Wrong statement during bacterial photosynthesis (A) Water gets oxidised (B) Carbon dioxide gets reduced (C) Sulphur is evolved as a by product (D) Light energy used

Assertion :- Presence of accessory pigments enhances rate of photosynthesis. Reason :- They enable a wider range of wavelength of incoming light to be utilised for photosynthesis.

Splitting of water molecules during light reaction of photosynthesis is associated with (a) PS I resulting the release of O_(2) , protons and transfer of electrons to PS II (b) PS II resulting in release of O_(2) , protons and transfer of electrons to PS I (c) PS II resulting in release of O_(2) , protons and transfer of electrons to PS II (d) PS I resulting in the release of O_(2) , protons and transfer of electrons to PS I. Of the above statements

The photochemical phase of photosynthesis includes,(a) water splitting (b) light absorption © oxygen release (d) synthesis of NADPH (e) synthesis of starch

Coordination compounds plays many important roles in animals and plants. The are essential in the storage and transport of oxygen as electrons transfer agents as catalysts and in photosynthesis Wide range of application in daily life takes place through formation of complexes Photographic fixing qualitative and quantitative analysis purification of water metallurgical extraction are some specific worth mentioning Lead poisoning in the body can be removed by (a) EDTA in the form of calcium dthydrogen salt (b) Cis-platin (c ) Zeisse' s salt (d) DMG .

Assertion: Accessory pigments enable a wider range of wavelength of incoming light to be utilised for photosynthesis. Reason: Accessory pigments also protect chlorophyll a from photo-oxidation.

A : Carotenoids protect plant from excessive heat and prevent photoxidation of chlorophyll. R : Carotenodis enable a wider range of wavelength of incoming light to be utilised for photosynthesis.
