What is the role of large bundle shealth cells found around the vascular bundles in C 4 plants?

To increase the number of chloroplast for the operation of Calvin cycle

To enable the plant to tolerate high temperature

To protect the vascular tissue from high light intensity

To provide the site for photorespiratory pathway

Which one of the following is not true regarding the release of energy during ATP synthesis through chemiosmosis? It involves:

Movement of protons across the membrane to the stroma

Reduction of NADP to NADPH 2 on the stroma side of the membrane

Given below are two statements: Statement I: The primary CO 2 acceptor in C 4 plants is phosphoenolpyruvate which is found in the mesophyll cells. Statement II: Mesophyll cells of C 4 plants lack RuBisCo enzyme. In light of the above statements, choose the correct answer from the options given below:

Both Statement I and Statement II are correct

Both Statement I and Statement II are incorrect

Statement I is correct but Statement II is incorrect

Statement I is incorrect but Statement II is correct

Which of the following statements is incorrect?

Cyclic photophosphorylation involves both PS I and PS II.

Both ATP and NADPH + H + are synthesized during non-cyclic photophosphorylation.

Stroma lamellae have PS I only and lack NADP reductase.

Grana lamellae have both PS I and PS II.

Which of the following statements is incorrect?

In C 4 plants, the site of RuBisCO activity is mesophyll cell

RuBisCO is a bifunctional enzyme

The substrate molecule for RuBisCO activity is a 5 - carbon compound

RuBisCO action requires ATP and NADPH
