Mark the given statements True (T) or False (F).

(i) Joseph Priestley in 1770 performed a series of experiments that revealed the essential role of air in the growth of green plants.

(ii) O 2 evolved by the sulphur bacteria comes from H 2 O.

(iii) The mesophyll cells in the leaves have a large number of chloroplasts.

(iv) The membrane system is responsible for trapping the light energy and also for the synthesis of ATP and NADPH in chloroplast.

(v) The wavelength at which there is minimum absorption by chlorophyll-a, i.e. in the blue and red region shows higher rate of photosynthesis.

(vi) Chlorophyll a is the chief pigment associated with photosynthesis.

(vii) Thylakoid pigments like chlorophyll b, xanthophylls and carotenoids are accessory pigments that absorb light and transfer the energy to chlorophyll-a.

(viii) Two chlorophyll a molecules form the reaction center.

(ix)In PS-I, the reaction center chlorophyll-a has an absorption peak at 700 nm, hence is called P700, while in PS-II it has absorption maxima at 680 nm, and is called P680.

(x) The splitting of water is associated with the PS-I.
