NEETBotanyPhotosynthesis in Higher Plants
Read the following Assertion and Reason and choose the correct option. Assertion: In photosystem II electrons become excited Reason: PS II has absorption maxima at 680 nm, and is called P680
Options
- ABoth Assertion and Reason are true and Reason is correct explanation of Assertion
- BBoth Assertion and Reason are true but Reason is not the correct explanation of Assertion
- CAssertion is true but the Reason is false
- DBoth Assertion and Reason are false
Correct answer
A. Both Assertion and Reason are true and Reason is correct explanation of Assertion
Step-by-step solution
In photosystem II the reaction centre chlorophyll a absorbs 680 nm wavelength of red light causing electrons to become excited and jump into an orbit farther from the atomic nucleus.
