The Process of Photosynthesis

Plants are one of the many wonders of the world. They are considered autotrophs; they do not rely on outside sources for their food. They create their own food by the process of photosynthesis. Photosynthesis is when green plants and certain other organisms use light energy to change carbon dioxide and water into the glucose. In so doing, photosynthesis provides the basic energy source for almost all organisms. An extremely important byproduct of photosynthesis is oxygen, on which most organisms depend.
Photosynthesis occurs in green plants, seaweeds, algae, and some bacteria. These organisms are virtual sugar factories, producing millions of new glucose molecules per second. Plants use most of this glucose, which is a carbohydrate, as an energy source to build leaves, flowers, fruits, and seeds [1]. They also convert the produced glucose into cellulose, which they use as structural material in their cell walls. Most plants produce more glucose than they use, however, and they store it in the form of starch and other carbohydrates in roots, stems (Figure 1), and leaves (Figures 2 & 3). The plants can then draw on these reserves for extra energy or building materials. Each year, photosynthesizing organisms produce about 170 billion metric tons of extra carbohydrates, about 30 metric tons for every person on earth [2].
Photosynthesis has far-reaching implications. Like plants, humans and other animals depend on glucose as an energy source, but they are unable to produce it on their own and must rely ultimately on the glucose produced by plants. Most importantly, the oxygen humans and other animals breathe is the oxygen released during photosynthesis. Humans are al...

Experiment #1: The purpose of this experiment is to investigate the effects of baking soda and light intensity on the rate of photosynthesis of green spinach leave through the observation of floating disk.
We depend on plants to obtain our oxygen. Plants produce glucose that assists in its living and growing and we contribute by releasing carbon dioxide. In order for us to live, we need the oxygen that plants produce by making glucose.
The greater overall rate of absorbance change in all chloroplast samples (Figure 1) confirms role of chloroplasts’ in photosynthesis. However, the use of the supernatant sample as a negative control was expected to yield no activity, which was shown to be untrue (Figure 1) and is contributed to the contamination of the supernatant sample with chloroplast. The fragile envelope of the chloroplasts can be eas...
So, after learning about what photosynthesis is and how it truly works is something that is remarkable and how plants are really the only living thing that uses this process. Such as photosynthesis is the process of taking in carbon dioxide (CO2), which is a gas that is exhaled from animals and goes into the air and is absorbed into a plant, water (H2O) which is absorbed through the roots of a plant or known as capillary action, sun light is absorbed through chloroplasts which contains chlorophyll or better known as the leaves of the plant. Sun light is what helps break down and rearranges the atoms of these two, which produces sugars (glucose, C6H12O6), and this is photosynthesis at its finest. With the photosynthesis process the plant can create a by-product known as oxygen gas which is released through the little pores into the atmosphere (Simon, Dickey, Hogan & Reece, n.d.). Photosynthesis is something that helps the plants to grow but it is also very beneficial to us for the fact that we need to breath oxygen to maintain our functions of life. Plants produce an abundant supply of energy that is stored because they are what I would like to call savers/hoarders. Plants store the extra energy that they produce into different things such as potatoes, carrots, and other different types of food in which we use to
product and glucose levels. Plants trap the energy in sunlight using chlorophyll, a light trapping pigment found in leaf plant cells. It then uses carbon dioxide which enters the plant through small holes found. on the underside of the leaf called stoma and water which enters the

Chlorophyll in the cells in the palisade layer absorb light for photosynthesis. The plant releases the oxygen created in photosynthesis back into the air but it uses or stores the glucose for energy, respiration, growth and repair. The leaves and plants are also specially adapted for photosynthesis in their structure and cell alignment.

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
“Photosynthesis (literally, “synthesis from light”) is a metabolic process by which the energy of sunlight is captured and used to convert carbon dioxide (CO2) and water (H2O) into carbohydrates (which is represented as a six-carbon sugar, C6H12O6) and oxygen gas (O2)” (BioPortal, n.d., p. 190).
An Experiment to Investigate the Effect of Light Intensity on the Rate of Photosynthesis. Introduction Photosynthetics take place in the chloroplasts of green plant cells. It can produce simple sugars using carbon dioxide and water causing the release of sugar and oxygen. The chemical equation of photosynthesis is: [ IMAGE ] 6CO 2 + 6H20 C 6 H12 O 6 + 6O2 It has been proven many times that plants need light to be able to photosynthesize, so you can say that without light the plant would neither photosynthesize nor survive.
Photosynthesis is a process in plants that converts light energy into chemical energy, which is stored in bonds of sugar. The process occurs in the chloroplasts, using chlorophyll. Photosynthesis takes place in green leaves. Glucose is made from the raw materials, carbon dioxide, water, light energy and oxygen is given off as a waste product. In these light-dependent reactions, energy is used to split electrons from suitable substances such as water, producing oxygen. In plants, sugars are produced by a later sequence of light-independent reactions called th...
Photosynthesis is a process in which plants and other organisms convert the light energy from the sun or any other source into chemical energy that can be released to fuel an organism’s activities. During this reaction, carbon dioxide and water are converted into glucose and oxygen. This process takes place in leaf cells which contain chloroplasts and the reaction requires light energy from the sun, which is absorbed by a green substance called chlorophyll. The plants absorb the water through their roots from the earth and carbon dioxide through their leaves.
According to scientists, photosynthesis is “the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.” ("pho•to•syn•the•sis,")
Without plants, none of this energy could be produced and the herbivores that humans consume would not exist. The cells in plants also undergo cellular respiration, which creates the byproduct oxygen.
