Explanation / Answer

Ans 88 -E) with the electron transport through the chloroplast membrane , the diffusion of H+ from storma to thalakoid lumen also takes place , which results in a H+ ion concentration gradient formation.

Ans 89- A) the splitting of water will replace the electrons that has been transferred to the electron carriers of the photosystem 2. Which includes plastocynine, cytochrome b6 etc.

And 90 - C) NAD+ and FAD are the electron acceptors which takes up the electrons from photosystems and transfer to some other place wherever in need.

Ans 91- A) the photosystems leads to the formation of both ATP and NADH depending on the nature; cyclic or non-cyclic. Water is the main source of replenished electrons. So, water no electron cycle. No ATP and NADH formation.

Ans 92- D) Cohesion tension theory is the main theory which describes the movement of water. It is the combination of transportation and capillary action.

Ans 93- D) cohesion is the property by which water molecule adhere with each other and thus water transportation takes place by filling the gap in xylem created due to movement of water towards stomata
