I. Photosynthetic organisms are those who convert the sun’s energy through a process called photosynthesis. They are also referred to as autotrophs. These organisms include plants, algae, and some bacteria. These organisms take in energy from the sun and water. They then complete the steps of photosynthesis and produce oxygen and glucose. All living organisms on earth require oxygen to survive. Plants provide a continuous supply of oxygen for these organisms. Without plants, there would be less oxygen molecules present in the atmosphere, creating a potential threat to organisms that require oxygen.
a. The photosynthetic organisms use their internal makeup to carry out the process of photosynthesis. Their makeup is different from that of organisms such as animals. Plant and algae cells contain chloroplasts where photosynthesis takes place. The light reactions of photosynthesis drive the transformation of solar energy into ATP. The chloroplasts of plants contain pigment molecules (chlorophyll) which are responsible for capturing the light from the
The way to get the largest amount of energy rom algae would be to eat it directly. If the algae would have been fed to the cow first, the energy would have also been consumed by the cow. The energy produced by the algae would then be used directly by the cow’s cells. It would use the energy to perform its everyday functions much like a human would. This means that when the human were to consume the cow, there would not be any energy left from the algae. When referring to the pyramid of life, it can be seen that the sun has the most energy. This is the reason why photosynthetic organisms are next on the pyramid. They get energy directly from the sun where as other organisms must get energy from other resources. If the human were to eat the algae instead, they would get a larger amount of energy. This is because according to the pyramid, plants have a larger amount of stored energy than cows, also known as
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.
The bottom of the chain and the trophic level that depends upon by all others is the primary producers. These primary producers consist of autotrophs, which are capable of deriving their food and energy source without consuming organisms or substances taken from other organisms. In the Arctic lake of Alaska, one of it’s primary producers consists of aquatic plants and algae. These aquatic and algae contain chlorophyll, which means that they can use light energy from the sun to synthesize glucose and other organic compounds, that they can use for cellular respiration and building material for growth. In other words, called photosynthesis. Photosynthesis requires light energy, but some autotrophs use chemosynthesis, which means they can convert nutrients to organic compounds without light in the presence.
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.
What organisms perform it? Most plants, algae, and cyanobacteria perform photosynthesis; such organisms are called photoautotrophs.
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.
Photosynthesis is a series of light driven reactions that convert energy poor compounds such as carbon dioxide and water to energy rich sugars [1] such as glucose. The process generate an electron gradient across the membrane of a chloroplast, which is used for ATP synthesis, and simultaneously produces electrons used to make NADPH, using NADP+ as an energy carrier[2]. Crudely put, it is the method by which autotrophic plants make their own ‘food.’
They are connected in series by an electron transport chain and they differ in the organization of light harvesting systems and pigment compositions. The two pigments found in the photosystems of green algae are chlorophylls and carotenoids (Green and Durnford, 1996). Chlorophyll is the principal pigment that functions to trap light energy and it is present in two forms; chlorophyll a (Chl a) and chlorophyll b (Chl b), and they can be distinguished based on their absorption spectra. Chl a has an absorption maxima of 659 nm and 429 nm while Chl b has an absorption maxima of 642 nm and 455 nm (Zscheile and Comar, 1941). The presence of two pigments with differing absorption maxima functions to broaden the range of light that can be absorbed and used for photosynthesis. Carotenoids are also present in the photosystems and in addition to serving as light harvesting apparatus, the carotenoids are involved in energy dissipation in the presence of excess light (Santabarbara et al.,
“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).
In some way, shape, or form energy is one of the several reasons why there is an existence of life on earth. Cellular respiration and Photosynthesis form a cycle of that energy and matter to support the daily functions that allow organisms to live. Photosynthesis is often seen to be one of the most important life processes on Earth. Photosynthesis is a process by which plants use the energy of sunlight to convert carbon dioxide and water into glucose so other organisms can use it as food and energy. It changes light energy into chemical energy and releases oxygen. This way organisms can stay alive and have the energy to function. Chlorophyll is an organelle generally found in plants, it generates oxygen as a result too. As you can see without
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...
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 is so important that, without it, there wouldn’t be life on Earth. Photosynthesis is the process in which light energy is transformed into chemical energy. During photosynthesis, the chemical energy is used to obtain organic compounds from carbon dioxide. Carbon dioxide and water are the raw materials. The main energy source is the sunlight absorbed by the plant. Then oxygen and glucose are produced. This is what facilitates cellular respiration in humans. During that process, water is used and then O2 is released into the atmosphere. These organic compounds are important to plant life because it is what helps a plant grow and fully develop. Plants are photoautotrophs meaning they feed of themselves using the sun. Plants aren’t the only ones that benefit from this magnificent process. Animals benefit from this because they consume the plants and then all the molecules obtained are then converted into their own organic molecules. These organic molecules are the main energy source for the animals.
Photosynthesis is the process in which living cells from plants and other organisms use sunlight to produce nutrients from carbon dioxide and water, the image below “Diagram of photosynthesis 1,” helps show this process. Photosynthesise generally creates oxygen as a by-product through the use of the green pigment, chlorophyll, found in the plant that helps this reaction occur. “Photosynthesis provides us with most of the oxygen we need in order to breathe. We, in turn, exhale the carbon dioxide needed by plants,” (factmonster,2017). This is able to show us why photosynthesis is so greatly needed to occur through plants in order to give one another essentials needed for continuity of life. “Plants perform photosynthesis because it generates the food and energy they need for growth and cellular respiration,” (photosynthesieeducation, 2016).
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...
