country’s total forest is damaged by air pollution. This included about one half of the famous Black Forest. Switzerland has recorded damage to 14 % of its forest trees. In this experiment‚ I will find out what consequences acid rain has on the germination and subsequent growth of cress seedlings. I will use cress seedlings‚ which germinate quickly and can grow a few centimetres in a matter of days and sodium metabisulphite‚ which reacts slowly with water to produce sulphur dioxide gas. The seedlings

The Effect of Water on Germination and Plant Growth in Marigolds Question: How does the amount of water given to a plant affect how much it grows? Hypothesis: If I give water to a marigold seed then it will germinate and the plant will grow more than a seed not given water. Independent Variable (IV): the amount of water given a seed/plant Dependent Variable (DV): the amount of plant growth Control Group: The group of plants given water Experimental Group: The group of plants given no water

decomposition chamber contains items that will work as decomposers and as a possible catalyst for plant growth. Examples of possible things to add to the decomposition chamber are leaves and compost. Lastly‚ the terrestrial chamber contains a small plant or seed as well as soil and/or fertilizer or mulch. The purpose of our making the eco-columns is to observe the effect of the manipulated variable on the dependent variable; more specifically‚ what is the effect of fertilizer in the terrestrial chamber on

Several studies show that music possesses properties that affect the growth rate of plants in different ways. These properties may be the wavelength of the music‚ its frequency or even its tempo. According to a study conducted by Margaret E. Collins and John E. K. Foreman‚ entitled The Effect of Sound on the growth rate of plants (2001)‚ plants growth is directly affected by sounds of varying frequencies. They observed that when plants are exposed to pure tones‚ it affects the growth of the plant

within the development of a plant however‚ seed germination is one of the most important phase within the plants life cycle (Baghizadeh‚ Hajmohammadrezaei 2014). Within the experiment conducted by Dkhil and Denden (2010) it was determined that a concentration of 100 mM sodium chloride induced changes within the germination process of okra seeds to a rate of 80.5% where as the seeds prepared with only deionized water yielded a success rate of 100% germination. Based on this result alone one can concur

Two replicates each of 2‚ 4‚ 8‚ 16‚ 32‚ 64‚ and 128 seeds were planted in similar size pots containing an equal mix of potting soil and perlite. All plants were kept in greenhouse conditions exposed to similar light and temperatures settings and were watered at equivalent intervals. At the end of the time period each pot was evaluated for number of seeds that had germinated as well as number

Hypothesis: Germinating seeds will have higher cellular respiration rate than non-germinating seeds. b.) Dependent variable is whether the seeds are germinating or not. c.) Independent variable is the change in CO2 concentration. d.) Control variables: temperature‚ mass of seeds used‚ and volume of chamber. Part 2: Germinating seeds in cold water Hypothesis: Low temperature

experiment was to compare biodiesel to other fuels. The ecotoxicity of biodiesel was estimated‚ along with that of other biofuels through the germination of seeds in the presence of different concentrations of fuels. This resulted in biodiesel having an average of 79.4% germinated seeds in a 10% solution of fuel‚ compared to other fuels whose percentage of germinated seeds decreased with higher concentrations of fuel. In addition‚ biodiesel was also synthesized and its heat of combustion was found through
