Sofia Dominguez 10-O 19/03/14 Effect of pH on germination of seeds: Design Practical Introduction: The term pH stands for Hydrogen Potential it is used to determine the acidity of a substance. The pH scale goes from 0 to 14. The values that are smaller than 7 indicate the range of acidity. Higher pH values are alkaline and a pH of 7 is neutral. Acidity is a function of the concentration of hydrogen ions (H+)‚ or protons. The strength of alkaline solutions is measured by the concentration of hydroxide

Irene C Silfa Dr. Brian MettsBiology 1108 7 February 2014 Effect of Temperature on Seed Germination The reproductive cycle of a plant is a process of constant development. It begins with gamete formation‚ and after several other steps leads into germination. During germination a mature seeds beings the formation of a seedling (Freeman 2011). However‚ before germination the seed is in a state of dormancy‚ therefore the seed must have a favorable environment to disrupt the dormancy (Freeman 2011)

speeds up the rate of germination. But the longer someone presoaks a seed‚ the greater the chance it has to rot. When presoaking seeds‚ one should avoid planting them in dry ground due to the risk of the moisture being taken out of the seeds instead of sticking with it to germinate‚ leaving the seed back to its original state. purpose - There are many factors that affect germination‚ however this lab will determine how moisture‚ specifically presoaking seeds will affect germination. To achieve the purpose

about bean germination: * The time to germination will decrease if you soak the beans overnight * It may take 7-10 days for the beans to ‘sprout’ * Make sure the paper towels remain moist for the duration of your experiment | | | | | | | | | | Procedure 1. Think of 10-20 variables that may affect seed germination‚ recording them in Table 3. 2. From your list of variables in Table 3‚ select three to test. Form a hypothesis for why each affects seed germination. 1

degrees. Abstract Researchers tested the germination of Red Rum Bunching Seeds in different temperatures. Research shows that depending on the seed germination is most likely to occur at a higher temperature rather than a colder one. According to the results the germination rate for seeds at room temperature was 96% compared to seeds in the fridge which germinated at 0% Review of Literature According to Adams the main requirements for seed germination for most seeds are‚ water supply‚ temperature

AbstractDifferent pH level may affect the growth and development of the plants. Certain key words include: pH level‚ germination‚ acidity‚ osmosis and diffusion. This experiment examines the effects of different pH level of vinegar on the growth of bean plants. Materials used in this experiment consist of: water (pH 6)‚ vinegar with the pH level of 3‚ 4 and 5 (each one were made before experiment)‚ beans‚ soil‚ and pots. Eight bean plants were planted‚ two were watered with pH 6 and the other ones

Daniel Wayne Nicol ENF-1 Sue‚ Ranch April‚ 15 2013 Cause of the Green House Effect There are several causes that lead to the environmental condition known as the green house effect which include the burning of fossil fuels‚ deforestation‚ and population growth. The green house effect is rising in temperature over the years because green house gases in the atmosphere trap energy from the sun. The first cause in rise of green house gases is the burning of fossil fuels such as coal‚ oil‚ and

Biology Abstract In this experiment we used dried split peas to extract the DNA and observed the protein isolate. Introduction The purpose of the experiment was to learn what the process was to extract DNA. You also learned the characteristics of DNA and go to observe them. Hypothesis I think the DNA will be really interesting to observe. Procedure Material: * Alcohol * Blender * Water * Drinking glasses * Measuring cup * Paper towels * Freezer
