1. | described a first action spectrum of photosynthesis |
2. | provided evidence for production of glucose when plants grow |
3. | showed that it is only the green parts of the plant that can release oxygen |
4. | first showed that oxygen evolved by the green plant comes from water, not from carbon dioxide |
1. | only PS I is functional |
2. | both photosystems work in series, first PS I and then PS II |
3. | only ATP synthesis takes place and NADPH is not synthesized |
4. | both ATP and NADPH are synthesized |
1. | Calvin cycle takes place in Mesophyll cells |
2. | Initial carboxylation reaction occurs in Bundle sheath cells |
3. | Number of carbon atoms in the primary carbon dioxide acceptor is 3 |
4. | PGA is the primary carbon dioxide fixation product |
1. | PS I | 2. | PS II |
3. | Both 1 and 2 | 4. | Neither 1 nor 2 |
1. | Reduction of NADP to NADPH2 on the stroma side of the membrane |
2. | Breakdown of proton gradient |
3. | Breakdown of electron gradient |
4. | Movement of protons across the membrane to the stroma |
Statement I: | \(CO_2\) acceptor in \(C_4\) plants is phosphoenolpyruvate and is found in the mesophyll cells. | The primary
Statement II: | \(C_4\) plants lack RuBisCO enzyme. | Mesophyll cells in
What is the role of large bundle sheath cells found around the vascular bundles in C4 plants?
1. | To protect the vascular tissue from high light intensity. |
2. | To provide the site for photorespiratory pathway. |
3. | To increase the number of chloroplast for the operation of Calvin cycle. |
4. | To enable the plant to tolerate high temperature. |
The products of light reaction in photosynthesis are:
1. ATP, NADPH and \(\text{O}_2\)
2. ATP, NADPH, \(\text{O}_2\) and \(\text{H}_2 \text{O}\)
3. ATP, NADPH and \(\text{H}_2 \text{O}\)
4. ATP, NADPH and \(\text{CO}_2\)
