Duckweed Are Magnificent Aquatic Plants

all treatments contain the same type of soil, are planted in the same size of pan, are exposed to the same amount of sunlight, and are maintained at the same temperature throughout the course of the experiment. ON THE TEST there will be a number of related questions about this section not just the question shown below.

In this experiment we are testing the effect of fertilizer on the speed of plant growth. We prepared a 4 quad cell, 1 control group and 3 experimental groups. So, we had one with no fertilizer, one with three seeds of fertilizer, one with six seeds of fertilizer, and lastly, one with nine seeds of fertilizer. The plants that we grew were called Wisconsin Fast Plants, members of the crucifer family. These plants are small and easy to grow, but for optimal growth they require continuous fertilizer, water, fluorescent light, and temperature between 18 degrees Celsius and 26 degrees Celsius 24 hours a day. Fertilizers are substances that are put into soils to increase the growth of the plant. There are two different types of fertilizers, synthetic

The growth and survival of a plant depends on the reactions that occur internally called photosynthesis. Photosynthesis is a reaction that captures the sun’s energy and converts it, water, and carbon dioxide into glucose, with a byproduct of oxygen. Glucose is a sugar that provides energy to allow for a plant to grow and live. This experiment is to test how photosynthesis can be sped up with a home solution. The variable being changed in this experiment is the solution that the plant is being given. In this instance, some of the plants will be given Gatorade, rather than water. The question being asked is, How well will a solution found in the home affect plant growth?

The hypothesis behind this experiment is that the Gibberellic acid has a positive growth effect on the plant and causes it grow larger in height.

Native Plant Study- The area that Lake Doonella is located in has great vegetation and variety of native plants which gives the native animals and local residents a beautiful home as well as a lovely sight for tourists. There are numerous different plants in all different shapes and sizes that call this area home. Some plants even have berries growing on them in many different colours for the animals to feed off. During the field walk there were many trees and plants but the most commonly viewable one was the Scribbly gum. ( shown in .. (ref off iBooks)

Duckweed is a small aquatic plant that is able to grow rapidly, making it the ideal specimen for our experiment. It is hypothesized that altering the amount of light received by duckweed will alter its photosynthetic rate. It is predicted that a lower light intensity will lower the rate of growth in duckweed.

However, for each quad, the fertilizer used for the control was added altogether with the fertilizers being studied. Since the only plant that presented growth was in the control quad, it becomes necessary to explore the effects of excess fertilizers, and furthermore, excess nitrogen, would have in the development of the fast plants. Although Nitrogen is one of the elements most living organisms require, some studies have showed high levels of nitrogen can cause toxic stress to some plants, to the point where growth can be inhibited. (Yu et al.

The temperatures tested were 4°C, 30 °C, and 60°C. The optimal growth and prodigiosin production

Today’s lab incorporated the six steps of the scientific method to the growth and development of their own Wisconsin Fast Plant, also referred to as “Brassica rapa” in the scientific community. My group’s experiment included researching the effect of acidity on seed germination. The Wisconsin Fast Plant or Brassica rapa, was originally created by Professor Paul H. Williams at the University of Wisconsin at Madison. The word Brassica can refer to many different plants such as mustard plants, cabbages, rapes, broccoli, brussel sprouts, cauliflower, kale, kohlrabi, turnip, rutabaga, and the Chinese cabbage. The Brassica rapa plants were created to help provide a better understanding and more research on the Brassica plant’s family diseases. Brassica rapa plants are in the Cruciferae family, and are named this way because all of the plants have 4 flowers in the form of a crucifix.

The state of Maine is the number-one maker of seaweed in the United States, and it is already a popular source in many places in the world. In 2006, the state of Maine passed California as the major manufacturer of seaweed in the U.S., and Maine maintained more than 20 companies that produce or gather seaweed in 2015. Maine farmers gathered 17.7 million pounds of seaweed, and that is the highest record for the state and more than four times the 2004. A huge interest in the seaweed products is from Maine small businesses, so seaweed is very popular. Since seaweed is a handcrafted food seaweed farmers do not use the large machines, they often used in farming. However, Maine is not near from being the international seaweed principal. The market

Kelp is a weird plant, you think. It’s slimy and feels weird between your fingers. It’s filmy and almost smooth but not quite. Kelp is interesting though. Despite being slimy, it doesn’t actually slip against itself when wet. Air bubbles connect leaves to the stem of the plant and help it rise towards the surface so it can reach sunlight. The air bubbles and leaves are also almost like notches and hooks that get tangled together in strong currents.

My aquatic invasive species is the water chestnut. Though it is not too common in Indiana waters, it is on the invasive species list, due to the prediction that it will quickly become a threat. It is an aquatic plant native to Eurasia. Currently, it is naturalized in North America and Australia. The states that it is most common in Connecticut, Delaware, Maine, and others on the eastern coast.

What is duckweed? The was the first question that went through my mind when this lab was assigned. This resulted in pre-lab research. The first thing I learned was that duckweed, is a tiny aquatic flowering plant that floats in large quantities on still water, often forming an apparently continuous green layer on the surface. When my group was tasked with choosing our manipulative factor we decided on temperature manipulation. Based on the basic information we all had on duckweed due to our pre-lab questions, my group knew that duckweed is capable of growing in very harsh conditions in regards to pH, temperature, and light. Knowing this came to our advantage when we developed our hypothesis. We hypothesized that while under the different temperature conditions of an incubator, a fridge, and room temperature, the sample of frongs under grown under the incubator would remain healthy throughout the process while

Different species of mangroves gather oxygen in different ways, some use roots that protrude from the ground called peg roots, these peg roots, which are covered in lenticels, can reach up to 30cm in height and allow the plant to exchange gas, as an extension of the roots, which run through the ground, this allows the plant to absorb nutrients from the soil as well, which is a common adaptation in all species of mangroves. Other species are raised from the ground on stilt roots that gather oxygen in the upper reaches of the roots, and then descend into the ground. Slit roots are similar to knee root, except knee root first grow into the ground and then breach the surface to collect oxygen (Marine Education Society of Australiasia , n.d.).
