Light has a wave nature and particle nature. The smallest parts or units of light are called photons and the amount of photons absorbed per unit time determines the brightness of light. Wavelengths are a certain amount of energy each photon possesses as they vibrate. Chlorophyll reflects the wavelengths green part of the light spectrum because it is green and the plants that contain chlorophyll are green as well.
This article may not be reliable because there was no date or author noted. This article clearly examines in what form light is absorbed and the process thereof.
Article 2:
Photosynthesis converts light/radiant energy to chemical potential energy. The raw materials needed for this process to occur are light energy, water and carbon dioxide in order to make glucose. Light absorbed gives chlorophyll the green pigment as it absorbs red and blue light therefore making these two colours invisible to the human eye as the green is not absorbed. This means that the blue and red light are used for photosynthesis.
This article is reliable in that it has been recently updated on the website therefore any flaws or inaccuracies would have been corrected then as the process of photosynthesis does not evolve, but rather, the plant evolves and adapts itself for this process. This article clearly states that although not all parts of the light are used, it is still needed by the chlorophyll molecules and gives the molecules their characteristic green pigment.

Photosynthesis depends on light absorbed by the chloroplasts in the leaves. Nutrients would not be created by photosynthesis if it weren’t for the absorption of light. It is said that early aquatic bacteria photosynthesize using s protein complex in halobacteria- in their ...

The majority of life on Earth depends on photosynthesis for food and oxygen. Photosynthesis is the conversion of carbon dioxide and water into carbohydrates and oxygen using the sun’s light energy (Campbell, 1996). This process consists of two parts the light reactions and the Calvin cycle (Campbell, 1996). During the light reactions is when the sun’s energy is converted into ATP and NADPH, which is chemical energy (Campbell, 1996). This process occurs in the chloroplasts of plants cell. Within the chloroplasts are multiple photosynthetic pigments that absorb light from the sun (Campbell, 1996).
... in the chloroplasts in some of their cells. Chlorophyll allows the energy in sunlight to drive chemical reactions. Chloroplasts act as energy transducers, converting light energy into chemical energy. So as the plant has more light the chlorophyll inside the chloroplasts can react faster absorbing in more light for food and energy.¡¨ So this shows my prediction was correct for in my experiment and shown in my result table and graph the more light intensity there is on a plant the higher the rate of my photosynthesis will be. My prediction is very close to what I said the results will be so my prediction was correct and has been proven to be correct in my result table, graph and now explained again in my conclusion.
Autotrophs, can build organic compounds from simple molecules such as water and carbon dioxide and their type of feeding is called autotrophic nutrition. While they are building complex molecules, they need large amounts of energy. They are divided into two groups according to their source of energy: chemoautotrophs and photoautotrophs. Chemoautotrophs can synthesize organic compounds from CO₂ AND H₂O by using inorganic oxidation energy and they do not require sunlight. However, photoautotrophs, including green plants, produce sugar and O₂ from CO₂ and H₂O by using sunlight. The green pigment which absorbs the light is called chlorophyll and this process is called photosynthesis.
The green pigment in the chloroplasts are called chlorophyll and that is what absorbs light for a process called photosynthesis. Photosynthesis is a process to make “plant food” and it takes place in the chloroplasts. The process needs sunlight, water, oxygen and carbon dioxide to create sugar. The food created in photosynthesis helps the plant grow and survive, without it, the plant would not have energy or food to do simple tasks. Furthermore, the plant takes less oxygen and releases more oxygen during photosynthesis. In addition, like I said earlier chloroplasts have chlorophyll in them and the chlorophyll gives the plant the unique green color. To summarize, the chloroplasts are vital to plants because they create food from a process called
Photosynthesis is one process of energy capture for living organisms. The formula for photosynthesis is 3CO2 + 6H2O + light C3H6O3 + 3O2 + 3H2O. Basically, during this process, light energy is captured and converted into chemical energy, but it goes much deeper than that. First, light is captured by chloroplasts that contain pigments that capture different photons of light and then reflect different colors. The pigments include: chlorophyll, which absorbs blue and red wavelengths but reflect green; phycobilins, which absorbs blue, green, and yellow,
Where do they occur? Light reactions take place in the thylakoid membranes of the chloroplast.
