Types Of Light And Nutrients - 1881 Words

Question 1 Light and nutrients are two key factors that are crucial for plant growth and development. The types of light required by plants are wavelengths of light that are invisible to the human eye. This light is needed to induce certain responses critical to plant development and survival. For example, the change in levels of phytochrome red light and phytochrome far red light allow plants to begin flowering, germinate, break dormancy, or senescence. Each plant species has a different photoperiod that dictates when each of these types of responses will occur depending upon the members of hours of light the plants receive. Some plants are short-day plant, meaning that they require few hours of daylight and a greater number of hours of†¦show more content†¦Depending on the plant species requirement of certain nutrients may vary. However, the main nutrients that are needed for all plants are carbon, hydrogen, and oxygen. These nutrients are actually procured from the air instead of th e soil. Nitrogen, phosphorous, potassium, magnesium, and sulfur are nutrients that plants get from the soil and require them in large amounts, especially nitrogen. Other nutrients needed on small amounts include iron, boron, copper, manganese, molybdenum, zinc, cobalt, chlorine, and nickel. While the general understanding might be to always ensure that plants have access to adequate nutrients by supplying fertilizer, some plants like soybeans and alfalfa have nodules that work with bacteria to fix their own nitrogen. However, if enough nitrogen is always supplied to the plants they may not use this ability much as much. Therefore, allowing plants the opportunity to use their own abilities to procure nutrients can be a method of improving the efficacy of plants. Keeping these ideas in mind can also greatly enhance the plants ability to get closer to their full genetic potential.

Studies on plant responses to multiple stresses often deal only with stresses linked to limitations in several resources such as nutrients, inorganic carbon or water availability, light quality or quantity and focus on the optimization of resource acquisition and allocation. In fixed water, when exposed to increasing nutrient stress, plants tend to have a reduced total dry mass and leaf number (based on Zhang, 1996; Crossley et al., 2002), increased allocation to root and stemRead MoreUnder What Climate Conditions Do You Find Tropical Savanna Ecosystems?1549 Words   |  7 Pages because light penetrates all the way through the water to the bottom part of this zone.

Behind the Sugarcoated Eye It’s dark, quiet, and you’re all by yourself. You whine and yell for help but nobody seems to hear you. The people you thought were your family abandoned you, left you all alone in a small confined cage. There is no place to use the bathroom, other than where you stand. The awful stench of your feces grows worse and worse each second. The only food they left you with, you ate in the first day. Now the only thing keeping you alive is your desperation to eat and drink your own waste and the will to survive.

Yet an animal such as a Lion in the zoo are raised outside of their law protected boundaries. A Lion from the zoo is used to instructions as opposed to a Lion from the jungle that is free to roam and explore as he pleases. The current animals rights provided by our government do not apply to the animals in the zoo. If an animal in the zoo disobeys an order given they are sometimes beaten. For years we’ve heard stories of animals turning on trainers attacking them. I do not wish death upon anyone, but these stories come as no surprise to me. Wild animals do not belong in a zoo within a created environment. Animals have rights and belong in the wild to live and die as they have since the beginning of time. No pen or even Safari’s that are drive-through can measure up to the freedom of the wild.
