What Are The Advantages And Disadvantages Of Aquatic Plants

Competition had a vast effect on  growth, especially on spartina patens.  Both plants flourished, growing the most in freshwater marshes, without the presence of neighbors.  However, with the presence of neighbors, spartina patens was overcome dropping significantly.  While typha angustifolia did drop with neighbors it remained stronger than spartina patens.  In the case of salt marshes, typha angustifolia did not grow at all.  While spartina patens was much more stable with or without neighbors in salt marshes.  This suggests that while typha angustifolia, more dominant in freshwater, unable to grow in salt marshes pushed out spartina patens, who was able to endure salt during growth.  In conclusion typha angustifolia was greatly subdued by abiotic factors, while spartina patens was more limited by

      The general characteristics of the plants in these bodies of water have strong and steady roots, or roots that are bendable, depending on how fast the current of the water is. These traits help the plants mainly so they do not get swept away. Plants that

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.

Plants are found everywhere on earth, up high on the ridge and down low in caves and caverns. The types of plants that live in these places depends on many factors. These factors are separated into two different categories, the biotic factors and the abiotic factors. Some of the biotic factors include, predation, competition, and habitat destruction. Plants with limited competition and large amounts of resources will be in a higher abundance than plants with limited resources and higher competition rates will be confined to areas and either out competed or will be the dominant species. Certain plants adapt to these factors and thrive and others don’t do as well. Some of the abiotic factors include, sunlight, water, temperature, and wind. These

6. Describe several adaptations that enable plants to reduce water loss from their leaves. Include both structural and physiological adaptations.

Underwater grasses, or Elodea, was observed as well. This wide variety of life is a good indicator of the water’s health.

Although sewage systems are able to provide a great deal of sanitation to water before it is released back into a source, the risk of raw sewage overflowing into water sources poses several issues. Not only can raw sewage contain harmful bacteria such as E. coli, it can also negatively affect aquatic life. Human waste typically contains high levels of nitrogen, phosphorous, and other nutrients that are useful for people but can cause many issues in an aquatic environment (Burkholder et. al., 2011). Much of these elements are removed during wastewater treatment, but if they are sent directly to a water source due to flooding, they can cause algae blooms and harm

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.

Floras and microbes are additional main biotic mechanisms of many oceanic ecosystems. Microbes act as decomposers for oceanic ecosystems, and they break defunct living matter and transforms it into vitality that is used by other existing organisms in the oceanic ecosystem. Detrivores, which are a type of animal, also eat deceased or putrefying plants and animal matter. Algae, which are autotrophs, appear as the head herbal vivacity and primary producers in oceanic ecosystems. The sunlight transforms the light into energy for nourishment for marine plants. Heat and light are focal abiotic factors discovered in essentially all oceanic ecosystems, consequently oceanic ecosystems has some broaden abiotic mechanisms, comprising viscosity and many more. The power that the bulk of an organism is called buoyancy. The durability of the drive of seawater is called viscosity. These abiotic factors source to the drive of all organisms in oceanic systems. Sunlight pierces the sea exterior only about 65 feet. As there is more salt in the Great Barrier Reef than in other oceanic ecosystems the marine holds less oxygen than the

Hypothesis: The duckweed will show a small growth increase with very low levels of salinity and then will show a decline in growth rate as the levels of salinity increase.

Characteristics of hydrophytes include: a thin cuticle (primarily prevent water loss), thus most hydrophytes have no need for cuticles; stomata that are open most of time because water is abundant and therefore there is no need for it to be retained in the plant. This means that guard cells on the stomata are generally inactive. An increased number of stomata that can be on either side of leaves; a less rigid structure (water pressure supports them); flat leaves on surface plants for floatation; air sacs for floatation; smaller roots (water can diffuse directly into leaves); feathery roots (no need to support the plant); specialized roots able to take in oxygen.

Each section we added ( ml) of liquids. The null hypothesis that the growth of plants will be at its optimal value with tap water having a neutral Ph. The alternative hypothesis that there will be no change on the growth of plants in different liquids. Introduction:

Have you ever wondered what would happen if plants grew in acidic water? What about bottled mineral water? Water with fertilizer? Well, now you can know! In my experiment, I will be testing which type of water will help the plant grow better. In this case, I will be using duckweed to test the water. Duckweed is a very small, green plant that floats on the water’s surface. My hypothesis is that the duckweed will grow best in fresh water because duckweed is usually found growing abundantly in freshwater ponds or lakes.

In experiment two, the data revealed clear evidence which amount of scoops had the most effect on photosynthesis using nutrients. This experiment ran smoothly. The results were clear and agreed with the predicted results. In conclusion, higher level of nutrients that is distributed into the water plant are proven to be more beneficial to the water plant.

The plants that grow in saline soils have diverse ionic compositions and a range in concentrations of dissolved salts (Volkmar et al., 1998). These concentrations fluctuate because of changes in water source, drainage, evapo-transpiration, and solute availability (Volkmar et al., 1998). Due to these varying conditions, plant growth depends on a supply of inorganic nutrients, and this level of nutrients varies in time and space (Maathius and Amtmann, 1999). Either extreme condition concerning nutrients results in deficiency or toxicity in plants, and this is demonstrated by salt tolerance (Maathius and Amtmann, 1999). These conditions vary according to the plant species and growth conditions. Little is known about the genetic basis for diversity of salt tolerance in plants, and this could be partly explained through the definitions given for salinity.
