groups and due to this do not actually provide the essential nutrients that we need for our everyday lives. These diets do not result in long-term weight loss and are a very unhealthy way of loosing weight. Fad diets are very intriguing because they all promise a quick fix.

as to provide i) the nutrients for the survival of the plant cells‚ tissues and organs under culture and ii) the optimal physical condition of pH‚ osmotic pressure‚ etc. In the culture of plant cells formulating optimum type of medium favorable for in vitro culture was achieved many years ago. The Knop’s (1865) mineral solution was the widely used medium by early investigators. Gautherat (1939) developed callus culture medium from Uspenski and Uspenskaia (1925) nutrient solution.

Plants need water for photosynthesis but they take in water through their roots so they need to transport the water up the stem to the leaves. Water is taken in by the root hairs because there is a higher water potential in the soil than in the root hairs. Then osmosis occurs to move the water from a cell with high concentration of water to a cell with low concentration through the permeable membrane. Once the water has moved down the concentration gradient it reaches a vessel called a xylem. As

treatment that the food receives before it is boiled are also factors that affect the amount of nutrients being leached out. As temperature increases‚ the anchovy particles gain more kinetic energy‚ thus the rate of reaction is faster and hence more nutrients will be leached out. Time will affect the nutrient loss due to different exposure durations having an effect on the amount of nutrients exiting the source and dissolving into the

Eating the right foods can help us avoid certain diseases or recover faster when illness occurs. These and other important functions are fueled by chemical substances in our food called nutrients. Nutrients are classified as carbohydrates‚ proteins‚ fats‚ vitamins‚ minerals‚ and water. When we eat a meal‚ nutrients are released from food through digestion. Digestion begins in the mouth by the action of chewing and the chemical activity of saliva‚ a watery fluid that contains enzymes‚ certain proteins
