Herbicide that blocks electron transport from PS-II to PS-I by inhibiting electron flow between plastoquinone cytochrome is

Options

  1. ADCMU
  2. BParaquat
  3. CDCPIP
  4. DNone of these

Correct answer

A. DCMU

Step-by-step solution

DCMU is selective herbicide that acts as a potent inhibitor of PS-II. Paraquat inhibits PS-I by producing super oxides. DCPIP is a dye used to measure rate of photosynthesis.
