Ozone day 16th September Ozone day is an international observance that aims to raise awareness about the importance of protecting the ozone layer, which shields the Earth from harmful ultraviolet radiation. The United Nations General Assembly designated September 16 as the International Day for the Preservation of the Ozone Layer, commemorating the date of the signing of the Montreal Protocol on Substances that Deplete the Ozone Layer in 1987. On this day, various events and activities are organized around the world to educate people about the causes and consequences of ozone depletion, and to encourage them to take action to prevent further damage to the ozone layer. Some of these activities include seminars, workshops, exhibitions, quizzes, competitions, tree planting, and media campaigns. Ozone day is also an opportunity to celebrate the achievements of the Montreal Protocol and its amendments, which have successfully phased out nearly 100% of ozone-depleting substances and contribu

   INTRODUCTION TO HORTICULTURE  The term ‘Horticulture’ is derived from two Latin words, where hortus means Garden and cultura means Cultivation. The word horticulture came into existence in the seventeenth century. It is found mentioned in Peter Laurenberg’s treatise written in 1631 however ‘E. Phillips Miller’ used the word horticulture in his book “The New World of English Word” in 1678.                In ancient days the gardens had protected enclosures with high walls or similar structures surrounding the houses. The enclosed places were used to grow fruit, vegetables, flowers and ornamental plants. The garden crops include fruits, vegetables, flowers, ornamental tree, spices, plantations, medicinal and aromatic plants. The products of horticultural crops such as fruits and vegetables are easily perishable so that they are utilized in the fresh state.               “At present the horticulture may be defined as the science and technique of production, processing and merchand

 Root Morphology of Flowering Plants • Morphology is the name given to the science that deals with the study of the form and structure of things. No matter which plant you take, the morphology of a flowering plant includes the roots, stem, leaves, flowers, and fruits. Flowering Plants • Flowering plants are the most diverse group of land plants with 300,000 known species. • These are also known as angiosperms and produce seed-bearing fruits. •  It is believed that the flowering plant evolved from gymnosperms during the Triassic period and the first flowering plant emerged 140 million years ago. • Flowers are the reproductive organs of the flowering plants and the most important feature that distinguishes them from other seed plants. • The flowering plants reproduce by the process of pollination. In this, the pollen grains transfer from the anther of the male flowers to the stigma of the female flower where fertilization occurs and seed is formed. • A plant has two systems: Root syste

 MENDEL’S LAWS OF INHERITANCE AND EXCEPTIONS TO THE LAWS  History :- The assertion that life can instantaneously arise from non living matter is called spontaneous generation. Here are the critical experiments that busted the myth. Although today we understand that living things arise from other living things, the idea of spontaneous generation was entrenched in the minds of man throughout most of history. Spontaneous generation is the belief that, on a daily basis, living things arise from non living material. This debunked belief is not the same as abiogenesis, the study of how life on earth could have arisen from inanimate matter billions of years ago.  Aristotle and Spontaneous Generation (383-322)  Aristotle was one of the first to record his conclusions on the possible routes to life. He saw beings as arising in one of three ways, from sexual reproduction, asexual reproduction or nonliving matter. According to Aristotle, it was readily observable that aphids arise from the dew on
