Science > Biology > Applied Biology > Human Health and Diseases > Personal and Domestic Hygiene Health does not simply mean the absence of disease or physical fitness. The World Health Organization (WHO) defines health as a state of physical, mental and social well-being and not merely the absence of disease or infirmity. Thus WHO […]
Science > Biology > Botany> Morphology of Plants > The Leaf The body of a typical flowering plant can be divided into the underground root system and aerial shoot system. The shoot system is heterogeneous. The shoot system (stem) is an aerial and erect part of the plant body that grows upwards. It is usually above […]
Science > Biology > Botany> Morphology of Plants > Modification of Stem In this article, we shall study the modification in stem in some plants for performing the functions other than its primary function. Primary functions of the stem are To support and orient the leaves in a manner that they are exposed to maximum sunlight […]
Science > Biology > Botany> Morphology of Plants > The Stem and Buds The body of a typical flowering plant can be divided into the underground root system and aerial shoot system. The shoot system is heterogeneous. The shoot system (stem) is an aerial and erect part of the plant body that grows upwards. It is usually […]
Science > Biology > Botany> Morphology of Plants > Modification of Roots In this article, we shall study the modification of roots for the purpose of food storage, respiration, support, etc. Roots in some plants change their shape and structure and become modified to perform functions other than absorption and conduction of water and minerals. […]
Science > Biology > Botany > Morphology of Plants > The Root In this article, we shall study morphology of root, different regions of root, and different types of roots. Morphology: Morphology is a branch of biology dealing with the study of the form and structure of organisms and their specific structural features Importance of Morphology: […]
Science > Physics > Introduction to Measurements > Other Important Units The quantity to be measured may be very large so that the SI unit of that quantity may be smaller to use or the quantity to be measured is so small that the SI unit of that quantity is very large to use. Hence […]
Science > Physics > Introduction to Measurements > System of Units There are as many units as there are independent quantities. We consider length, mass, and time three quantities which are independent of each other. Hence they have three separate units for their measurements. Hence it is required to define systems of units. LIST OF […]
Science > Physics > Introduction to Measurements > Measurement and its Need Physics is a science of measurement. In this article, we shall study the meaning of the term ‘measurement’ and its importance in the field of science and engineering. “When you can measure what you are speaking about and express it in numbers, you […]
Science > Physics > Physics and Other Sciences LIST OF SUB-TOPICS Physics is a study of matter and energy in its different forms. In other words, physics is the study of nature and its laws. We expect that all the different events taking place in nature always take place according to some basic rules and […]
