One scientist cultured Cladophora in a suspension of Azotobacter and illuminated the culture by splitting light through a prism. He observed that bacteria accumulated mainly in the region of:

1. Violet and green light

2. Indigo and green light

3. Orange and yellow light

4. Blue and red light

Emerson's enhancement effect and Red drop have been instrumental in the discovery of:

(1) Photophosphorylation and non-cyclic electron transport

(2) Two photosystems operating simultaneously

(3) Photophosphorylation and cyclic electron transport

(4) Oxidative phosphorylation

In Hatch and Slack pathway, the primary CO₂ acceptor is -

2. Phosphoglyceric acid

3. Phosphoenol pyruvate

4. Rubisco

In photosynthesis carbon dioxide is converted to carbohydrates. It is a ......... process.

1. Reductive

2. Oxidative

3. Catabolic and exergonic

4. None of the above

Light reaction in stroma lamellae of the chloroplast results in the formation of:

1. $NADP{H}_2$

2. $ATP+NADP{H}_2$

3. ATP

4. $O_2$

Kranz anatomy can be observed in leaves of:

1. sorghum
