Germination Essays

Introduction/ Background Information Seed germination is the process by which a plant sprouts from a seed. Biology Discussion displayed the different steps of seed germination, and the first stage of seed germination is imbibition, which is when the seed absorbs water. This causes swelling and thus resulting in the outer coat of the seed to break and then, it will form a root. The next step in seed germination is respiration. This is when the seed takes in water and oxygen and begins to breathe

Seed germination is crucial when looking at a seed's life. It is the beginning of its existence and plays a key role in how the seed will grow from there on out. When looking at seed germination dealing with various salt concentrations, the outcome of the experiment can result in many factors. If salt concentrations affect the rate of seed germination, then a positive control of water would germinate faster than the affected seeds with various diluted salt concentrations. In the end, the effect of

Conclusion: Asian ginseng did affect the germination of the sunflowers seeds. We believe the germination of the sunflower seeds were affected by the nitrogen containing compounds that are found in the roots of Asian ginseng. Question??? Methods 25 sunflower seeds were divided into 3 different petri dishes. 2 of the petri dishes were soaked in water, and the third was soaked in liquid Asian ginseng, for 5 minutes. The seeds of each individual petri dish were placed, wrapped and rolled in 3

Evaluation In this experiment data on the effect of pH levels on seeds germination it is consistent with a single best - fit line. Best- fit line is being used to show the relationship between the pH levels and seeds root length. Since the best- fit of this data is quadratic, I have to linearize my graph to a linear graph. Since my graph is a linear graph this shows that there is a relationship between pH levels and seeds root length. The value of the y- intercept in this experiment represents

My results were fairly reliable, and are very accurate. Beans grow best with fences, poles etc. to climb up. They also prefer full sun. Most of the beans did sprout, but the ones that did probably did not get full sun due to their position. Another factor to explain my results, is the water amount. This was my independent variable, so this was purposely changed. Beans do not like to be over watered, so this explains the 20 mL group not sprouting. My results can be explained by the amount of water

After this 2 week experiment, a lot of data has been collected. As hypothesized in the beginning, the seeds treated with acid rain did not grow as much as those treated with regular water. At the beginning of the each Test, the seeds were all very small and hard. The pea seeds measured 1/4 of an inch, the corn seeds were also 1/4 of an inch, and the bean seedlings were 1/2 of an inch in length. In appendix A and B, the picture shows what the seedlings of both tests look like without any watering

onwards, the hypocotyl of each seedling was measured daily until the second stage of germination (the development of leaves) was reached. Heights were recorded on the data sheet (Table 2), from which a mean was calculated using the equation: A line graph (Figure ) was drawn to show the relationship between the percentage of cotyledon remaining and the height of the hypocotyl on each day until stage 2 of germination was reached. The line graph (Figure ) illustrates that the tallest seedlings were

The data observed and recorded in this lab shows that the concentration of miracle gro’ does affect the growth rate and germination speed of black eyed peas. The data is shown through two graphs and two data tables. The control group in this experiment is the seeds with a 0% concentration of miracle gro’, therefore the seeds with just water. The experimental groups are different concentrations of miracle gro’ including a 10%, 15%, 20%, 25%, and 30% concentration. The variable in this experiment is

The Effects of Different Oxygen Levels on the Germination of Corn and Radish Seeds By LeNaiya Kydd Lab Partners: Michele Morris, Billy Jenkins, Taryn Flink BIOL 3427-005, September 25, 2014, Sarah Mahon This experiment was designed to test the germination of two different kinds of seeds based on the level of oxygen present during this period. The species used in this test were corn and radish seeds. The seeds were split into two groups and placed in two jars, one jar filled to the top with

In this experiment we shall be looking at how pH effects the change in biomass of lettuce seeds after 8 days of germination. It will be interesting to see which seeds radicles begin to grow down and the plumules up and by what amount. To see how the behaviour of the enzymes involved in germination changes when placed in different pH buffer solutions will be fascinating and will help increase my knowledge of the matter. When the pH is low this means that there will be a high concentration of H+ ions

