Question

Write the significance of photosynthesis

Answer 1

Green plants absorb carbon dioxide from air and water from the soil. In the presence of sunlight and chlorophyll they synthesize starch as food. They release oxygen as a by-product. Hence, photosynthesis provides food for most of the living organisms present on earth.

Answer 2

The primary function of photosynthesis is to convert solar energy into chemical energy and then store that chemical energy for future use. For the most part, the planet’s living systems are powered by this process. It’s not particularly efficient by human engineering standards, but it does the job. Photosynthesis happens in regions of a cell called chloroplasts. The chemistry and physics are complex.

It’s a bit humbling to consider that the energy in our bodies travels 93 million miles in a little more than eight minutes, and that life has tapped into that energy stream. For a short time that energy is tied up in biological systems before it continues on its merry way into the dark of space.
