of growth in plants over a certain period of time? When tested‚ there is no affect on the growth of plants from a change of an environmental factor‚ such as an exposure to fertilizer. By changing the independent variable (whether or not the plant was planted with fertilizer)‚ you are testing to see how the dependent variable would change (the growth of plants). In order to assure that there is no experimental error‚ a control must be kept to produce the most accurate data on what effect fertilizer

THE EFFECT OF LIGHT INTENSITY DURING PLANT GROWTH ON THE SIZE OF STOMATA IN DICOT LEAVES Christina Durgan Nicole Romero Vanessa Chilunda Biology 101‚ Thursday 1:15pm Claire Burkum 5 December‚ 2013 1. The hypothesis of this study is that the size of the stomata on the dicot leaves exposed to higher light intensity will be smaller compared to the size of the stomata on the dicot leaves exposed to lower light intensity. This is because at higher light intensity there is an increase in environmental

How Does Climate Change Affect Plants? Historical climate change has had a profound effect on current biogeography‚ so we can expect our ongoing and rapid climate change‚ to have as great an effect. Climate change has important implications for nearly every aspect of life on Earth‚ and effects are already being felt. * Temperatureeffects–average‚ minimum or maximum can be important determinants of plant distribution For example the Palmae/Arecaceae are cold intolerant as their single meristem

Enzymes and their importance in plants and animals (25 marks) Enzymes are biological catalysts‚ which accelerate the speed of chemical reactions in the body without being used up or changed in the process. Animals and plants contain enzymes which help break down fats‚ carbohydrates and proteins into smaller molecules the cells can use to get energy and carry out the processes that allow the plant or animal to survive. Without enzymes‚ most physiological processes would not take place. Hundreds of

industrial organizations in Canada are synonymous with the branch plant economy phenomenon. In general‚ "the term branch plant economy refers to a convenient shorthand term to describe a regional economy where a large proportion of the employees are in establishments owned by firms whose head office lies outside the region" (Watts 1). In Canada‚ branch plant economies are subsidiaries of companies based abroad‚ mostly in the U.S. A branch plant economy is a strategic tool used by transnational corporations

organic materials which are used for cellular function (Wikipedia). Plants are an example of this kind of organism. A current scientific topic in regard to photoautotrophs is the topic of non-native invasive plants. When a plant is non-native‚ or exotic‚ it means that it is not originally from the United States. They are often brought to an area by accident‚ possibly for agricultural or horticultural purposes. An invasive plant is one that is established‚ then expand and reproduce on their own

which is used to heat water to create steam. This steam turns turbines which produces electricity. In a standard fossil fuel electricity station the same thing occurs except the burning of the fossil fuel heats the water to create steam. Nuclear power plants can produce more energy using less fuel and thus they are seen as a more environmental friendly source of power. What are the Disadvantages of Nuclear Power? Due to many countries looking to find more environmentally friendly ways of producing

of fertilizers on plant growth | | | Year 11 Biology Year 11 Biology Abstract An investigation was carried out to compare the effect between inorganic and organic fertilizers on plant growth. Tomato seedlings were used‚ which were divided into 3 groups - the inorganic fertilizer group‚ the organic fertilizer group and the control group. Besides using different fertilizers‚ all of the seedlings were planted in the same condition. The result has shown that the plants using organic fertilizer