The common bean, Phaseolus vulgaris, is a widely eaten food that is high in digestible fiber (crude fiber). The purpose of this study was to evaluate three different breeding methods (bulk-population, bulk within F2 families, single seed descent) for the genetic potential of the progeny, for the trait of crude fiber. The majority of the sources of variation, besides for the parents and parents by environment interaction, were found to be significant at a P < 0.01 level between the three breeding

Dylin Myers Ms. Rothel Accelerated Biology 22 September 2014 Germination Lab Purpose- The purpose of this experiment is to test the differences of plant growth between areas that have access to light and to those who do not. Research- A seed is, ”a flowering plant 's unit of reproduction, capable of developing into another such plant” (dictionary.com). Germination is, “the stage in which a germ or a living thing starts to sprout, grow and develop” (biology-online.org). A cotyledon is, “the primary

Concluding Plant Growth The hypothesis for this experiment was accepted. The hypothesis was; If the plant seeds were exposed to microwave radiation, then the growing process will increase. Three plants were planted, two of the three seeds, were microwaved for different times to see if microwave radiation helped the plant grow faster. The question that was asked was, does radiation affect the way plants grow? At the end of the experiment, the data collected shows that the plant that was not put in

Seed Dispersal Lab Sam O’Quinn Per. 5 Introduction- Whenever plants grow reproduce, they have to have a method to disperse their seeds. They can do this in one of three ways: through wind, animals, or by water. There are 6 different methods of wind dispersal. There is the glider, parachute, helicopter, spinner, cottony, and the tumbleweed methods. With the glider method the glider swoops through the air and glides the seed. The parachute method works like an umbrella by using tiny hairs at the

We are doing this experiment to study the effects on hormones on the Wisconsin fast plants Standard and the Rosette Dwarf. Hormones are chemical signals that coordinate the different parts of an organism growth and are equally important in most multicellular organisms from humans to plants. What are the effects of hormones on the Rosette-Dwarf Wisconsin fast plants? I hypothesis that the effects of gibberellic acid and abscisic acid would not influence the growth and development of the Rosette-Dwarf

Radiation on different plants could maybe be one of the ways to make plants grow faster. Maybe it could effect a zucchini plant differently than the many other types of plants. Zucchini plants are from the garden family of melons,pumpkins,cucumbers, and gourds.(reader) Electromagnetic radiation could cause a zucchini plant to either sprout faster or slower. This type of radiation comes from a microwave. There are different types of radation such as sunlight,xray,and more. Having different types of

Procedures Day 1-2 Choose the type of seed seed to plant (the seed chosen was mustard greens). Fill each of 6-packs with soil. Place the seed in by making a hole deep enough to cover the seed. Level the amount of soil by using hands. Water the plants with the same amount of water each one.(30mL) Wait until the next day to test the independent variable of amount of water. Day 3 Afterwards, put 30 mL(medium) of water to the 1-6 cups. Then, 7-12 will receive 10mL (too little). Finally, the 13-18 cups

Within the section concerning metabolism and the functions of plant organs, Heinz and Maguire (1973:7, emphasis in original) relate a description given by one of their !kõ informants: Plants breathe, as do animals and humans, but they only do so while they bear leaves. When the leaves turn brown they stop. In the following growth season they begin to breathe again through the leaf buds. Plants drink water with roots and stem. When it rains, the water runs down the branches and stem and it reaches

Introduction For plant reproduction to be effective, the parent plant must disperse seeds where the seed can get enough nutrients to become a mature adult plant and continue the cycle. If the parent plant can not disperse seeds away from the original source of the seed (the plant) then the seed will not stand a chance against the parent plant, in the competition for water and sunlight. Depending on the species of the parent plant, the plant may disperse seeds in one of many ways: wind dispersal,
