Photosynthesis

Yes, it is correct. Light-dependent reactions or light reactions capture the energy of light and use it to make the energy-storage molecules ATP and NADPH.

Yes, it is the correct answer. Photosynthesis occurs in two stages. In cellular respiration, glucose and other compounds are oxidized to produce carbon dioxide, water and release chemical energy. Here carbon dioxide is converted into carbohydrate.

The chloroplast is enclosed by a membrane. This membrane is composed of a phospholipid inner membrane, a phospholipid outer membrane, and an intermembrane space between them. Within the membrane is an aqueous fluid called the stroma.

Yes, it is correct. Phycocyanin, carotenes and xanthophylls in green algae, phycoerythrin in red algae (rhodophytes) and fucoxanthol in brown algae.

Yes, both 1 and 2 are correct. In both the processes carbon is converted into sugar.

Yes, it is correct. The surface of the leaf is uniformly coated with a water resistant waxy cuticle that protects the leaf from excessive evaporation of water and decreases the absorption of ultraviolet or blue light to reduce heating.

Yes, it is correct. Plants absorb light primarily using the pigment chlorophyll, the pigment is embedded in plants and algae in special antenna-proteins. In such proteins all the pigments are ordered to work together. Such a protein is also called a light harvesting complex.

Yes, it is correct. This whole scheme of transfer of electrons, starting from the PS II, uphill to the accepter, down the electron transport chain to PS I, excitation of electrons, transfer to another accepter, and finally down hill to NADP⁺ causing it to be reduced to NADPH+H⁺ is called the Z scheme.

Yes, it is the correct answer, as it does not belong to C3 group. It has no distinct bundle sheath, one type of chloroplasts.

The LHC is made up of hundreds of pigment molecules bound to proteins. The single chlorophyll molecule forms the reaction centre. The reaction centre is different in both the photosystems. In PS I the reaction centre 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.

Yes, it is correct. Calvin and his co-workers worked out the whole pathway and showed that the pathway operated in a cyclic manner; the RuBP (Ribulose bisphosphate) was regenerated. The Calvin cycle can be described under three stages: carboxylation, reduction and regeneration.

Yes, it is correct. Living organisms have the capability of extracting energy from oxidisable substances and store this in the form of bond energy. ATP, carry this energy in their chemical bonds. In phosphorylation ATP is synthesised by cells in mitochondria and chloroplasts.

Yes, it is the correct answer. This plant shows Kranz anatomy and hence, it belongs to C4 group of plants.

Yes, it is correct. Algae also use chlorophyll, but various other pigments are present as phycocyanin, carotenes and xanthophylls in green algae, phycoerythrin in red algae (rhodophytes) and fucoxanthol in brown algae and diatoms resulting in a wide variety of colours.

Yes, it is correct. Light reactions or the ‘Photochemical’ phase includes light absorption, water splitting, oxygen release, and the formation of high-energy chemical intermediates, ATP and NADPH.
