Photosynthesis Essay

What are chloroplasts, where did they come from and what are they good for? We all know that chloroplasts are the site for photosynthesis in plants and what makes plants autotrophic. It allows the plant to be known as the ‘producer’ in a food chain. Being such an essential part of the plant cell, the question arises, where exactly did it come from in the first place: has it been a part of the plant cell since the beginning of time or did it evolve from some other species, and how is it able to…

transport in spinach thylakoid membranes was the purpose of this lab. Photosynthesis is the process that routinely drives electron transport across the thylakoid membrane but can be impacted when additional factors are added. Two phases known as the light reactions and the Calvin cycle makeup photosynthesis. Plastoquinone shuttle, water oxidation, and NADP+ reduction are the major factors of the light reactions. Photosynthesis creates a proton gradient when pigments in the thylakoid membrane…

stomata are open during the day and photosynthesis takes place throughout the mesophyll cells. In comparison C4 plants, the CO2 is first incorporated into a 4-carbon compound. Their stomata are open during the day and photosynthesis takes place within the inner cells. C4 plants undergo carbon fixation and C3 plants undergo the Krebs cycle. This experiment is specifically for undergraduate students who have previous knowledge and background on the process of photosynthesis within C3 and C4…

vegetation, rocks, and soil (Visionlearning, 2016). The biological carbon cycle consists of the two main attributed to how plants live, Photosynthesis and…

Phosphorous play an important role in photosynthesis, respiration, energy storage and transfer, a plant doesn’t get the required amount it causes wilting leaves and Reduced fruit or seed production (O'HAGAN, 2016). The most important macronutrient is nitrogen, which is necessary for formation of…

Tropical Rainforest The Tropical Rainforest is a really interesting ecosystem. Did you know that the rainforest in southern Asia stretches 3,100 miles on 20,00 islands. Did You also know that some plants in the rainforest can help treat cancer. The tropical rainforest is home to some weird and endangered animals. Location Tropical Rainforest can be located in north South America,west Africa, southern Asia. It stretches from Peru and goes through the Amazon basin to the end of east Brazil.…

In “Plant Pigment,” by Shirley Raps and Jeffrey Harborne, two types of plant pigments are discussed: photosynthetic and nonphotosynthetic pigments. Photosynthetic pigments are responsible for absorbing light and transferring energy during photosynthesis. Among this group of pigments are chlorophylls, phycobilins, carotenoids, and reaction center pigments which causes plants’ green, blue, yellow and orange colors, respectively. Nonphotosynthetic pigments are used to attract insects for…

Many plants, such as Spinacia oleracea (Spinach) uses a process called Photosynthesis and Respiration to produce glucose and oxygen (O2). During photosynthesis, light, carbon dioxide (CO2) and water (H2O) are required to begin the process. Light is absorbed by the plant’s chlorophyll, while CO2 is absorbed through the stomata and H2O is absorbed by the cells of the root hairs. The equation for photosynthesis is 6CO2 + 6H2O  C6H12O6 (Glucose). Plants are able to absorb all colors of the visible…

and Krebs cycle which will cause the rate of metabolism and oxygen consumption to drop. It will also stop the production of ATP because NAD+ is used in the process of making ATP. 2. FRQ #2 a. In step 1, the key metabolic process is photosynthesis. In photosynthesis, the plants use carbon dioxide and light energy and produces glucose and releases oxygen. Carbon dioxide is broken down in the Calvin cycle and is produced into a 3 carbon sugar organic molecule. In step 2, the process is cellular…

Both a and b chlorophyll reflect green, which is why leaves appears to be green. Chlorophyll a is the pigment that interacts directly in the light requiring reactions of photosynthesis. Chlorophyll b is an accessory pigment and acts indirectly in photosynthesis by transferring photons that it absorbs to chlorophyll a. The chlorophyll contain a porphyrin ring, which is a stable ring-shaped molecule that is around electrons that move freely. Because they can move around…
