Question

Explain the process of photosynthesis ?​

Answer 1

Photosynthesis

Photosynthesis is a process by which green plants prepare food ( carbohydrates , glucose , starch , etc. ) in presence of sunlight and chlorophyll  where water and carbon dioxide are the reactants and oxygen is another by-product obtained .

Explanation

▶ The plants take in carbon dioxide through the opening of stomata . Stomata opens due to the active transport of potassium ions inside it which leads to osmosis or entry of water within the guard cell . The guard cells of stomata become turgid and hence carbon dioxide easily diffuses in .

▶ The water enters the plant through the soil . This takes place also due to the process of endosmosis .

▶ There are two phases : light dependent phase and the light independent phase . Chlorophyll and light is necessary for the light dependent phase .

Reaction

$6CO_2+6H_2O\rightarrow C_6H_{12}O_6+6O_2$

$<b>__________________________________________</b>$

Photosynthesis (Photon = Light, Synthesis = Putting together) is an anabolic, endergonic process by which green plant synthesize carbohydrates (initially glucose) requiring carbon dioxide, water, pigments and sunlight. In other words, we can say that photosynthesis is transformation of solar energy/radiant energy/light energy (ultimate source of energy for all living organisms) into chemical energy.

According to Van Neil and Robert Hill, oxygen liberated during photosynthesis comes from water and not from carbon dioxide.

Thus, the overall correct biochemical reaction for photosynthesis can be written as:

$\sf 6 CO _2 + 12 H_2 O \to C_6H_{12}O _6 + 6O _2 + 6H_{2}O$

Some photosynthetic bacteria use hydrogen donor other than water. Therefore, photosynthesis is also defined as the anabolic process of manufacture of organic compounds inside the chlorophyll containing cells from carbon dioxide and hydrogen donor with the help of radiant energy.

$\rm{\large{Significance \: of \: Photosynthesis:}}$

1. Photosynthesis is the most important natural process which sustains life on earth.

2. The process of photosynthesis is unique to green and other autotrophic plants. It synthesizes organic food from inorganic raw materials.

3. All animals and heterotrophic plants depend upon the green plants for their organic food, and therefore, the green plants are called producers, while all other organisms are known as consumers.

4. Photosynthesis converts radiant or solar energy into chemical energy. The same gets stored in the organic food as bonds between different atoms. Photosynthetic products provide energy to all organisms to carry out their life activities (all life is bottled sunshine).

5. Coal, petroleum and natural gas are fossil fuels which have been produced by the application of heat and compression on the past plant and animal parts (all formed by photosynthesis) in the deeper layers of the earth. These are extremely important source of energy.
