Select the correct matching of the characteristics in respect of ${\mathrm{C}}_3$ and ${\mathrm{C}}_4$ plants.

	Characteristic	${\mathrm{C}}_3$ plant	${\mathrm{C}}_4$ plant
A	Primary ${\mathrm{CO}}_2$ acceptor	RuBP	PEP
B	Occurrence of Rubisco	Bundle sheath	Mesophyll
C	Primary ${\mathrm{CO}}_2$ fixation product	PGA	OAA
D	Number of $\mathrm{ATP} \& \mathrm{NADPH}·{\mathrm{H}}^{+}$ required for the synthesis of 1 molecule of glucose	18 & 12	30 & 12

 

Study the pathway given below ${\mathrm{C}}_4$ cycle diagram.

In which of the following options are correct words for all the three blanks A, B, and C are indicated?

Read the following statements carefully.

(a) Photorespiration protects the plant from photo-oxidative damage by dissipating excess excitation energy.
(b) Above $40°\mathrm{C}$ the rate of respiration becomes high.
(c) Substrate level phosphorylation generates 8 ATP in glycolysis.
(d) Retting of stem fibres is carried out with the help of bacterial fermentation of softer tissues.

Pick up the correct statements.
