Most Cyanobacteria, like the ones in the model, are capable of nitrogen fixation. In order to fuel their growth cyanobacteria, rely on fixed forms of nitrogen such as ammonia and nitrate. Cyanobacteria tends to become very abundant in warm, shallow, undisturbed surface water. These conditions allow for them to form blooms that produce surface scum. They can also produce a toxin called microcystins that makes the water unsafe for consumption.
There are two types of photosynthetic processes: oxygenic photosynthesis and anoxygenic photosynthesis. Oxygenic photosynthesis is the most common and is seen in plants, algae and cyanobacteria. During oxygenic photosynthesis, light energy transfers electrons from water (H2O) to carbon dioxide (CO2), which produces carbohydrates. In this transfer, the CO2 is "reduced," or receives electrons, and the water becomes "oxidized," or loses electrons. Ultimately, oxygen is produced, than released, along with carbohydrates used for food.
They break down dead biological matter and waste products and convert them into useable energy; returning important materials to the environment. Decomposers are a particular important feature in the Great Barrier Reef considering the heavy bio-load. Main decomposers inside the reef include bacteria, sea cucumbers, some species of snails, crabs and bristle worms. Bacteria sis not only vital for the Great Barrier Reef’s food web, but is also said by scientists that it could be the key to keeping the coral healthy and able to withstand the impacts of global warming. Dr Tracy Ainsworth stated “it is very likely that these microorganisms play a vital role in the capacity of coral to recovering from bouts of bleaching caused by rising temperatures.” Corals rely on these good bacteria’s crucially although we don’t yet understand these microbe’s ell enough to know how they influence coral survival, which is vital in maintaining the food web of the Great Barrier Reef.
Elodea is a type of rooted plant with multiple branches (Elodea). Elodea is known as a weed located in parts of Australia, Africa, Asia and Europe, but is known to be popular in Washington’s lakes, ponds and rivers (Native Freshwater Plants, 1994). Photosynthesis involves light energy converting to sugar while respiration burns the sugars produced in photosynthesis in order to help the plant grow and reproduce (Whiting, 2014). The equation for photosynthesis is 6CO2+ 6H2O⇢C6H12O6+ 6O2. In other words, carbon dioxide, water and light are the reactants, and the products of photosynthesis are glucose and oxygen.
A question that many wonder about is why is phytoplankton important? Plankton is revealed by ocean color and help show scientists where ocean currents provide nutrients for plant growth. They also help show where pollutants are poisoning the ocean preventing plant growth and where changes in the climate of the ocean are occurring. Plankton is also the foundation of the oceans food chain. As phytoplankton begin to grow and multiply, small fish eat them, then the larger animals begin to eat those smaller animals.
DIY - What Is Life? How can you determine whether something is alive, dead, or non-living? Whenever we speak of life, we must think in terms of cells. Even though we cannot see cells without a microscope, they are the basic unit of life and they exhibit all of the characteristics of living organisms. They can exist individually, as do bacteria, or they may work together, taking on specialized tasks to create a more complex organism.
Electromagnetic spectrum: its energy that travels in waves, a broad spectrum from long radio waves to short rays and we can only detect a small scale of the spectrum which is called visible light. Aquatic VS terrestrial: In terrestrial ecosystems plants provide the oxygen and the base of almost all food webs. In aquatic ecosystems those roles are carried more by various types of algae and plankton. 2- Compare and contrast these types of eyes: Microvilli VS Cilia : Cilia : is a microscopic hair like structure that are found is almost all mammalian cell. Microvilli: microscopic cellular membrane which increase surface area of the cell, it has couple of functions such as cellular adhesion, absorption and secretion.
All living cells are divided into two distinct categories, those which lack a membrane bound organelles and those that have membrane bound organelles. These are called prokaryotic cells and eukaryotic cells, respectively. “Organelle” is the word used for the specialized subunit that is within a cell which has a specific function. Mitochondria is one such membrane bound organelle. The word mitochondrion describes its size and shape and comes from the New Greek for “mitos”, which is the word for “thread" and “chondrion”, which is the word for "small grain".
photosynthesis and cellular respiration are extremely important in the cycle of energy to sustain life simply because nutrients would not metabolize in a productive manner. Both have numerous stages in which the process of energy occurs, and relationships with organelles located in the eukaryotic cell. Photosynthesis is a process by which green plant and other organism manufacture their food using sunlight to synthesize foods from carbon dioxide and water while cellular respiration is the oxidation of organic compounds that occurs within cells, producing energy for cellular processes. Photosynthesis occurs within organelles called chloroplasts. These organelles can absorb light, and are located inside of leaves.
The Effect of Sugar Concentration on CO2 Production by Cellular Respiration in Yeast Introduction In this lab, our main focus was to find how sugar concentration affect yeast respiration rates. This was to simulate the process of cellular respiration. Cellular respiration is the process that cells use to transfer energy from the organic molecules in food to ATP (Adenosine Tri-Phosphate). Glucose, CO2, and yeast (used as a catalyst in this experiment) are a few of the many vital components that contribute to cellular respiration. Sugar/ glucose is an important carbohydrate that can be made during photosynthesis from water and carbon dioxide, using energy from sunlight.
