Question

Name the part of the plant which produces its food. Name this process.

Answer 1

Hint: To us, plants are very important. The food people consume comes from plants directly or indirectly. So all of the food we eat comes from plants. But what are plants eating? They're making food of their own!

Complete Answer:
To make their own food, plants need many things.
They're in need of:
- Chlorophyll, a green pigment present in plant leaves
- Light (like from a light bulb, either natural sunlight or artificial light)
- Carbon dioxide ( CO2)-(a gas present in the air; one of the gases that humans and animals breathe out as they exhale).
- The water (which is obtained by the plant through its roots).
- Nutrients and minerals (through which the plant gathers from the soil through its roots.
- Plants use their leaves to create food. The leaves contain a pigment that colours the leaves green, called chlorophyll. Chlorophyll can create food from carbon dioxide , water, nutrients, and energy from sunlight that can be used by the plant. Photosynthesis is called this process.
- During the photosynthesis procedure, plants release oxygen into the air. To breathe, humans and animals require oxygen.
- Light energy is absorbed and used to convert water, carbon dioxide , and minerals into oxygen and energy-rich organic compounds during photosynthesis in green plants.
- The value of photosynthesis in the preservation of life on Earth would be difficult to overestimate. There will soon be no food or other organic matter on Earth if photosynthesis stopped. The majority of life would die, and the Earth's atmosphere would become almost devoid of gaseous oxygen over time.
- Chemosynthetic bacteria, which are able to use the chemical energy of certain inorganic compounds and are therefore not dependent on the conversion of light energy, will be the only species able to survive under such conditions.

Note: The fossil fuels (i.e. coal, oil , and gas) that power industrial civilization are responsible for the energy generated by photosynthesis carried out by plants millions of years ago.
