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. The basics of the process known as photosynthesis are very straightforward but can become very complex once dissected. As a follow …show more content…
Water plays a key role in photosynthesis and it’s stated that “Water is a uniquely hardy molecule to be involved in photosynthesis” (Castelvecchi).Water acts as both an oxygen provider as well as an electron feeder. During the photosynthetic process, six Co2 or more commonly known as carbon dioxide molecules and six H2O, or water molecules react to sunlight, which then forms one glucose molecule and six oxygen molecules. The role water plays in this is takes that water molecule and releases oxygen into the air in a form of oxygen …show more content…
One of these vulnerabilities is heat stress and how it affects the photosynthetic process. According to a study, “Photosynthesis is particularly sensitive to heat stress and recent results provide important new insights into the mechanisms by which moderate heat stress reduces photosynthetic capacity” (Sharkey). Heat stress can be highly inconvenient to the photosynthetic process since is can decrease the photosynthetic rate near to zero. What happens is “Moderate heat stress can stimulate dark reduction of plastoquinone and cyclic electron flow in the light” (Sharkey). This can be harmful to the plants as it can completely jeopardize the whole
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).
Photosynthesis consists of the following equation: Sun light Carbon dioxide + Water = = == == ==> Glucose + Oxygen Chlorophyll Chlorophyll is a substance found in chloroplasts, found in the cells of leaves.
Before learning about photosynthesis, I thought this was just a way for plants to grow, not knowing the full detail that goes on inside the plant for it to grow. So, after learning about what photosynthesis is and how it truly works, it is something that is remarkable and how plants are really the only living thing that uses this process. 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, sunlight is absorbed through chloroplasts which contain chlorophyll or better known as the leaves of the plant. 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 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
Water has a great number of roles in living organisms, this is largely to do with the structure and covalent bonding in a single water molecule, and between water molecules. Around 75% of the earth is covered in water, and it is reffered to as the most important Biochemical. Its chemical symbol is: H2O In a water molecule there are two bonding pairs and two non-bonding pairs of electrons. These four pairs of electrons repel one another, forming a tetrahedral pattern.
“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.
Photosynthetic pigments are essential for life because they allow photosynthesis to occur by capturing sunlight which is then used alongside carbon dioxide and water to form organic compounds such as glucose and oxygen. The pigments allow the conversion of light energy to chemical energy which other organisms can benefit from. Oxygen is utilised by other organisms in aerobic respiration. The different pigments present in the chloroplasts allow a wide variety of wavelengths of light to be absorbed for efficient photosynthesis and provide colours to the plant to attract pollinators.
Photosynthesis, undoubtedly, is one of the most beneficial chemical reactions, for one simple fact. It keeps us alive. It is a simple, unassuming reaction, 6 CO2+ 6 H2O → C6H12O6+ 6 O2. So, it is just carbon dioxide and water reacting and turning into glucose and oxygen. “But,” you may ask, “Why is it so important?” It is because it takes our used air (CO2) and turns it back into the air we breathe (O2). Photosynthesis also turns our extra carbon dioxide into oxygen, reducing global warming's effects.
Photosynthesis begins when light strikes Photosystem I pigments and excites their electrons. The energy passes rapidly from molecule to molecule until it reaches a special chlorophyll molecule called P700, so named because it absorbs light in the red region of the spectrum at wavelengths of 700 nanometers.
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,")
Photosynthesis is a cycle plants go through converting light into chemical energy for use later. Photosynthesis starts in the chloroplasts, they capture chlorophyll, an important chemical needed for photosynthesis. Chloroplasts also take water, carbon dioxide, oxygen and glucose. The chlorophyll is taken to the stroma, where carbon dioxide and water mix together to make
