The national curriculum framework such that children's life at school must be linked to their life outside the school. this principle marks a de portable use from the legacy of bookish learning and thus the students have been given provisions to preface some project reports on certain subjects. I express my hearty gratitude to CBSE for providing such an interesting and board scope topic for our project. I am really thankful to our respected subject teacher Mrs. Neera Sehgal who helped us in a passive way. I would also like to thank my parents and my friends for their help, encouragement and blessings.

Distribution• This distribution is somewhat similar to the one of Euphorbia Balsamifera, Pistacia Atlantica, and a few others, suggesting that a dry sclerophyl forest once covered large areas, but has been dramatically reduced due to desertification in the Sahara, leaving these few patches isolated.
• Several closely related (or sometimes identical) species can be found on the two extreme sides of the Sahara: Dragon Trees (Dracaena) and Aeonium being two of the most representative examples. 9
10
Introduction of ALOE VERA• The species was introduced to China and various parts of southern Europe in the 17th century.• The species is widely naturalised elsewhere, occurring in temperate and tropical regions of Australia, Barbados, Belize, Nigeria, Paraguay and the United States.• It has been suggested that the actual species' distribution is the result of human cultivation
11
Growing the aloe vera herb• According to botanists, Aloe Vera plants originated in warm conditions and mostly flourished in tropical and sub-tropical regions. • Africa is one of the largest homes of Aloe Vera plants. • But the plant had been carried to various parts of the world and due to its great adaptable nature, the plant flourished in any region
