An introduction for the germination experiment Lab Report

An introduction for the germination experiment - Lab Report Example Seed germination process is comprised of several steps. First, the seed absorbs water from the surrounding environment through osmosis. Water absorbed activates enzymes, increases the rate of respiration and leads to duplication of plant cells. Secondly, the chemical energy stored as starch is converted to sugar and serves the embryo as food during the process of germination. The embryo is nourished and enlarged resulting in seed coat burst. Lastly, a root tip known as the radicle emerges from the seed and grows downwards to anchor the seed. The radicle enables the embryo to absorb water and minerals from the soil (Jirage 1). A study on the effects of treatment on seed germination will be carried out as a laboratory experiment. The experiment will involve a non-dominant maize seed and a treatment acid. The experiment will comprise three setups. The first set-up will involve low level of the acid and the second will contain high levels of the acid. The third set-up will be a control- experiment that will not involve any treatment. Pre-treating with an appropriate concentration of Gibberellic acid (hormone G A3) plays an import role in the induction of tolerance to salinity. Additionally, it helps the seed overcome the environmental stress, such as osmotic effects, nutritional imbalance and ionic toxicity. This can be achieved through strong root and shoot length that gives a response to salt stress (Jamil
