TREE THAT RELEASES OXYGEN ROUND THE CLOCK

Usually plants take CO2 and release oxygen during day (due to photosynthesis) and they take O2 and release carbon dioxide during night as a result of respiration. But it has been found that Peepal tree (scientific name Ficus religiosa) releases oxygen 24 hours a day. How is it possible that a plant releases oxygen throughout […]

PHOTOSYNTHESIS

Photosynthesis is a process by which plant prepare their food from carbon dioxide and water with the help of sunlight in the presence of chlorophyll. About 90% of photosynthesis is carried out by aquatic plants. Word ‘Photosynthesis’ comprises of two words ‘photo’ & ‘synthesis. Photo means light and synthesis means preparation. Thus photosynthesis is a […]

NUTRITION IN GREEN PLANTS

Green plants prepare their own organic food (starch) from inorganic sources by the process of photosynthesis. They are autotrophic in nature Photosynthesis: photo – light; synthesis = putting together. It is the process of conversion light energy into chemical energy in which the inorganic components like carbon dioxide and water (CO2 and H2O) are utilised […]
