Word Count: 1982Aim: The aim of this lab is to examine how the affect of high concentrations of zinc, copper, and phosphorus have on water hyacinth. This lab also intends to stimulate this as a non-point source form of water pollution in this highly invasive and sustainable plant.
Research Question And Justification
How does the exposure of high volumes of phosphorus, zinc, and copper affect the sustainability of the plant? If it does survive the exposure to the stimulation of non-point

Water hyacinth are one of the most invasive species, especially in Florida. The originated in the Amazon Basin, and after this first introduction the spread of this aquatic plant soon began to dominate the majority of freshwater environments. The can easily cover a large portion of a pond, as the multiply a lot faster than most floating aquatic plants. Water hyacinths scientific name is eichhornia crassipes, and are predominantly noted as being a floating aquatic plant that has no attachment to the floor of the pond or lake. Water hyacinths are the only aquatic plant that has this quality. They are characterized by their full foliage and prominent green leaves. Their bloom is pale lavender and depending on where these plants are on a global scale. Their roots start off very bulbous as their purpose is to hold in as much water as possible and provide enough air that the hyacinth stay buoyant. The roots then build up and continue to fan out into very dense, waxy leaf. Water hyacinths are strictly freshwater plants, as placed in an environment that has high salinity, or even

Water hyacinths can be used as buffering agents, and with the presence of other plants int he experiment can be a sure sign of how successful or how unsuccessful these plants can be used as buffers.
Procedure
Put on gloves, and start in an area that will have a balance of sunlight and shade for water hyacinths. Make note how green and how well the foliage is forming and if there are any signs of the plant dying or being malnourished.
Measure out freshwater, equating enough for all three plants, especially when the plant is submerged in the water. Measure how much each plant weighs, and how wide and tall the plant is.
Gently submerge the plants into individual containers, as we are testing the effectiveness of each metal. It is okay if these plants are completely submerged in water, as they will balance out. Don’t force the plants to squeeze into these containers, if need be, find larger containers. The amount of water should be around 6 oz, place the plant in and then top off with about 5.2 ounces of freshwater so the plant is
These not only affect the plant in their specific ways, they also have different effects when they are present in certain ratios with the other chemicals. Plant hormones maintain a delicate balance, and this experiment serves to observe that balance (Campbell and Reese, 2008).
Have you ever wondered how are plants are different from each other or how are plants seeing a different outcome and affect? Well, sometimes all different kinds of plants has something that will be added more and even added less towards the structure. For instance, you should look at like by the type of water and how it could benefit it or not,even the type of seed and how it could benefit or not.In addition, Tap water has bad stories behind it, saying like the toxins in Tap water can accumulate in your body for years, so if tap water is added to a plant it could probably make the plant die in a few hours or even the plants wouldn’t have much of a growth. And others saying that Spring water is clean the Tap water.
5. What is the advantage to a plant of closed stomata when water is in short supply? What are the disadvantages?
Hypothesis correct?: Yes and no. The tap water did soak up the color best, however the plants in soft water and the reverse osmosis
5. Roots in and out of water. Leaves might need to excrete salt or waste. Won’t rot or mold.
The Eurasian Watermilfoil or Myriophyllum spicatum is native to Europe, Asia, and North Africa1. It came to the U.S, New England circa 1880-1940 and most likely came over seas by the aquarium trade or when people were traveling by ship1. It was first found in Maine in 2003 in a small body of water3. This species can be found pretty much all over the U.S but specifically it is found in wet marshy areas2. The Eurasian Watermilfoil is an aquatic plant and is devastating to the ecosystem. This plant spreads by creating fruits with nuts that can get eaten by animals and by having the nuts just fall from the plant. It also spreads by dropping parts of the stem that can regrow into new plants2. The way the plant populates makes it very thick when
We all know that every single plants need water to survive and to not dry out , even bouquets of cut flowers and plants living in deserts need water no matter where they are located. But have you even thought about how A plant looks after it has absorbed dye water ? Put the carnations in dyed water to figure out where the water goes through a plant. Where do you think the dyed water will travel while the plant has absorbed ?, What will this show about how water moves throughout a cut flowers or plant?
Low pH (4.6), the optimum level between 4.8 and 7.8 (CaCl2). Low because of the white clover
Albright et al. (2004) studied about the abundance and distribution of water hyacinth in Lake Victoria and the Kagera river basin during 1989-2001. Water hyacinth (Eichhornia crassipes (Mart.) Solms) is an invasive aquatic macrophyte associated with major negative economic and ecological impacts to the Lake Victoria region since the plant’s establishment in the 1980s. To assist the management and mitigation of the above problem, Clean Lakes, Inc. and the U.S. Geological Survey’s EROS Data Center have acquired and analyzed remotely sensed imagery, conducted field work, and compiled reports to document the abundance and distribution of this plant, from its establishment to then. Remotely sensed imagery was processed and analysed to identify areas
Pick up the watering can that you had just filled with water and then pour the water onto the soil of the already potted plant. Pour the water onto the plant for about 6 seconds. You do this so that the soil and roots will easily come out of the pot. (physical, Cognitive)
Over the recent years, freshwaters have decreased dramatically due to water pollution. Therefore, 3% of water is freshwater and 97% is saltwater. As the result of this water pollution can have a meaningful consequence not only to animals and humans but as well as to plants. In addition, it causes an eruption of a current plant growth by harming the earth’s aquatic environment by altering the plant’s surrounding pH level. Acid rain is formed because of the atmospheric sulfur dioxide and nitrogen dioxide which is produced by human-made sources. In fact, with most of the environment freshwater from lakes and rivers, one of the most common aquatic plants are American waterweed the elodea plant. The behavioral function of this plant is to float
Body Paragraph # 2 - Objective: The purpose of this experiment is to compare the effect of plant growth and biodiversity. I want to know the effect that water has on growth when it is contaminated, purified, or at its original state. With water being the major prerequisites to a healthy life I want to know what would happen to me or other species if I were to drink contaminated water or continue to drink the bottled purified water instead of drinking tap water.
To study the effects of hypotonic, hypertonic and isotonic solutions on plant and animal cells.
In this technique, the plants are cultivated in a narrow horizontal pipes wherein a thin layer of nutrient rich solution is flows and circulates through it continuously (TECA, 2015). This system is only suitable for small-sized plants because large plants that have big roots will clog the pipes. The plants are placed in a net pot within the holes of the pipe. In this technique, a mechanical solid separator and biofilter needs to be added. a biofilter is necessary because that is where the nitrification process will
Different environments and soils have their particular characteristics, which makes it nearly impossible to follow a pattern. Water is essential for moving the necessary nutrients through the roots of the plant to where they are required for forming the flowers.
