Seedling Essays

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

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

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

The seedling represents a seed of doubt and jealousy in Othello’s mind, in the audience’s perspective. In the play, Othello’s susceptibility to jealousy is the main flaw in his personality. The cause of Othello’s demise is due to this very reason. Othello was certain that his wife Desdemona was loyal to him. However, the seed of doubt was planted in his mind by Iago. Iago starts to give hints about how Cassio, Othello’s former lieutenant, was having a secret affair with Desdemona. He starts to hint

Hypothesis: If one-day pinto bean seedlings are soaked in a water solution, 1% NaCl solution, and 3% NaCl solution, the seedlings exposed to higher sodium concentrations will have decreased cellular respiration rates. Treatments: This experiment involved three treatments and a control. The goal of the experiment was to see how different levels of NaCl affect the rates of cellular respiration in day-old pinto bean seedlings. In this experiment the rate of cellular respiration was measured by the amount

percentage of seeds germinated overall, but also actual qualities of the germinated seedlings, such as root and shoot length. Decreased levels of photosynthetic

The purpose of this investigation is to determine the inheritance pattern of the albino trait and whether the albino gene in corn seedlings is dominant or recessive. One group of lab partners in a lab class examine a tray of corn seedlings showing both green and albino plants. The students record their findings and compare their tray of corn seedlings’ results to five other lab groups in the class. The lab students used this information to test all of the possible gene combinations the parents that

The effect of acid rain on seedling germination By Lily and Zeenat 4th May 2017 Question How does acid rain effect seedling germination(bean seeds) Hypothesis The bean seeds being watered with acid rain will begin to dry up, lose colour, start cracking and stop growing Aim To test whether acid rain will have an effect on seedling germination Introduction When sulfur oxides and nitrogen oxides incorporate into rain, snow or mist, the result is acid precipitation. Acid rain is particularly

Identify the variables that the student will need to control in this experiment. The variables that will need to be controlled in this experiment are the amounts of water used per set of three bean seedlings that are growing in large pots containing potting mix. (b) How can she ensure that all the seedlings receive the same amount of sunlight and experience the same air temperature? The student should place both sets in the same area to ensure that both sets get the same amount of sunlight and experience

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 grown from

role from where susceptible host tissue may be attacked. Fusarium avenaceum, F. culmorum, F. oxysporum and F.solani are the more important species involved in diseases of seedlings and cuttings. These species are generally not host specific at the seedling stage and have a wide host range. Fusarium attack can result in seedling death. Fusarium species associated with plants can be pathogens, endophytes or saprophytes. They are widespread and can be a significant threat to production nurseries. They

Both Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco var. menziesii) and red alder (Alnus ruba Bong) use seeds as a method of reproduction. Gymnosperms, such as Douglas-fir, have “naked” seeds (i.e. no fruit), while angiosperms, such as red alder, usually have seeds in fruit (catkins for red alder). Douglas-fir and red alder have seeds that use wings, signifying the use of the wind as a method of seed dispersal. Both trees have seeds than are covered in a seed coat and have nutrient reserves. Gymnosperms

name states, the group that receives the treatment. The treatment groups given in the article are, the seedlings that were moved in the lupine covers. For instance, “lupine cover, depressions in lupine cover, and black plastic mulch in non-lupine cover” (Riege & Sigurgeirsson, 2009). The black plastic mulch, the depression in lupine and the regular lupine were tested and compared to the seedlings without covers to test survival and

Processing of Findings: My hypothesis stated that the microwaved tap water causes the least plant growth. Having conducted the above experiment by watering 2 seedlings with normal tap water and 2 seedlings with microwaved tap water to conclude the original hypothesis. Plant A: From the above table (pg 7 and pg 8) , it is obvious that Plant A grew continually at a steady rate with the largest growth being a 29mm increase in leaf length over the first 5 days and a 38mm increase in leaf width over

The Granny Smith was originally grown in Eastwood, New South Wales in Australia in 1868. Maria Ann Smith led to the initial discovery of the Granny Smith. She found a seedling growing by a creek near her property. She discovered this seedling near the same place she would toss her French crab apples. Smith took advantage of this discovery to propagate this new found variety of apple on her own property. Smith learnt that the granny smith apples were good for cooking with and for general consumption

to implement seeds of fear into the mind of people. The seedlings of fear will grow and perpetuate an image or way of thinking that inhibits the person’s mental state and give control to society. A person’s mind is a powerful instrument molded by factors. Nadine Gordimer’s short story “Once Upon a Time”, shows how the culture of fear can lead to dire preventable consequences. In addition, “Barbie Doll” by Marge Piercy exemplifies how seedlings of fear such as vanity and beauty can destroy a person’s

forward what problems occurred and how she overcame them; she used her knowledge of plants to mirror her life to that of a plants life to compensate for her inadequacies with emotion. She starts off at the base of the plant, using the roots and seedlings as an explanation for her life choice to become a scientist. In her day, females weren’t seen in STEM fields, majority of women

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. The bags treated with water, Controls 1-6, showed the most growth over the bags treated with diluted lemon juice, Trials 1-6. The tables below show the average

The approximate sunlight and ground cover precentage, the number of adults, saplings and seedlings for Red Maple, Tuliptree, Beech and Black Locust were noted. The lab sheet was used as reference for these observations. Conclusions: The hypothesis was supported by the data collected. All the stands that were released from human disturbance after

The advancements made in technology can often be exciting and therefore blinding to effects it causes in the surrounding world. The manufacture of technology and technical devices utilize excessive resources and power and can be hazardous to the environment. Throughout history, the concept of human beings abusing natural elements due to underestimating and overusing technology has been prevalent. Human beings are, by nature, meddlesome in unknown aspects of the environment and the consequences
