Lab : The Effects Of Sodium Chloride On Seed Germination

Introduction In this experiment, radish seeds were exposed to several different kinds of solutions (salt, soap, vinegar, fertilizer, distilled water) to test how different environmental pollutants affect seed germination. Because there are several kinds of solutions being tested in this experiment, there is more than one hypothesis. The hypotheses for this experiment are as follows: The use of fertilizer solution increases radish seed germination and growth. The use of salt solution decreases radish seed germination and growth.

The results observed do not correspond with the outcome predicted by the hypothesis. Despite the nature of the subjects of the experiments, no substantial growth was observed. Only one seed of the 36 planted germinated, and it could only survive for a period of a week. The one seed that germinated reach a height of 1.2 cm. Table 1 presents the average growth observed in each quad. Each quad had a total of 12 seeds. No seeds were removed during the course of the experiment.

Plant seeds need water to germinate. Once seeds have started to absorb water, they can begin the process of

The seed did not grow 2. Seed became dark in color Chart. 1. The appearance of plants grew in different area The appearance of a plant can determine in which area is better for a plant’s growth. Plants grow better in an unpolluted area than a polluted area.

Germination is the stage of plant growth through which a seed becomes a seedling plant. First, the seed begins to absorb water and the radicle root emerges from the seed coat and into the water. Then, the primary roots grow, the cotyledons move above ground, the stem begins to grow, and leaves develop. The process is complete when the first leaves open and the cotyledons fall off (The Learning Garden 2001).

This then not only prevents the germination of the seed; however, if the plant were to initially germinate, it would be unable to grow any further, as without enough water, photosynthesis, nutrient transfer, or transpiration would be unable to occur; therefore, the plant would be unable to sustain (Growing Anything,

The second step of the experiment was to soak the seeds in water overnight. This action was made to prepare the seeds for germination and making them more softer and less rigid. The seeds were placed in a bowl and were covered by tin foil. It was set up on the refrigerator to minimize any outside interference that may come to it. After a full night of absorbing the water, the seeds were ready to start the next stage.

2. Question: How does the amount of light a pinto seed gets affect seed germination? Answer: I learned that pinto seeds will germinate faster if they are exposed to less light. The less light that the seed absorbs, the faster it will germinate.

In the article “Seed” William DiMichele discusses the development of seeds. A seed is a part of a plant, that is capable of creating another plant. Inside a plant's ovules, seeds are created. A seed can either be categorized by enclosed or naked, this is based on whether or not they are based on angiosperms or gymnosperms. Inside a seed, the embryo is where the plant grows, the food storage system provides nutrients, and the seed coat protects the internals of the seed. Seeds are created through sexual reproduction, through plant spores acting as reproduction cells. The movement of a seed can be influenced by many outside forces such as wind, water, animals, or people. After seeds

Aerobic respiration is the way toward delivering cellular energy involving oxygen. Cells separate the food in the mitochondria in a long, multistep prepare that produces 32 ATP. The initial phase in is glycolysis, the second is the citric acid cycle and the third is the electron transport system. Germination is one of such procedures that make use of aerobic and in light of the fact that specific variables can influence aerobic respiration, it would likewise influence germination. The chemical reaction for aerobic respiration is:

There are many ways to obtain seeds to grow flowers in the springtime, but not all seeds were created equal. Sunflower seeds, for example, can be bought at a garden store in a packet for $1.5 dollars per 6 gram packet, but they can also be found in bird seed for $3.53 dollars per 10 pounds. This experiment intends to find if the germination of a store bought packet of sunflower seeds matches the germination rate of sunflower seeds obtained from a bag of bird seed. While both seeds will germinate, it is believed that the bird seed will not be as robust in growth as the garden seed, due to the fact that the garden seed is made to be grown, while the bird seed is made for consumption.

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 salt builds up and can contaminate the soil. Knowing the effects of salt on seed germination will allow us to know for sure if the salt is affecting the plants growth or not.

Therefore, I was correct in my hypothesis that dark will have an effect on the germination of radish seeds. Also, I was very close in predicting that the seeds grown in the light will germinate twice as much as the seeds grown in the dark; the control seeds grew a little less than double the size of the experimental seeds. Ultimately, my experiment proved that light is a very important factor in the growth of any plant. However, I’ve learned that seeds grown in the dark will germinate, though slowly, as

Before a seed can germinate it must first shed the seed coat, a protective outer layer that protects the seed from parasites, injury, and unfavorable temperatures. Inside the seed coat is the embryo which contains the root and first leaves of the plant, called cotyledons. After the seed coat has been shed the root emerges first so that it can absorb water and nutrients. After the roots have come out of the embryo the cotyledons will follow. Some seeds need certain conditions to germinate and go

When planting a seed, many factors allow the seed to grow and become a plant. To sprout from the ground, and to survive, seeds need water, air, and a certain temperature. Seeds can get water, oxygen, and sun by being placed at the proper planting depth. Planting depth is the depth at which a seed is placed in the soil. If a seed is exposed to these important needs, it goes through a process called germination. According to the Wise Geek article, “What is Germination?”, “Germination is a process in which a seed or spore awakens from dormancy and starts to sprout.” (“What is Germination?”).
