  Introduction to Nutrition in PlantsLiving and Non-Living  OrganismsLiving organisms like human beings, plants and animals need food to survive and exist.Living organisms reproduce, respond to the environment and also adapt.Living organisms respire and excrete as well.Cells Cells are tiny units that help make up a living organism. Hence, they are also called building blocks of an organism. A cell is constituted of three major parts :A thin outer layer called the cell membrane.A spherical structure located at the centre of the cell called a nucleus.A jelly-like substance that surrounds a nucleus called the cytoplasm. To know more about Cell, visit here. Single and Multi-Cellular OrganismsOrganisms that are made up of just one cell are called single-celled or Unicellular organisms. E.g.  AmoebaOrganisms with more than one cell in their body are called multicellular organisms.All human beings, plants and animals are multicellular organisms. To know the difference between Unicellular and

1 vitamins and minerals are essential components of food, these components are called nutrients Humans and animals are dependent directly or indirectly on plants for food Nutrition is the mode of taking food by an organism and its utilisation by the body Green plants are called autotrophs as they prepare their own food from simple substances Animals and most other organisms are called heterotrophs as they take in ready-made food prepared by the plants The synthesis of food in plants occurs in leavesPhotosynthesis can be carried out in presence of chlorophyll, sunlight, carbon dioxide, and water Complex chemical substances like carbohydrates are the products of photosynthesis Pitcher plants and Venus flytraps are insectivorous plantsFungi derive nutrition from dead and decaying matters they are called saprotrophs Q1: Name some components of food. View Answer Q2: Define nutrients. View Answer Q3: Give an example of autotrophs. View Answer Q4: Give an example of heterotrophs. View Answer

  Vikram Sarabhai, The Man Who Actualised The Space Dream Of Billion Of Indians Since its inception, the Indian Space Research Organisation (ISRO) has given every Indian innumerable milestones to be proud of. ISRO was institutionalised in 1969 and since then, it has never failed to achieve its vision to 'harness space technology for national development. ISRO After its establishment, the Indian Space Research Organisation (ISRO) set many milestones, but did you know about  the young man, who initiated India's space research and helped develop nuclear power in the country. Today we share an  inspiring story  of Dr. Vikram Ambalal Sarabhai - known as the father of the Indian space program (ISRO).  In 1962, Vikram Sarabhai was given Isro's charge and worked for a token salary of one rupee in view of his personal wealth. Who was Vikram Sarabhai? Vikram Sarabhai: The father of Indian Space Programme | Twitter One of India's most admired scientists Vikram Sarabhai, in full Vi

 Laziness is making your bones weak; healthy diet with milk, eggs & nuts will help Do you have a history of multiple fractures? Do you find it difficult to stand or be active for long hours? Is there a general feeling of malaise, and weakness? It's time to get tested for osteoporosis. Osteoporosis means the deterioration of bone density - the term originated from 'osteo' meaning bone and 'porosis' meaning decreased density or porosity. It is a significant medical concern, which increases fracture risk, morbidity, mortality and even loss of active years. An estimated 200 million suffer from osteoporosis. The condition affects the higher age-group the most - mostly people at the age of 60 and above. In this elderly age group, post-menopausal women have a higher incidence of osteoporosis than males. What causes osteoporosis? Healthy bone requires a titration in gain and loss of calcium that is dependent on diet, hormonal balance and physical activity. Any alteratio

  Important Questions for Class 12 Physics Chapter 2 Electrostatic Potential and Capacitance Class 12 Important Questions Electrostatic Potential and Capacitance Class 12 Important Questions Very Short Answer Type Question 1. A 500 µC charge is at the centre of a square of side 10 cm. Find the work done in moving a charge of 10 µC between two diagonally opposite points on the square. (Delhi 2008) Answer: The work done in moving a charge of 10 µC between two diagonally opposite points on the square will be zero because these two points will be at equipotential. Question 2. What is the electrostatic potential due to an electric dipole at an equatorial point? (All India 2009) Answer: Electric potential at any point in the equatorial plane of dipole is Zero. Question 3. What is the work done in moving a test charge q through a distance of 1 cm along the equatorial axis of an electric dipole? (All India 2009) Answer: Since potential for equatorial axis V = 0 ∴ W = qV = 0 Question 4. Define
