Answer: (d)
Related Facts:
- According to a report published in Science magazine, scientists have achieved success in discovery of a new type of photosynthesis.
- This discovery was led by Imperial College London.
- During the research study new chlorophyll was also discovered.
- This new chlorophyll is known as Chlorophyll F.
- This new chlorophyll works near infrared light in similar manner as chlorophyll A works in sunlight.
- Chlorophyll that is used by vast majority of plants in visible red light during the process of photosynthesis is known as chlorophyll A.
- This came to know when a wide range of cyanobacteria (blue-green algae) grow near-infrared light on the rocks along the seashore in Australia and found in shaded conditions.
- Now, as discovered it also occurs in a cupboard fitted with infrared LEDs in Imperial College London.
- The process of changing of light energy in to the chemical energy is called photosynthesis.
- Plants make food in their leaves. The leavescontain a pigment called chlorophyll, which colors the leaves
- In the presence of sunlight, carbohydrate is formed before the formation of carbon dioxide and water.
- After that formation of other organic substance like proteins, cellulose, enzymes etc. in plants takes place.
- Through the process of photosynthesis carbon dioxide is absorb and oxygen is released by plants.
