money. A prairie is a large open area of grassland. There are a lot of prairies in the Mississippi River valley. Prairies are also treeless environments that are dominated by herbaceous plants. The environments also include varying levels of soil fertility. They also provide a safe habitat for a very diverse plant and animal community. Andropogon Gerardii (big bluestem) is the dominant grass species found in the tallgrass prairie ecosystem. It can reach up to 8 feet (2.4 meters) in height and…

This also includes Daintree National Park, Daintree river and some privately owned land, with a community residents with 5 people living there.The tropical rainforest ecosystem of the Daintree Rainforest is Almost the most complex on earth. Its plant diversity and structural complexity is unrivaled on the Australian continent and represents the origins of its more familiar ‘Australian’ flora. Millions of years ago the Australia was warm and humid also rainfall was plentiful. During that time…

production. Seed treatments protect soybean seed and young soybean plants from diseases and other threats to plant health and yield. Variety selection. No soybean variety is completely resistant to powdery mildew, but some varieties are much more susceptible than others. It’s difficult for companies to evaluate and breed for resistance because, in most years, powdery mildew pressure is low or nonexistent in soybean fields. It’s always wise to plant-disease free seed. Good weed control from…

believe the Root Rot Pythium has a much greater impact on a Corn plant. There is a much greater impact because the time of infection is at a much earlier time when the plant is just a seedling and has a slim chance of fighting off the necrotrophic disease. When Pythium attacks the seeding through the root system the bacterial pathogen leaves behind an enzyme that completely breaks down and kills cell walls. This eventually kills the entire plant in the seedling stage. So, in both Goss’s wilt and…

History All plants need water, but plants may prefer one type of water over another. There are two main types of water, tap water and rainwater, and each type of water has its pros and cons. Different plants need different amounts of water. Along with that, some plants also need water more frequently. This writing is going to explain about how plants prefer one type of water over another. There are many chemicals added to tap water. The uses of these chemicals is to disintegrate any dirt in the…

grapes, such as parasitic fungi and environmental bacteria (Barata et al. 2012). Similar to other plants grapes also have to deal with the two major microbial, fungi and bacteria. These microorganisms play a major role in grape's ecology. Fungi and bacteria can help grape plants however, it can be pathogenic and can cause diseases. Grapes can be attacked…

Introduction: Once a plant begins growth, it depends on multiple abiotic factors to continue growing: light, carbon dioxide and water. These three factors affect the growth rate of a plant, causing it to grow quicker or slower. Furthermore, altering these factors may stunt plants growth or improve it. For example, plants require an adequate amount of water to survive. Water hydrates the plant and also breaks down the minerals in the soil. As the plant absorbs the water, nutrients are transported…

went to the green houses for the first time and were assigned a species of plant that we were to nurture for the following weeks. These plants ranged from I was assigned the Giant Creamy Yellow Zinnia. Throughout this process Professor Stewart taught us about soil alternatives and the benefits of growing plants in a green house versus growing plants outside. I thought it interesting when comparing the background of the plant to what I observed in actuality. The Giant Zinnia or Zinnia elegans…

Plants and animals have made changes in their habitats as they have transitioned from water environments to land environments. This alteration requires the organisms to adapt to their new environments in order to survive and reproduce. These evolutionary transitions eventually led up to alterations in means of respiration, ways to prevent water loss, water dependent reproduction, and structural transformations. Amphibians evolved into reptiles and eventually into birds and mammals, being able to…

specifically in drought. In situations of long periods of drought it has been researched that oak trees lose their ability to effectively perform photosynthesis. Photosynthesis is the process in which sunlight is converted in to chemical energy. Plants make their own food by using energy from the sun to make glucose. There is a practical reasoning behind understanding if adaptations in leaf traits, water transport, osmotic potentials, root depth, and tissue elasticity allow for better survival…