In the light intensity experiment, tubes of buffer solution, chloroplast, water and DPIP were placed in different intensities of light to determine how light intensity affects the reaction rate of photosynthesis. The reaction rate was measured by absorbance values in five-minute increments for 30 minutes. The tubes were placed at 24 cm away, 30 cm away, 49 cm away, and completely dark. The tube that was closest to the light had the smallest absorbance value, while the dark tube had the highest value. As the light intensity increases, the absorbance value decreased. In the action spectrum experiment, 10 aspirated spinach leaves and sodium bicarbonate solution were mixed together in beakers then each beaker was placed in different light boxes.
Photosynthesis is a highly important process that takes place in plants primarily because without it life on this planet would not be able to function properly. “It produces the oxygen we breathe and the food we eat” (Harbinson). Without photosynthesis, life would not be able to sustain itself and our planet would be a barren wasteland. The Photosynthetic process converts light energy into chemical energy. The energy that’s created through the process then later is used to help fuel the organism’s activities. This process can be significantly more complicated than it sounds with different stages and many steps.
During photosynthesis, solar energy in the form of light is absorbed. This light drives charge separation in the reaction centres of photosystems I (PSI) and II (PSII), initiating electron transport which then leads to the oxidation of
Photosynthesis in simpler turns is the ability of a live plant to carry on its chemical process by the use of light energy. Photosynthesis can not take place when there is absolutely no light, instead it stores the light it captures during the day, and uses it when needed. Photosynthesis can take place in land plants and aquarian plants such as algae. There are many factors that influence the ability of a plant to go through photosynthesis, such as light, the color of light and amount of water and or light.
Photosynthesis is essential for the reason that all living things depend on it in some way. It is the main mechanism for transferring energy from sunlight into a more useful form to be used by plants and animals. The process of photosynthesis simply will not occur if any of the materials needed are not present. Water has proven to be the most crucial element needed in photosynthesis as it has devastating effects when not present in the required amounts.
Photosynthesis and cellular respiration help sustain life on planet earth as both are metabolic processes in their own way. Photosynthesis is the process by which plants and other organisms use energy from the sun to form glucose from water and carbon dioxide. From there, glucose is then converted to ATP by way of cellular respiration. To convert nutrients that are biochemical energy into ATP, a process such as cellular respiration that has reactions needs to take shape in the cell of an organism, releasing waste products at the same time. For the continuous energy cycle that tolerates life on Earth as we know it Photosynthesis and Cellular respiration very essential. They have a few stages where energy and various connections occur within the eukaryotic cell. Cellular respiration takes place in the lysosome, an organelle that is found in the cytoplasm of eukaryotic cells. It uses enzymes to break down biomolecules including proteins, nucleic acids, carbohydrates, and lipids. Photosynthesis involves the chloroplasts, which contain pigments that absorb the sunlight and then transfigure them to sugars the plant can use. Those specific processes are crucial in how far and diversified evolution has
The photosynthetic pigments are important because they donate the electrons needed to start the sequence of reactions
The topic I chose for my paper is Photosynthesis and how it benefits us in our everyday lives. My major is Biology with a minor in business and it is very important time to find out what living plants are all about and how they affect us. Photosynthesis, what most humans don't know, is very important to our life. It is important because plants make their own food and past their energy down to humans when we eat the nutrients that the plants have in them. Without nutrients, we humans would not be able to function properly. Photosynthesis also creates fresh air so we can breathe. The main point in my research is to inform people what photosynthesis is, what's the process and how it works, and all the things that make photosynthesis
Photosynthesis is a key contributor to all living things; photosynthesis provides the oxygen, food, and nutrients that help all living things stay healthy and alive. Photosynthesis converts solar energy into the chemical energy of a carbohydrate. Photosynthetic organisms, including land plants, algae, and cyanobacteria, which are called autotroph...
