Germination Test Lab Report
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 germination begins. Germination refers to the sprouting of a fungal seed or, more commonly, an angiosperm or gymnosperm plant. The process ends when a shoot emerges from the seed. This lab tests whether the germination of a radish seed is affected by the amount of light it receives. One control group is set in a room that will have normal light conditions, while the other experimental group is placed in a dark room without light. Ten seeds will be placed in each group, with a three day period allowed for the seeds to germinate.
Materials and Procedures:
Scissors
20 radish seeds

Therefore, light was not required for germination. This was because the cotyledon, a fleshy membrane in a dicot seed, provided food for the seed while it was germinating, so that it is not required to create energy through photosynthesis. The plants in the dark had a color change because they were unable to undergo photosynthesis. Additionally, because there was no light to direct the plants in the dark, they did not all grow in a uniform direction as the plants in the light did. Because both plants had an equal germination rate and both were exposed to water, water starts the germination process. It ends when the seed sprouts a shoot. In order to germinate, light is not required because of the cotyledons food storage, but water remains necessary to ensure the survival of the
