Photosynthesis Essay

The grand majority of plants use photosynthesis to obtain their energy to sustain. Plants perform photosynthesis by converting natural light into chemical energy *.In photosynthesis there are three different types of metabolic pathways for carbon fixation, this includes C3, C4 and CAM*. the CAM method was not observed in this lab. In the C3 method the plant converts CO2 to 3- phosphogylycerate which a 3 carbon which then enters the calvin cycle of photosynthesis *. While in the C4 methode CO2 is…

Introduction: Photosynthesis is the process by which plants absorb light and turn it into chemical energy. This energy, known as ATP is then used to fix carbon into glucose and oxygen is released as a by-product in the process. This lab focuses on light-dependent reactions that occur in chloroplast where pigments absorb light through photosynthesis. Objective: The purpose of this lab is to extract photosynthetic pigments from spinach leaves using paper chromatography. We will then measure…

dioxide in the atmosphere. In general, photosynthesis can be explained by the following formula: 6CO2 + 6H20 + ATP → C6H1206 + 602. Using the carbon dioxide present in their environment, water from their roots, and energy from sunlight, a plant is able to continue to grow and conduct cellular respiration through this process. But how exactly is it able to accomplish this? Well, let us being with the acquirement of ATP during the light dependent reactions. Photosynthesis occurs in the chloroplast…

Photosynthesis is an essential reaction that can be carried by chloroplast in the plant. (Campbell, pg. 175). Inside the chloroplasts, thylakoids contain pigments such as chlorophyll that play major role in photosynthesis. (Citovsky, Lecture 10). Photosynthesis are composed of light reactions and Calvin cycle. Light reactions required the light to initiate photoexcitation. Photoexcitation happened when the light strike on chlorophyll, the electron will be excited and transferred around the…

Multiple mechanisms are taken place in different types of plants to maintain the efficacy of photosynthesis. Plants fall within three categories: C3 plants, C4 plants, or CAM plants. C3 plants are the most common type of plant, C4 plants consist of mainly tropical plants, and CAM plants are succulents, such as cacti, which are found in arid and hot environments, such as the deserts. Each one of these plants have a specific enzyme in which it binds atmospheric carbon dioxide, with high affinity,…

light, red light and green light). A control cuvette was used to compare the rate of photosynthesis to those of the color transmittance cuvette. Before collecting the data we learned about plants and light absorption. We learned the reason why plants are green is because it emits green color and the other transmitted colors are absorbed by the plant. Using our new information we created a hypothesis for photosynthesis rates in white light versus no light and red light versus green light. In our…

Light Color and Photosynthesis Inquiry Introduction: Photoautotrophs are organisms that make their own food using sunlight such as plants. They acquire free energy through a process called photosynthesis. Through photosynthesis, sunlight provides the required energy to build carbohydrates from CO2 and H2O. This entire process takes place in the chloroplast which contains chlorophyll. Chlorophyll is the location that absorbs the sunlight and combines carbon dioxide and water in order to make…

Photosynthesis is the method of when the green plants and some different life forms use daylight to provide foods from carbon dioxide and water. Photosynthesis in plants includes the green color chlorophyll and produces oxygen as a result (What is Photosynthesis, P.1). Plants also use photosynthesis to create sugar. The sugars fuel a plant's roots, stems, and leaves so the plant can grow. It attempts to preform photosynthesis with leaves absorbing the sun’s light and then make the sugars within…

and Photosynthesis Respiration and photosynthesis are reactions that take place in the environment which complement each other, in the other case can be seen as a same reaction but happening in reverse of each other (Tang, 2005). In photosynthesis the ingredients/ requirement for it to place is water and carbon dioxide as they release oxygen and glucose as the products. Respiration to take place requires glucose and oxygen to yield carbon dioxide and water. Since the product of photosynthesis…

Wavelengths on Photosynthesis of Spinach Introduction The rate of photosynthesis changes based on the light that the spinach is exposed to. Knowing the wavelengths of light that spinach is most likely to photosynthesize would help in knowing what light to expose spinach to, to ensure that it grows the best. When exposed to varying wavelengths, rate of photosynthesis varies as well. Wavelengths of green light, red light, blue light, and light without a filter change the rate of photosynthesis,…
