Cyanobacteria Essays

green algae example is volvox. How are green algae different from cyanobacteria? ` Cyanobacteria are photosynthetic bacteria while green algae are photosynthetic eukaryotes. Cyanobacteria do not have a nucleus or mitochondria while green algae do. They reproduce asexually while green algae reproduce both asexually and sexually. Green algae are symbiotic with fungi and are a major food source to the marine environment. Cyanobacteria are harmful to some marine species. They both go through photosynthesis

Cyanobacteria are among the oldest life-forms to have been discovered. They would occupy highly mineralized warm springs. Cyanobacteria contain chlorophyll; which is a green pigment responsible for photosynthesis. “The photosynthesis carried out by the stromatolites was on such a large scale that they consumed most of the carbon dioxide in the atmosphere and released enough oxygen to make permanent changes.” (Arizona, 2016) Bacteria are extremely resilient and some are capable of living in the most

Drinking Water Is the Way to Go Specific Purpose: To show to my audience the importance of water to our body and to encourage them to drink water more often. Central Idea: Many people may take drinking water for granted, but keeping hydrated can have a huge impact on overall health. Despite how crucial it is that people drink enough water, a significant amount of people may be failing to drink recommended levels of fluids each day. I. The Attention Step Water is virtually everywhere, from soil moisture

The purpose of this experiment was to see what the effects of light and dark would have on photosynthesis and cellular respiration. With the knowledge gained in class about how both the reactions took place. It was predicted that the absence of light would slow down photosynthesis causing less O2 to be released in the water. It was also predicted that the beaker with the fish in the water would yield a higher concentration of CO2 in the water. These predictions were made based on the fact that plants

The focus of this experiment was to demonstrate how the contrasting quantities of nutrients added to a cabomba plant affects photosynthesis. The research question that conducted the experiment was, ‘How does different amounts of nutrients affect the photosynthesis of a cabomba plant?’. It was hypothesized that if different amount of nutrients affect the photosynthesis of a cabomba plant, then the water with 6g of nutrients will cause the greatest amount of photosynthesis. The procedure for this

Swimming at Norway Lake Every summer, my family and I go camping. There is a special place that we always go to, it is Norway Lake Campground. There has never been any incidents where I would say that it is unsafe or boring, until this on summer day. It was the summer of 2008, it was beautiful out. The birds were chirping, children were laughing, and you could feel the sun tingle on your skin. This was soon ruined by a horrid moment on the beach. It was a tradition that everytime we camped at

Nancy started explaining about the process, “Well the long process is called photosynthesis. Lets talk about the interior of a plant cell first. Unlike animal cells, plant cells have chloroplasts. This absorbs light from sunlight and produces food for the plants,” said Nancy. Nancy grabbed a small branch with her beak and drew on the dirt to describe the chloroplast. “the interior of a chloroplast is a layered structure, containing the functions shown in this diagram.” showed Nancy. “Wow! so many

Cyanobacteria or cyanophyta is commonly known as blue-green algae which is a type of bacteria. The colour pigment they have is from phycocyanin along with chlorophyll. Chlorophyll is in all green plants, algae and also cyanobacteria which helps them absorb light to create energy to be able to perform photosynthesis. Cyanobacteria grows at the ocean shore or pools and ponds at their edges although they can be found in soil, water and salt water. Cyanobacteria live in sheets like films, but thin enough

Background Information The purpose of this experiment is to monitor how different plant species affect photosynthesis. To measure how the different plants affected photosynthesis, we measured the levels of carbon dioxide. The question that we researched was: How will different types of plants affect photosynthesis and rate of respiration? We believe that if cedar is placed in the chamber and undergoes photosynthesis then the carbon dioxide levels will go decrease the most because the most photosynthesis

