Photolysis or photoionization is the splitting of water into protons, electrons and oxygen in presence of light.

Hormone regulates metabolism, growth as well as the development of our organs, endocrine organs and the cells.

A C₃ plant is one in which the first stable compound obtained during the dark reaction is a three-carbon compound.

Sella tursica.

Synthesis of ATP in the presence of light is called Photophosphorylation.

Quantasomes is a functional unit (photosynthetic units) made of a group of pigment molecules required for carrying out a photochemical reaction.

Quantasome is a functional unit (Photo-synthetic unit) made of a group of pigment molecules required for carrying out a photochemical reaction. The Pigment molecules are embedded in the grana and differentiated as pigment system I (with chi 670, chi 680, P 700) and pigment system ll(with chi 670, chi 680, P 680 and Xanthophylls)

The height of troposphere from the sea level is 0 to 12 km.

Amrita Devi of Bishnoi society first gave her life for protecting the trees.

 Earth Day celebrated on April 22.

Protection from cosmic rays and UV rays.

Refrigeration industry.

Percentage of CO₂ in the air is 0.03%.

When the Ozone day is celebrated 16 September.

1. Increase in the green house will increase global temperature. It will cause heavy rains and flood in coastal regions and droughts in average rainfall regions. It is reported that if the temperature continues to rise than it will increase by 3.6°C upto 2100. It will lead to drought, cyclones, hurricane, flood, epidemics and may lead to final destruction of the Universe.
2. The green house effect will decrease production of agricultural products and fish production in India and other developing countries.
3. The sea level will rise due to melting of polar ice because of increased temperature. As a result, the coastal regions will be merged under sea water.

• CFC (Chloro Floro Carbon), CBC (Chloro Bromo Carbon) and BFC (Bromo Floro Carbon). These compounds are collectively called as Freon and they are highly volatile organic compounds. They are used in refrigeration industries, Aerosols, formation of foam, cleaning of many industrial machines etc. The CFC compounds release Chlorine radicals which re-main active for about two years and destroy 1 lakh molecules of Ozone by chain reaction.
  CFCl₃ → CF CL₂ +Cl
  Cl + O₃ → ClO + O₂
  ClO + O₃ → 2O₂ + Cl
• Nitrogen Oxides (NO—Nitric Oxide, N₂O—Nitrous oxide)—They are released mainly by the chemical fertilizers and they destroy the Ozone.
• Jet Aeroplanes – Most of the jet aeroplanes prefer to fly in/close to the stratosphere. The jet of air and other pollutants released by them harm the Ozone.
• Nuclear blasts also harm the Ozone.
• Deforestation is also a major cause of Ozone depletion.
• Sulphur oxides (SO₂, SO₃) and Hydrochloric acid (HCl).

The main green house gas is CO₂.

Rain water with acid like H₂SO₄, HNO₃ etc.

Skin cancer, Cataract, Reduced production of rice etc.

Green house effect can be controlled b reducing the formation of green house gases such as CO₂, Methane. Troposphere O₃ etc.

Increase of CO₂ in the atmosphere causing green house effect. As a result the atmospheric average temperature is increasing. It is called as global warming.

The sea currents that cause fluctuations in water also affect the environment. One of them is El Nino effect. It is caused by the warming of the pacific ocean near the equator, off the coast of South America.
