Energy Flow
Energy Flow - All living beings require a constant supply of energy for the various functions they perform. The energy is obtained from the sun. This energy is introduced into the biosphere by green plants by a process known as photosynthesis. Plants are able to trap this light energy and..
Mobilisation of Reserves during Seed Germination
Mobilisation of Reserves during Seed Germination - During germination the cells of the embryo resume metabolic activity. The stored fats, proteins and starch are digested. The insoluble food is made soluble and complex food is made simple. Assimilation of this food by the growin..
Energy Flow
Energy is the capacity to do work. Solar energy is transformed into chemical energy by the process of photosynthesis, and is stored in plant tissue and then transformed into mechanical and heat forms during metabolic activities. The energy, in the biological world, flows from th..

Water can act both as an oxidizing as well as a reducing agent. With active (more electropositive) elements, water acts as an oxidizing agent and in turn gets reduced to give H 2 gas. The reduction potential for the reduction of water at [OH - ] = l0 - 7 mol/L is - 0.41 V, viz., ..

The radiant energy from the sun is the source of both light and heat energy to photosynthesis. Light energy is harvested by the pigments in order to carry out the breaking down of water molecule into hydrogen and oxygen. This is an energy-intensive process. Sunlight can be split into seve..

The compensation point is the point at which the rate of uptake of CO 2 by a plant is equal to the rate of output of CO 2 . It indicates the point at which the rate of photosynthesis and rate of respiration are exactly equal. A limiting factor is the factor, in a chemical reaction i..
Plant Water Relations Introduction
. Without the constant supply of water the plant cannot carry on any of its physiological activities such as photosynthesis, respiration and growth. Obviously an understanding of the manner in which plants get water is important. In this chapter we shall study the absorption, tr..
Polygraphy
Polygraph is a simple instrument that records qualitative changes in physiological parameters. These parameters include vital changes like cardiac variables (ECG), heart pulse rate (HR), relative blood pressure (BP), rate of breathing and so on. Popularly called the lie detector. A ..
Presence of Carbon Dioxide in Air
Another important constituent of air is carbon dioxide. As stated before, plants use it to synthesize carbohydrates, a basic food for all of us. It is also one of the green house gases that help to retain the warmth of the suns rays on earth, making weather conducive for life. You can perform the ..

Tutors are AMAZING, and They helped me understand every single part of the problem and because of the way they explained everything, i had no questions to ask. It was a learning experience to remember. :)
My daughter is in 9th grade and I was having a hard time helping her. I am finding TutorVista very helpful. I don't want my daughter to think she knows more than her Mom :-) Thank you all - Megan
Good teaching skills, an amazing tutoring, would recommend it to everyone - Maadai
Extremely helpful, would love to have more session. Tutor gave me a clear understanding of what I needed help with the most. Great session.
