                                                        Self Motivation             M otivation is  the process that initiates, guides, and maintains goal-oriented behaviours . It is what helps you lose extra weight, for instance, or pushes you to get that promotion at work. In short, motivation causes you to act in a way that gets you closer to your goals.                                                       Motivational Quotes “All our dreams can come true, if we have the courage to pursue them.”  — Walt Disney “The secret of getting ahead is getting started.”  — Mark Twain “I’ve missed more than 9,000 shots in my career. I’ve lost almost 300 games. 26 times I’ve been t...

MECHANISMS OF NUTRIENT UPTAKE In plants, nutrients are absorbed mainly by the roots and must get contact with root surface. However, the structural complexity of root epiblema is the main barrier for entry of nutrients into cortex.  Nutrients are not absorbed uniformly throughout roots as roots have three different regions viz. root hairy, elongation and meristematic zones, and radioactive studies showed that meristematic zone resulted in more nutrients uptake than others. Plants are also capable to absorb nutrients through aerial parts via stomata and cuticle. In order for mineral nutrients to be taken up by a plant, they must enter the root by crossing the plasma membranes of root cells. From there they can be transported through the symplast tothe interior of the root and eventually find their way into the rest of the plant.  Within the soil nutrient can move to the root surface both by bulk flow and by diffusion.  Mechanism of absorption Absorption of ions by plants r...

Crop :-  It is a group of plants grown as a community in a specific locality and, for a specific Purpose. Crop Physiology:- Crop physiology is the study of the ways in which plant physiological processes are integrated to cause whole plant responses in communities. The subject matter of crop   physiology includes the ways in which the knowledge of plant physiology is applied for   better management of crops . Plant physiology is a study of Vital phenomena in plant. It is the science concerned   with Processes and functions, the responses of plants to environment and the growth and   development that results from the responses.  Essentially the overall goal of plant physiology is to evolve a detailed and comprehensive knowledge of all the natural phenomena that occur in living plants and thus   to understand the nature of plant growth, development and productivity. Many aspects of practical agriculture can benefit from more intensive research in pl...

 INSECT DEFINITION : • Insect the word is derived from latin insectum meaning " cut into section " • insects are the largest group of invertebrate within the arthopoda phylum that have a chitinous exoskeleton a three part body ( head ,thorax and abdomen) three pairs of jointed legs, compound eyes and one pair of antennae.  • They are among the most diverse groups of animals on the planet, including more than a million described species and representing more than half of all know living organism. Characters of Class: Insecta • Bilaterally symmetrical. • Body covered by chitinous exoskeleton which is periodically shed and renewed. • Body divisible into Head, Thorax and Abdomen. • One pair of antenna, two pairs of wings and three pairs of legs. • Appendages are paired and segmented. • Tubular alimentary canal. • Open circulatory system (body cavity is blood cavity called haemocoel). • Excretion is by tubes (Malpighian tubules)  • Respiration by trachea or gills. • Decentral...

1. Why Soil and water conservation:- Soil and water are two important natural resources and the basic needs for agricultural production. During the last century it has been observed that the pressure of increasing population has led to degradation of these natural resources. In other words increase in agricultural production to feed the increasing population is only possible if there sufficient fertile land and water are available for farming. In India, out of 328 million hectares of geographical area, 68 million hectares are critically degraded while 107 million hectares are severely eroded. That's why soil and water should be given first priority from the conservation point of view and appropriate methods should be used to ensure their sustainability and future availability. Fig. 1.1. Global soil degradation map. (Source: UNEP, International Soil Reference and Information Centre (ISRIC), World Atlas of Desertification, 1997) Water conservation is the use and management of water f...

∆    Asexual Reproduction In fungi asexual reproduction is a more common method than sexual reproduction. It is usually repeated several times in a season. It takes place by the formation of special reproductive cells called spores . The formation of spores in fungi is called sporulation . Each spore develops into a new mycelium. These spores are produced as a result of mitosis in the parent cell and hence they are also called mitospores . The spores vary in colour, shape and size, number, arrangement on hyphae and in the way in which they are borne. They may be hayline, green, yellow, orange, red, brown to black in colour and are minute to large in size. In shape they vary from globose to oval, oblong, needle-shaped to helical. Thus an infinite variety of spores can be observed in fungi and you will find them very fascinating under the microscope. Usually the spores are unicellular. They may be uninucleate or multinucleate. In some fungi like Alternaria and Curvularia they ...
