Here A and B refer to

If only chlorophyll a were present in plants, which phenomenon would be most prominently observed?

Photosynthesis is a

Read the following statements and select the correct ones

(i) PS I is involved in non – cyclic photophosphorylation only

(ii) PS II is involved in both cyclic and non –cyclic photophosphorylation

(iii) Stroma lamellae membranes possess PS I only whereas grana lamellae membranes possess both PS I and PS II

Electrons are transferred by splitting of ${H_2}O$ through ETC during light reaction and reduces

Photophosphorylation differs from oxidative phosphorylation in requiring input of energy in the from of

I. The electrons that carriers photophosphorylation are located in the thylakoid membrane

II. During photophosphorylation, the chloroplast stroma becomes more acidic than the interior of thylakoid membrane

III. Protons diffuses through the protein channels which are ATP synthetase molecules

IV. ATP is formed from ADP + Pi on the stroma side of the thylakoid in the chloroplast

V. During photophosphorylation, water ionises to form ${H^ + }$, yielding electrons to PS-II

Which of the following statement are false?

A graph that plots the rate at which $C{O_2}$ is converted to glucose versus the wavelength of light illuminating a leaf is called

Given below are two statements:

Statement I: The primary $CO_2$ acceptor in $C_4$ plants is phosphoenolpyruvate and is found in the mesophyll cells.

Statement II: Mesophyll cells of $C_4$ plants lack RuBisCo enzyme
