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 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

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

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

Seed Dispersal Project by Ben Fesenmyer   Introduction   Plants make seeds to ensure the continuation of the species. The seeds that the plants make need to travel to get nutrients sunlight and water seed dispersal is how plants spread the seeds. There are 3 ways to spread seed by water by animals and by wind, in my project we are spreading seeds by wind. Wind dispersal is the most common method to spread seeds, the three main types of devices that carry seeds they are helicopter, glider and parachute

In Which Solution of Fertilizer Will Seeds Germinate the Fastest? Background Fertilizer is a substance applied to a plant, or surrounding soil, to provide extra nutrients for the plant. Fertilizer is used by many farmers, gardeners, etc. to assist plants in growing faster and having better quality crops. But at what point does the fertilizer essentially “cap out”, meaning, at what point does adding more fertilizer not give the plant(s) any additional assistance? The plant being tested in this 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

Life Cycle of a Seed Plant Annotated Bibliography Dante, R., Larkins, B., & Sabelli, P. (2014). Cell cycle control and seed development. Frontiers in Plant Science, 5. Dante et al. mention that seed development is complex and needs a coordination of the processes including metabolic, genetic, environmental cues and physiological pathways. According to the article, different cell cycle types often occur in sequential and in overlapping manner when the endosperm and embryo are developing. Dante et

Cotton seeds are usually planted by a girl/woman, along with a mule, plough, and a harrow. This occurs during the months of March and April. To plant the cotton seeds, a plough is used to produce beds with the help of oxen and mules. After this, a plough is drawn by a mule and creates a drill where a girl will drop seeds. Then, a mule and harrow covers up the seed. “Scraping cotton” is when a plough travels near to the cotton and throwing the furrow from it. Then, slaves would come with hoes to cut

Alaina Couch Effect of Salinity on Seed Germination and Plant Growth During this experiment, we tested the effects of soil salinity on the germination and growth of Wisconsin Fast Plants. Wisconsin Fast Plants, also called Brassica rapa, are closely related to brussel’s sprouts, kale, cauliflower and other vegetables of the Brassica genus. These plants were bred by Dr. Paul Williams and under favorable conditions, they have the ability to complete their entire life-cycle in just 28 short days (Williams

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

affected the germination of seeds. My group’s original hypothesis was that the seeds with the highest concentration of “Miracle Gro” would grow the most compared to the other seeds. However, after 8 days, the results were the exact opposite; the seeds that got 0% of “Miracle Gro” turned out to be the healthiest and tallest. By the third day, all five seeds, for the water solution, where sprouting. On the other hand, the solution with 4% “Miracle Gro” only had 3 seeds starting to sprout. In addition

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 they were given and the viability of the seeds. Not all seeds germinate no matter what you do, my average viability rate was about 50 - 60 percent. I think that the reason for 50 % of my seeds sprouting is due to the water that they were given.

maples, but only develops one seed per pair of Samara. Towards the beginning of the trees lifespan the bark is smooth and gray, but as the tree ages the bark shags and thin strips begin to peel on the ends. With its leaf veins, embryo with two cotyledons and broad leaves the Silver Maple is well considered a dicot.

that is infertile or acidic. When selecting a site, do pH tests on the soil. The pH should be above 6.5. If your soil is too acidic and you cannot afford to fertilize your alfalfa a lot, then do not plant alfalfa. Make sure that you prepare a good seed bag. If a seedbag is not smooth and free of large clods, then it is not good enough. A drill must be used to plant the alfalfa. Do not use a till. Once the alfalfa is planted make sure you check on it at least weekly. There are many insects and animals

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 different

a microwave. There are different types of radation such as sunlight,xray,and more. Having different types of seeds grown by the class then the class can tell if radation really does help plants. The hypothesis for this experiment of how will radiation affect seed growth is “ If plant seeds are exposed to microwave radiation then the growing process will increase.” My seeds(zucchini seeds)will be placed in three cells and cell number one will not be microwaved at all. Although cell number two and

Senegalia berlandieri (Acacia berlandieri) commonly known as Guajillo, is a legume small tree or shrub growing in northern Mexico and southern Texas. It belongs to the Leguminosae or Fabaceae family. It has seeds born in pods, compound leaves with numerous leaflets, and the roots are associated to bacteria that symbiotically fix nitrogen. This plant produce foliage and that are usually abundant in nitrogen compounds with a good indispensable amino acid composition. In addition. The plant provides

Michael Pollan’s book tells the story between the relationship of Man vs Nature, and the connection it has with life on Earth. He mentions his objective for his book: to view plants in an intimate relationship with humans by looking at ourselves differently. The book makes an adventure through history to forms of life now, and examines plants through multiple points of views. The Botany of Desire demonstrates a unique comparison of the terms “Botany” and “Desire” through his four chapters:apple,tulip
