Statement A : The single chlorophyll a molecule forms the reaction centre Statement B : In PS I the reaction centre has an absorption peak at 680 nm and in PS II has absorption maxima at 700 nm
1 Statement-A is correct but Statement-B is incorrect
2 Statement-A is incorrect but Statement-B is correct
3 Both the statements are correct
4 Both the statements are incorrect
Explanation:
The single chlorophyll a molecule forms the reaction centre. The reaction centre is different in both the photosystems. In PS I the reaction centre chlorophyll a has an absorption peak at 700 nm, hence is called P700, while in PS II it has absorption maxima at 680 nm, and is called P680.

Light Harvesting complexes (LHCs) are
1 Present within PS-I and PS-II
2 Huge no.of chlorphyll-a
3 Hundreds of pigment molecules bound to proteins
4 1 and 3
Explanation:
The pigments are organised into two discrete photochemical light harvesting complexes (LHC) within the Photosystem I (PS I) and Photosystem II (PS II). The LHC are made up of hundreds of pigment molecules bound to proteins. Each photosystem has all the pigments (except one molecule of chlorophyll a) forming a light harvesting system also called antennae.

Which of the following is incorrect about photosystem?
1 In PS I the reaction centre chlorophyll a has an absorption peak at 700 nm, hence is called P700
2 PS I and PS II are named in sequence of their discovery.
3 LHC is made up of hundred of pigment molecules which are bounded proteins.
4 Each photosystem has all the pigments along with alot of chlorophyll - a
Explanation:
Each photosystem has all the pigments, with alot of accessory pigments and only one chlorophyll-a as reaction centre.
