CHEMICAL COORDINATION AND INTEGRATION IN LIVING ORGANISMS
CHEMICAL COORDINATION AND INTEGRATION https://www.facebook.com/sciencegajab/ visit for fb page CHEMICAL COORDINATION AND INTEGRATION IN LIVING ORGANISMS ARE PRIMARILY DONE BY ENDOCRINE GLANDS HORMONES ARE • Non-nutrients chemicals • Intercellular messengers • Produced in trace amount. • Generally endocrine gland secretions are Hormones but some chemicals also considered as hormones which are not produced by endocrine glands. […]
NEURAL CONTROL AND COORDINATION
NEURAL CONTROL AND COORDINATION 1. The neural system Function –> coordinates and integrates @ To maintain Homoeostasis therefore it is called neural control and coordination. 2. The neural system and the endocrine system jointly coordinate and integrate all the activities of the organs –> in a synchronised fashion. 3. The neural system –> An organised […]
PHOTOSYNTHESIS IN HIGHER Plants
PHOTOSYNTHESIS IN HIGHER Plants 1. PHOTOSYNTHESIS IS A PHYSIO-CHEMICAL PROCESS by which green plants use light energy to drive the synthesis of organic compounds. 2. PHOTOSYNTHESIS IS IMPORTANT DUE TO TWO REASONS: o it is the primary source of all food on earth and o it is also responsible for the release of […]
MINERAL NUTRITION IN PLANTS | CRITERIA FOR ESSENTIALITY |MACRONUTRIENTS |MICRONUTRIENTS |DEFICIENCY SYMPTOMS OF ESSENTIAL ELEMENTS |TOXICITY OF MICRONUTRIENTS |NITROGEN METABOLISM |
MINERAL NUTRITION 1. IN 1860, JULIUS VON SACHS (GERMAN BOTANIST) –> Demonstrated, for the first time, that plants could be grown to maturity in a defined nutrient solution in complete absence of soil. 2. THIS TECHNIQUE OF GROWING PLANTS IN A NUTRIENT SOLUTION IS KNOWN AS HYDROPONICS. 3. Through hydroponics technique, impact of a specific minerals […]

MOLECULAR BASIS OF INHERITANCE. NCERT Based & Simplified 1. Finding out the chemical responsible for Mendelian inheritance (factor), its structure,& How it works is MOLECULAR BASIS OF INHERITANCE. 2. DNA act as genetic material in all cellular organism either it is prokaryotic or eukaryotic. o RNA ACT AS GENETIC MATERIAL ONLY IN SOME VIRUSES. o […]

ENVIRONMENTAL ISSUES 1.Growing human population –> Exerting tremendous pressure on natural resources, pollution of air, water and soil. 2. POLLUTION is any undesirable change in physical, chemical or biological characteristics of air, land, water or soil. 3. Agents that bring about such an undesirable change are called as POLLUTANTS. 4. Environment (Protection) Act, 1986 to control environmental […]
