Mr. Euglena is trapped in a crowded area and must be able to travel to a less crowded area to live. The biological processes of photosynthesis and aerobic respiration allow him to do this. Because of these two processes, energy is given to the kinetosome, which then allows the flagellum of Mr. Euglena to move him to a less crowded area.
Mr. Euglena is aware that he must move to less crowded area in order to live. However, he waits patiently for the sun to gradually move higher in the sky. He believes that if he waits for enough sunlight, the process of photosynthesis will occur in his chloroplasts to make molecules of glucose. This is the beginning of the process of photosynthesis, which is the production of glucose in the chloroplasts of cells.
In his situation, Mr. Euglena waits for the sun to get higher in the sky because he needs enough sun light to convert into energy in photosynthesis. The light reaction is the first stage of photosynthesis which requires light. With the sunlight, four pigments in his chloroplasts absorb the sunlight. These four pigments are carotenes, xanthophylls I and II, and chlorophyll b. These pigments will then convert the sunlight to chemical energy, which then transfers to chlorophyll a. Chlorophyll a then splits six water molecules (6 H2O) into twelve hydrogen atoms (12 H) and three oxygen molecules (3 O2). The coenzyme NADP then holds the product of twelve hydrogen atoms (12 H) as 6 NADPH2 to carry to the next process. The three oxygen molecules (3 O2) are then released into the air as a byproduct. The light reaction must happen a second time in order for the second phase of photosynthesis, the dark reaction, to occur. The same cycle of the light reaction then takes place. The result of two lig...

...or the dark reaction and the brake for aerobic respiration. This allows for many ATPs to be produced, allowing the kinetosomes to anchor the flagellum of Mr. Euglena through the cell membrane. This anchor enables the flagellum to function, which will move Mr. Euglena to a less crowded area in order to live.
In short, Mr. Euglena will survive the tough situation of a crowded area by waiting for the sun to rise higher in the sky. By waiting, his chloroplasts will absorb sunlight allowing photosynthesis to occur. When photosynthesis produces a glucose molecule, the glucose molecule is transferred to the cristae for the process of aerobic respiration. Aerobic respiration then makes ATPs which will release energy to the kinetosome. This energy will enable the kinetosome to anchor the flagellum so that it may function to move Mr. Euglena to a less crowded area to live.
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).
And different temperature cause different speed of growth. Shown by results, when euglenas in fridge and incubator, the speed of growth was obvious slower than when euglenas in room temperature. Therefore, extreme temperature is not good with the growth of euglenas. Low incubation temperatures favor growth in Euglena whereas high incubation temperatures favor cell division. Maximal growth rate occurs at 25 °–30 °C and maximal accumulation of cellular material occurs at 13.3 °–17 °C. The dry weight of Euglena at 25 °–28.5 °C is less than half of what it is at 13.3–17 °C. (Buetow, 1962) synthesize the experiment and theory, it is suited for euglena to live in room temperature which at 25-30
... 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.
Photosynthesis can occur in any green part of the plant. This green part contains chloroplasts. Chloroplasts separate photosynthesis and other cellular activities. The cytoplasm like liquid, stroma, in chloroplast consists of ribosome, DNA, and enzymes which takes part in photosynthesis. There are two stages in photosynthesis: light dependent and light independent. In light dependent stage, by using light energy water is broken into hydrogen and oxygen. In light independent stage, hydrogen reacts with CO₂. Also, water is reformed. This stage both happens when it is dark or light.
The basics of the process known as photosynthesis are very straightforward but can become very complex once dissected. As a follow
Mitochondria and chloroplasts have the likenesses with microscopic organisms that prompted the endosymbiont hypothesis. This hypothesis expresses that an early a castor of eukaryotic cell inundated an ocygen utilizing nonphotosynthetic prokaryotic cell. In the long run, the overwhelmed cell shaped an association with the host cell in which it was en shut, turning into an endosymbiont. Through the span of advancement the host cell and its endosymbiont converged into a solitary living being, an eukaryotic cell with a mitochondrion. As opposed to being limited by a solitary layer like organelles of the endomembrane framework, mitochondria and common chloroplasts have two layers encompassing them. Evidence the hereditary overwhelmed prokaryotes
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 contrast, eukaryotic organisms typically include (but are not limited to) membrane-bound organelles such as the nucleus, mitochondria, endoplasmic reticulum (E.R.), golgi body, lysosome and peroxisome. The main defining difference between a eukaryote and prokaryote is that the latter does not contain a nucleus or any such organelles. Such a definition, however, can be argued to be a poor discriminator between organisms of Eukarya and Prokarya, because it describes only what prokaryotes are lacking, not what they fundamentally are. This essay aims to detail a more comprehensive definition of why these two kingdoms are so different from each other. A key example of this thinking is that, while prokaryotes are often singly responsible for metabolic processes, reproduction and cell repair, eukaryotes are often highly specialised in order to perform certain functions and rely upon other cells to fulfil different functions. For exa...
Photosynthesis is the process by which plants and other organisms such as photosynthetic bacteria, algae and protists make their food. All organisms that undergo photosynthesis can be called photoautotrophs. In the food making process, the organism uses sunlight energy trapped by leaves and converts it into chemical energy. This chemical energy is then utilised as a drive force for the synthesis of organic products such as glucose. ¹The best known form of photosynthesis is the one carried out by higher plants and algae, as well as by cyanobacteria and their relatives, which are responsible for a major part of photosynthesis in oceans, Wim Vermaas 1998. The photosynthetic process can be written in a simple equation; 6H2O + energy (eˉ) 6CO2 -> C6H12O6+ 6O2. In anoxygenic photosynthesis however, light energy is used by other types of bacteria but in their case O is not a product. At a molecular level, these organisms use CO2 and H2O along with the energy obtained from the sun to undergo a series of complex reactions before they arrive at the end product of the desired carbohydrate.
Photosynthesis consists of two things, Light Dependent Reactions and Light Independent Reactions which both take place inside of chloroplast cells. Photosynthesis is the process in which autotrophs, organisms that make their own food, use sunlight to process their own food. Water, sunlight, and oxygen are all substances that undergo change during photosynthesis and oxygen and glucose are the products of the reactants. Chloroplasts, the cell where photosynthesis takes place, contains thylakoids, the granum, and the stroma.
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 has 4 factors that it needs to occur: chlorophyll, water, carbon dioxide and sunlight (radiant energy), these also influence the rate of photosynthesis depending on the amount. In this investigation the factor of (sun)light will be investigated. We know already that light is necessary for photosynthesis to occur but it will be proven by an experiment and literature reviews that it is indeed necessary.
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
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,")
