Measuring The Rate Of Photosynthesis Of Pondweed Elodea Sp

483 Words2 Pages

The experiment on photosynthesis is conducted to measure the rate of photosynthesis of the pondweed Elodea sp. The experiment observed the effects of light intensity and water temperature on the rate of evolution of oxygen from the weed. The oxygen released is determined by the released of the bubble of the weed in a minute. Photosynthesis is a chemical reaction that crucial for every plants. The plants synthesized their own food through the reaction of photosynthesis. The process involved the conversion of the sunlight energy to the chemical energy. This process is associated with the function of the green pigment called chlorophyll. The plant traps the light energy to produce carbogydrates . The photosynthesis process needs the presence of water and carbo dioxide to released sugar and oxygen.The carbohydrates is converted into ATP that is essential in all living things. 6h20+6co2=c6h12o6+6o2 …show more content…

There are two reaction in photosynthesis which are light-dependent reaction and light-independent reaction. Both of these reaction s are affected by the presence of the light. This is because in light-dependent reaction, light energy is needed to produce ATP and reduce electron carrier NADPH. This reaction occurs in the thylakoid membrane of chloroplast. In contrast, light-dependent reaction does not reuires lght energy. This reaction uses the product of light-dependent reaction which is glucose .The reaction happen in the stroma in the

Transitioning between photosynthesis and respiration : CO2 cuts into carbon and oxygen, some of the oxygen is then released and the carbon mixes with H20. If it was mad and balanced, the effect of carbon and water will also affect glucose. This is called photosynthesis. Plants take the water and CO2 in order to make food (glucose) which sets the oxygen free.

Hypothesis: If four lights (UV Light, LED Light, Infrared Light, and Blue Light) are used to perform photosynthesis on a spinach leaf, then the spinach will respond most to the blue light and perform a more efficient photosynthetic process.

The stomata are the most critical piece to this process, as this is where CO2 enters and can be stored, and where water and O2 exit. Cellular respiration also known as oxidative metabolism is important to convert biochemical energy from nutrients in the cells of living organisms to useful energy known as adenosine triphosphate (ATP). Without cellular respiration living organisms would not be able to sustain life. This process is done by cells exchanging gases within its surroundings to create adenosine triphosphate commonly known as ADT, which is used by the cells as a source of energy. This process is done through numerous reactions; an example is metabolic pathway.

The glucose will be used in cellular respiration for energy and some of the oxygen will exit the plant through the stomata to provide the world with air to breath (Simms, 2017). Cellular respiration is the next step which is a light independent reaction which takes the glucose and some oxygen from photosynthesis and produces CO2 and H2O. The balance of

Therefore the green light is unable to assist in the photosynthesis process, because the majority of the solar energy in the green light is being reflected rather than absorbed by the plant. This results in the reduction of the plant's absorption of solar energy and Co2, which subsequently leads to the decreased release of oxygen, that overall impairs the light reaction within the photosynthesis process.

Purpose The goal of this experiment conducted in lab, is to separate and identify the pigments that are found in different plants. Through this experiment, we have a variety of pigments present in plants. Plants absorb light in order to carry out photosynthesis. This light is absorbed by chloroplasts in plant cells.

More photolysis reactions take place because their job is to replace electrons in the photosystems, leading to increased oxygen output. This will only continue until the reaction has approached its optimum level. There, the light intensity will no longer be the limiting

Photosynthesis is Like a Teacher Photosynthesis is a process in which plants convert energy from the sun into stored energy food, that can be used by plants, animals, and humans called glucose. The equation that represents this is 6 CO2 + 6 H2O + light > C6H12O6 + 6 O2. The energy conversion that occurs in photosynthesis is the process in which plants and other organisms absorb light energy from the sun and convert it to chemical energy in the form of carbohydrates. This energy is then stored and is called glucose. This is important because not only are many other organisms, animals, or humans able to use/consume this energy.

The Chloroplast contains green pigment called chlorophyll which absorbs light energy from the sun. That is where the first stage occurs, which is known as, the light-dependent reaction. This stage takes place in stacked thylakoids, known as the granum. The light-dependent reaction is highly dependent on light energy. The products of this stage are light, water, and carbon dioxide.

My hypothesis is that light intensity and photosynthesis rate have a positive correlation. Meaning that as light intensity increases, photosynthesis rate will increase. This is because as light intensity increase, the rate of light-dependent reactions increase since light dependent reactions use light as an energy source. When light hits the surface of the leaf, it is absorbed by chlorophyll pigments. The light dependent reaction takes place in the chloroplast, more specifically the thylakoid membrane.

Photosynthesis is the process of converting light energy to chemical energy that can be used to fuel the organism’s activities. Photosynthesis is when the organism takes in carbon dioxide and releases oxygen. When the sun goes down, the algae start to respire. Respiration is when the organism takes in oxygen and then releases carbon dioxide to create energy.

Research Question: How does the presence of light impact the rate of transpiration in plants? Aim: The aim of this experiment was to investigate how the presence of light affects the rate of transpiration in plants. Hypothesis: As light intensity increases, the rate of transpiration (water uptake) in a plant increases.

As light intensity is increased further, however, the rate of photosynthesis is eventually limited by some other factor. (Benckiser, 2013) So the rate reaches a maximum. At very high light intensity, chlorophyll may be damaged and the rate drops steeply. This source is reliable as it is a document that focuses on the limiting factors that affect photosynthesis and pertains to this experiment because according to the graph provided, a plant photosynthesises at different rates at different times of the day.

The carbon is used in the photosynthesis formula Carbon dioxide (CO2) + Water (H2O) + Energy ➡Glucose (C6H12O6) + Oxygen (O2) to create food such as glucose. Photosynthesis extracts carbon from both land and water plants. The water plants take the carbon dioxide that is found in water whereas the land plants take it from the air.
