Elodea, a plant and autotroph can take on photosynthesis in the light and cellular respiration snails, a heterotroph, can only have cellular respiration in light or darkness if the elodea had been in the dark, photosynthesis could not occur, yet cellular respiration could, since plants can have it and it can happen in darkness. Respiration vs photosynthesis these are the two of the most important processes of life without any of either respiration or photosynthesis, the world would be a miserable place without life. Properties of light in the first part of the lab, students learn how to measure the rate of photosynthesis differences affect photosynthesis the lab also. Photosynthesis is the process by which plants, algae, some bacteria, and other organisms convert light energy and carbon dioxide into oxygen and glucose it is an essential part of the life cycle, and the reason that plants are at the bottom of the food chain.
Experiment to demonstrate moll's half-leaf experiment for showing that co 2, light, chlorophyll and water are necessary requirements for photosynthesis: requirements: a potted plant, caustic potash, wide- mouthed bottle, iodine, split cork, water. Sample essay question from ap exam: describe the similarities and differences between the biochemical pathways of aerobic respiration and photosynthesis in eukaryotic cells include in your discussion the major reactions, the end products and energy transfers. Earth is the light that comes from the sun (see the box on the next page for an example of organisms that do not depend on light as the ultimate source of energy ) photosynthesis and cellular respiration are two of the most important biochemical processes of.
Show more show less the light dependent reactions of photosynthesis - duration: photosynthesis and cellular respiration lab - duration: 5:45 ayesha khan 29,190 views. Difference between respiration and photosynthesis in aerobic and anaerobic respiration , glycosis vs krebs cycle , respiration and photosynthesis , respiration vs photosynthesis respiration is a complex process which includes absorption of oxygen, conversion of complex substance to carbon dioxide and water, relea. Although photosynthesis occurred at all distances from the light source, the amount of bubbles decreased as we increased the distance from the light source intro cellular respiration and photosynthesis are processes necessary for life organisms, they help to sustain life. This lab gave a correct representation of the processes of cellular respiration and photosynthesis by showing the changes of fluid position of the food coloring, this let me to see the changes that cellular respiration actually does. 2 you will note that one of the products of photosynthesis is oxygenessentially most of the oxygen in our atmosphere comes from the process of photosynthesis like photosynthesis, cellular respiration is also a series of chemical reactions.
The nature of light a common aquarium plant used in lab experiments about photosynthesis images from we can see anatomical differences between c3 and c4. Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that can later be released to fuel the organisms' activities (energy transformation. Hence in photosynthesis you have the light dependent reactions and the dark reactions while in respiration there is aerobic respiration and anaerobic respiration in photosynthesis light dependent reactions, ultra violet light strikes chlorophyll pigments which excites electrons leading to separation of oxygen molecules from carbon dioxide. Understand the relationship between stomata and photosynthesis and respiration 4 be able to explain the relationship between light intensity and photosynthesis.
Photosynthesis-respiration lab introduction: in this activity, you will perform two experiments that demonstrate the use and production of carbon dioxide (co 2) during photosynthesis and cellular respiration. There are many differences between the non-cyclic reactions of photosynthesis and the electron transport chain of cellular respiration open document click the button above to view the complete essay, speech, term paper, or research paper. 1 photosynthesis gas exchange and carbon exchange rates in this demonstration you will study the rate at which light affects co2 exchange between plants and the atmosphere. Your lab group is asked to design, execute, and analyze an experiment that tries to accomplish the following two tasks: task a demonstrate that environmental co2 is used during photosynthesis in elodea.
Learn how photosynthesis and respiration are connected to each other. Why do we use it- gives an indication of the rate of the light reactions of photosynthesis under various conditions what roll does it play- an electron acceptor when light strikes the chloroplasts, the dpip is reduced by the excited electrons from chlorophyll, and it changes from its original blue color to colorless as it accepts the electrons.
Analysis: to make comparisons between experiments, a standard point of reference is needed repeated testing of this procedure has shown that the point at which 50% of the disks are floating (et50) is a reliable and repeatable point of reference. We will show the effects, reactions, and relationship between photosynthesis and respiration, as well as demonstrate to you how the scientific method works hypothesis upon completion of the investigation we will be able to determine if gas that will be produced with the intensity of light at different wattages. This activity will allow students to measure the rate at which the photosynthesis process occurs students will work in small groups to design an experiment with one independent variable and test this variable on spinach leaf disks.
