Phytoliths Research Paper

Plant cells have selectively permeable membrane that allows selective substances to penetrate into the cell. Cell membranes are consisting of lipid layer that are made up of phospholipids. (Essays, UK.2013). These phospholipids are amphipathic in nature, which have phospholipids head and tail respectively. Phospholipids heads are hydrophilic and tails

“Plants can absorb water over their entire surfaces, but the greater part of the water supply comes from the soil (Larcher, 1995, p.223).”

One of the best feelings that a person can get while sitting in class is that feeling of “when the light bulb goes on.” That moment happened last Tuesday in class, when Dr. Liu was giving us his overview of Turfgrass. When he explained about how the patterns in the turf are because of the direction that the grass is cut. All those years of playing baseball in middle school and high school came together and the light bulb went off. Learning that special patterns could be done with the help of a roller on the turf was very cool. It would have really awesome to have done a few unique patterns in the outfield in high school. My mind automatly went to the amazing baseball fields that are seen on TV or the Rose Bowl on New Year’s Day every year.

The pH of soil is important for the absorption of nutrients into the plant. Of the 17 needed plant nutrients 14 of them are acquired through the soil. Acidity is needed to break down and dissolve these nutrients. The nutrients are able to dissolve into the soil faster when the acid is acting as a solute. Another way the pH affects the soil is by influencing microorganisms. The bacteria is crucial in the growth and development of the plant, the bacteria’s role is to break down and decompose organic matter in the soil. If the pH of the soil is too high the acid will slow down and eventually stop the microorganisms. Most plants ideal pH is between 6-7, slightly acidic. Many plants are outliers and thrive in pH such as carrots and corn, which can withstand pH as low as 5.5. If the pH of the soil is too high for the desired crop farmers can add material such as limestone, and wood ashes to raise the pH to the desired level. The pH of the soil can also be changed naturally through the leaching of calcium, magnesium and sodium by rainwater. Carbon dioxide from rotting organic matter can also increase the pH of the soil. Acids can also be created organically in the form of sulfuric and nitric

If I had lived during the Holocaust, the hardships would include lack of shelter, starvation, and survival. To start, people struggled to find a safe shelter. The book Milkweed is about a boy who has to change the locations of his shelter to be able to survive. I know that during this time period a lot of people who were jewish were taken to concentration camps were they were forced to work and were treated harshly. Because of this people had to change the location of their shelter to escape getting caught. Additionally, people also had to face the struggles of starvation. Since hitler and his nazis were killing off a lot of people, the people who owned food stores could no longer sell food. This meant that people couldn’t get the same amount

There are a myriad beautiful types of flowers in our lives today that are great for gardeners, but in the United States, one of the easiest to recognize ends up being marigolds. There are more than 50 different species of this type of flower that are all taxonomies by botany into what is known as the Tagetes genus.

When summertime comes, nobody wants to see a garden full of wilted flowering plants that just can’t take the heat. If you want to make sure you still have a thriving garden when the temperatures climb up, check this list of heat- and drought-tolerant plants.

In my research paper, I will attempt to determine how the perception of light in phytochromes plays a role in the development of plants. Specifically, I will look at how phytochromes play a role in the growth and development of Arabidopsis thaliana. The paper will also look at how light perception plays a role in phototropism and the immune systems of a plant. Finally, my paper will explore how changing light conditions impact perception in phytochromes.

Happy Tuesday! Seedlings 2 began their day outside on the playground. We explored so many environmental objects and we moved in response to music and rhythm as we played with musical instruments with Ms. Clara. When we returned to our classroom, we explored floating green objects in our Sensory tub. Later we exercised our gross motor skills as we practice walking with our walker. I do hope you enjoy another fabulous day with Seedlings

Many species of plants host microorganisms living inside the plant forming a mutually beneficial endosymbiosis. Bacteria or fungi that reside within plant tissue (roots, stems, and/or leaves) are referred to as endophytes. These endophyte communities may help to improve a plant’s fitness by promoting growth, protecting against disease, or facilitating nutrient acquisition. More specifically, endophytes within the plant community can help plants respond to stress that develops from biotic or abiotic influences like pests, heat, drought, saline, and soil conditions (Russell et al., 2003) Endophytes can help plants become better able to tolerate stress by allocating resources from one place to another (Rodriguez et al., 2009). Therefore,

There was once a time when dragons and mortals coexisted in unity. This age of tranquility continued on for many years until greed and power planted itself in the hearts of man. Fearing that the mortals' avarice for power would corrupt the world, dragons and the forces of man went to war. The dragons were at a perilous disadvantage and in a desperate effort to end the war, they decided to summon the demon dragon, Lelanthus. This proved to be the dragons' greatest mistake. Like the mortals, Lelanthus had a great want for power. But in distinction to both dragons and humans, Lelanthus had a grave hatred for peace and harmony, and consequently, because of that, he wanted to bring complete destruction to the world.

In 1992, an amendment was made to the Clean Air Act in the US, aimed at reducing the

Phytoliths are a durable floral microfossil formed by silica absorbed by a plant during its life. Although the usefulness of phytoliths in archaeology has been known for nearly a century, the field (independently) has not attained much popularity. Despite the fact that the yields of evidence and information from phytoliths are truly amazing, the field itself is at times more tedious than dendrochronology, causing a delay in the development of the use of phytoliths, as well as the lack of recognition. Phytoliths have been proven to be useful in a number of studies, ranging from paleo-environments, ancient agriculture, ancient technology, even the diet of particular cultures and their livestock. The largest problem with phytoliths tends to

In Arabidopsis, there are five members belonging to the family of ethylene receptors and they all share have large portion of sequence similarity but also each having aspects that allow them to be differentiated from one another. They all share a N-Terminal potrion which is in close association with the membrane, essential for the sensing of ethylene