In the BIO 14 Lab, we attempted to design an experiment that would tell us something about the on the phenotypic plasticity of the stimulus-response Mimosa pudica. The specific question being asked in our experiment is: What is the effect of extreme light conditions in Mimosa plants grown in both short-day and long-day conditions on the time it takes for the plants to reopen their leaves after a heavy (1g) or a light stimulus (0.3g)? Does this behavior change when under conditions of normal long-days

pigments involved in the process of photosynthesis, converting light energy into sugar. Cyanobacteria, known before as blue-green algae, perform photosynthesis. Bacteria can use multiple dyes. Although cyanobacteria mainly use chlorophyll (green) and phycocyanin (blue), it also contains carotene (orange) and xanthophylls (yellow). We deducted an experiment to investigate the photosynthetic pigments of cyanobacteria using the electrophoresis and thin layer chromatography (TLC) methods to divide and examine

determine the effects that low pH levels have on the growth of cyanobacteria and algal species, by testing various concentrations of sulphuric acid (H2SO4) in different samples of cyanobacteria and algae of equal volume. My hypothesis is that the lower the pH level of the water, the less the cyanobacteria and algae species will grow. Thus the higher quantities of sulphuric acid in the water will result in the lowest growth rate of the cyanobacteria and algae species. Various chemicals have been released

is a strong focus on the addition of Phosphorous and added toxins because both are key elements in growth in lakes. The Virtual lake includes these five simulated species; green algae, cyanobacteria, bosmina, daphnia, and trout. There are two types of phytoplankton in the lake model, green algae and cyanobacteria. Green algae are a very diverse group that are photosynthetic, aquatic, plant like organisms that have a very simple reproductive structure. Green algae growth is a healthy and natural part

The Theory of Evolutions was proposed by Charles Darwin and he surmised, that all living beings from multicellular form to single celled beings were descendant from a single ancient source that have adapted and evolved into their current form (Open University, 2016). This theory gives way too many of our current inspirations in science, we still desire to achieve linkage from one specie to another to prove the source of that particular species. In my opinion, theory of evolution is well supported

Floating treatment wetlands are a manmade ecosystem that mimic natural wetlands (David J. Sample, 2013) and are used to increase the water quality of lakes (SWCD, 2017). The wetlands focus on the excess of nutrients in the water as well as it can increase the biodiversity throughout the lake (SWCD, 2017). These floating wetlands can help control the amount of nutrients throughout the pond using nutrient uptake. (SWCD, 2017). Floating treatment wetlands have been used because they can be used at a

have varying side groups on their structures. How do the reaction centers and photosystems differ between cyanobacteria and Chlorobi? Cyanobacteria have photosystems 1& 2 whereas Chlorobi only have photosystem 1. Cyanobacteria are able to absorb light at both short and long wavelengths whereas Chlorobi can only absorb light at long wavelengths. In the reaction center of cyanobacteria, oxygen is produced whereas the reaction center of Chlorobi does not generate oxygen. How do Green Bacteria

Snowball Earth is a long debated and controversial theory that a thick sheet of ice covers Earth in its entirety about 650 million years ago. The theory was first formed in the 1940s by Brian Harland after he learned of the existence of dropstones in the Arctic, and later discover that there are dropstones all around the world, even on the hottest continents and in the tropics. Harland hypothesized that ice spread to every continent with continental drift explaining the spread of dropstones, but

These is sufficient ammonia present of suppress nitrogen fixation. Important: in terms of generate nitrogen available to all organisms, the symbiotic associations very much exceed the free-living species with the exception of cyanobacteria. The world's growing population, depends ultimately on plants for food.They in turn depend on supply of nutrients, especially nitrogen compounds, in the soil. In world agriculture today, the natural processes for replenishing nitrogen used up by

Local pollution description General physical and chemical properties of Phosphorus What is the definition of Phosphorus? It is a highly reactive, poisonous, non-metallic element occurring naturally in phosphates, especially apatite. It exists in three allotropic forms, white, red and black. Physical Properties White phosphorous is white, waxy solid, giving off a greenish-white glow in the dark. It is spontaneously flammable when exposed to air and is deadly poison
