi) ATP is produced during light reaction via chemiosmosis.
(vii) The C₄ plants respond to higher temperatures while C₃ plants have a much lower temperature optimum.
(viii) Temperate plants have a higher temperature optimum than the plants adapted to tropical climates.
(ix) Some C₃ plants are allowed to grow in CO₂ enriched atmosphere that leads to higher yields.
(x) Water stress causes the stomata to remain open hence enhancing the CO₂ availability.
