Given below are two statements: Statement I: In C_3 plants, some...

Given below are two statements: Statement I: In C3\mathrm{C}_3 plants, some O2\mathrm{O}_2 binds to RuBisCO, hence CO2\mathrm{CO}_2 fixation is decreased. Statement II: In C4\mathrm{C}_4 plants, mesophyll cells show very little photorespiration while bundle sheath cells do not show photorespiration. In the light of the above statements, choose the correct answer from the options given below:

Options

  1. ABoth Statement I and Statement II are false
  2. BStatement I is true but Statement II is false
  3. CStatement I is false but Statement II is true
  4. DBoth Statement I and Statement II are true

Correct answer

B. Statement I is true but Statement II is false

Step-by-step solution

In C3\mathrm{C}_3 plant, some O2\mathrm{O}_2 bind to RuBisCO, and hence CO2\mathrm{CO}_2 fixation is decreased. Statement II is incorrect, photorespiration does not occur in C4\mathrm{C}_4 plants as they lack RuBisCO in mesophyll. Hence statement I is the only correct option.
