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

they do it? Well there are multiple ways that this process occurs. All of which differentiate who or what helps the plant spread its seeds. Plants spread their seeds through wind‚ water‚ & animals. A perfect example of how wind disperses seeds of plants is the dandelion. Dandelions have parachute or umbrella like hairs‚ also known as pappus‚ above the one seed in the plant.

Bioassay of Radish Seeds Bioassay is a type of scientific experiment used in the development of new drugs and monitoring pollutants. It estimates the potency of a substance‚ by testing its effect on living matter. In other words‚ it determines how much of the substance is needed to poison an individual‚ without testing it on any humans or animals. From here the TC50 of the substance can be adjusted for dealing with humans and animals over plants. In this lab we attempted to find the potency of

Effect of seed germination Purpose: To see the effect of an acid introduced during seed germination‚ on the length of the plant roots. Also shows how salt can affect the seed germination. Acid can be introduced to seeds during germination if there is acid rain. Knowing the results of acid rain on seed germination will help us understand how to grow pants better‚ and how to have more successful germination. Salt can be introduced into a seed during germination because salt is put on roads and the
