8. Deep in the ocean, sunlight can hardly reach, yet plants such as brown and red algae are found here. How do you think they are able to synthesize their food?

9. Can plants use an artificial source of light (for example, tube light) for preparing food?



Answer :

GinnyAnswer

Final answer:

Red algae use phycoerythrin to conduct photosynthesis in deep ocean areas. Artificial light such as tube lights cannot be used by plants for preparing food.


Explanation:

Red algae are able to synthesize their food deep in the ocean by utilizing phycoerythrin, a pigment in their chloroplasts that absorbs blue light, as red light doesn't reach those depths. This allows them to conduct photosynthesis using available blue light.

Plants can not use artificial light sources like tube lights for photosynthesis as these lights do not provide the specific wavelengths and intensity of light needed for the process.
