The given diagram shows a series of experiments performed by Priestley. Identify the hypothesis given by Priestley?
1 Plants restore to the air whatever breathing animals and burning candles remove
2 It is only the green part of the plants that could release oxygen
3 Sunlight is essential to the plant process
4 All the above
Explanation:
Priestley hypothesised that plants restore to the air whatever breathing animals and burning candles remove. Ingenhousz showed that sunlight is essential for plant process. He also found that only green parts of the plants could release oxygen.

1 Cladophora , blue green algae is used.
2 Prism was used to split light into its spectral component.
3 Bacteria accumulated mainly in the region of blue and red light
4 The aerobic bacteria were used to detect the sites of \({O_2}\) evolution.

Photosynthesis is the fastest in
1 Blue light
2 Intermittent white light
3 Red light
4 Green light
Explanation:
As far as the rate of photosynthesis is concerned, it is fastest in white light making the rate of photosynthesis maximum. Photosynthesis occurs highest in the shortest wavelength hence has the max energy. Photosynthetic pigments absorb visible part of the radiation (i.e., 380 um and 760 um). For example, chlorophyll absorbs blue and red light. Usually, plants show a high rate of photosynthesis in the blue and red light. Maximum photosynthesis has been observed in red light than in blue light. The green light has a minimum effect. The rate of photosynthesis is maximum in white light or sunlight( Polychromatic light). On the other hand, red algae show maximum photosynthesis in green light and brown algae in blue light.
