Photosynthesis Essay

then dropped even lower before rising back to stagnant levels. This may be because there may have been a slight ventilation in the room at around 125 seconds. 2. What is the role of carbon dioxide in photosynthesis? What is its role in cellular respiration? The role of carbon dioxide in photosynthesis is that it is used by plants to create glucose and water which is what is used as food for the plant and in turn creates oxygen. After the oxygen is formed carbon dioxide is created from this…

Plants get mass from the air, specifically carbon dioxide. The results from both VonHelmont's experiment and the radish seed experiment support this idea. In VonHelmont’s experiment, the plant gained 164 pounds in 5 years while the soil only lost 2 ounces in weight.These results reveal that a plant does not receive its mass from soil. The roots of the plant absorbed water from the soil in order to photosynthesize causing the soil to lose 2 ounces overtime. In the radish seed experiment, the…

From prior knowledge, we know that when you add CO2 (carbon dioxide) to bromothymol blue the water will turn green, when you add O2 (oxygen) the water will turn blue. The experiment we investigated is how does the amount of light the plant receives affect the color of the water. We took three test tubes with water and bromothymol blue, two of them had elodea plants in them one of them the control did not. One of the test tubes with the elodea plant in a dark cabinet where no sunlight could reach…

Pattern, Problem, Correlation: Algae are very extensive, and have proven to be very beneficial to our environment. They are a “diverse group of predominantly aquatic organisms that account for almost 50% of the photosynthesis that takes place on Earth” (Moroney et al. 2009). Due to this prevalence of algae, it is important to know its uses. Firstly, “algae are proposed to play a role in the global carbon cycle by helping remove excess carbon dioxide from the environment” (Moroney et al. 2009).…

Because of past issues with artificial photosynthesis, the ability to keep the Silk Leaf “alive” is something to keep an eye on. There is no promise in self sustainability of the chloroplasts within the leaves, so this means that there must be a large source of leaves if brought into space. If used…

on Earth comes from the Sun however, only a certain group of organisms can harness the sun’s energy and convert it into sugars and carbohydrates. These organisms are known as Autotrophs and they are primary producers. Autotrophs usually conduct photosynthesis to use the sun’s energy, but some can use chemical energy using oxidation. Other organisms are consumers and may be consumers of different trophic levels going up the trophic pyramid. Between these trophic levels, only about 10% of energy…

living things, and stored as well. For example, phytoplankton soaks up energy by using photosynthesis (non-living things to living). Carbon can move through a short period of time…

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…

1.0 Introduction The Daintree rainforest, a region located in tropical far north Queensland, is the biggest continuous rainforest in Australia (refer to figure 1 for location on map). Around 1,200 square kilometres in size, the Daintree rainforest is home to fast flowing streams and waterfalls to mountain ranges and dense rainforests, along with a variety of landscapes and a range of different and native flora and fauna. The forest is along the north coastline of the Daintree river, with…

so they produce their own foods from nonliving sources. Like all plants the Chrysanthemum belliam main source of food is glucose, a simple carbohydrate. This simple carbohydrate (with its waste product oxygen) is a product of photosynthesis. In simple terms, photosynthesis is using the sun’s light energy to produce food - glucose. However, it’s a much more complex chemical reaction than that description. The process, which takes place in the chloroplast, uses solar energy to convert carbon…
