This lab tests the process of germination with various pH levels. The pH level of something is its measure of acidity or how basic it is‚ solutions with a pH of less than 7 are said to be acidic‚ and solutions with a pH greater than 7 are said to be basic. The tap water that was used to water our beans had a pH of 6. In this lab‚ we studied the process of germination (the process by which a plant grows from a seed). Certain environmental factors can cause or stop a seed’s germination‚ and these factors

urpose: The purpose of this lab is to determine the impact of light on the germination of seeds Research: A seed is the reproductive unit of a plant that contains a mature ovule with an embryo. The seed is made up of the seed coat hard shell over the seed‚ two cotyledons‚ fleshy membranes that store food‚ an epicotyl‚ which forms the primary shoot‚ the radicle‚ the primary root of the seed‚ and the hypocotyl‚ the stem of the epicotyl. When the seed is triggered by water to sprout‚ a process called

During the lab experiment six different test were conducted. Each test consists of chemicals to be tested using 3 to 10 drops of the additive in order to observe a change. With any experiment you compose a hypothesis; where you make an educated guess. The hypothesis will primarily be‚ which base chemical will produce the greatest change based on the additive. Experiment 6.1 (Starch) when adding the three drops of Iodine to each tube observe the color change. When performing this test the chemical
