Compare and contrast photosynthesis and cellular respiration. A Comparison of Photosynthesis and Cellular Respiration: How are They Connected? How are They Different? 2019-01-05

Comparing Photosynthesis and Cellular Respiration by Faith Reyes on Prezi

There is a variety of different cells, each of which perform a variety of functions necessary for the life of living things. Photosynthesis involves a set of chemical reactions, where Carbon dioxide and water are converted and released as glucose and oxygen to the atmosphere with the help of light energy. Reaction takes places in presence of chlorophyll. Cellular respiration cannot occur without photosynthesis, and photosynthesis certainly cannot occur without the help of its partner. Photosynthesis is a very crucial process which allows life to continue on earth.

Occurs in plants, protista algae , and some bacteria. Try out the Plant Pigment Lab at Pearson's LabBench to witness this in action: Poetic Justice Here's an opportunity to get your creative talents soaring, or at least skipping. That waste carbon dioxide gets taken up by plants and ends up in the chloroplast. An Object that absorbs all colors appears black. Increasing the intensity of light decreases the rate of photosynthesis. Oxygen goes into the lungs, and carbon dioxide and water leave the lungs.

While all animals use respiration, plants use both photosynthesis and respiration. Understanding the Photosynthesis Process Photosynthesis, a chemical process, is part of a larger process known as. Respiration and Photosynthesis Metabolism includes both the breakdown of molecules to obtain energy and the use of energy to build molecules. During photosynthesis,carbon dioxide, water, and light energy is turned into glucose andoxygen. In respiration, electrons are transferred from glucose molecules to oxygen. However, the direction of electron movement is opposite in the electron transfer chain.

Biology

Objects or organisms vary in color because of their specific combination of pigments. Explain how photosynthesis and respiration are linked in order to provide you with energy from the food you eat. This takes place in the plant cells that contain chlorophyll, the pigment within plant leaves that give them their green color. The chloroplast is made of grana, thylakoid, and stroma. Oxygen is released in to the atmosphere as a byproduct of the process and it is essential for the process of respiration of most living creatures. Harvesting Energy Interactive Visit the interactive resource called Harvesting Energy. All living organisms carry out both parts of metabolism but here we are just focusing on two different kinds of metabolism: respiration and photosynthesis.

Compare Photosynthesis and Cellular Respiration Essay

If oxygen is not present the respiration would happen by two metabolic pathways in the cytosol glycolysis and fermentation. Producing Energy All living organisms must find a way to harvest energy in order to maintain life. Have your handout ready so you can stop the video as needed to answer questions. How is each linked to specific organelles within the eukaryotic cell? Throughout various steps in glycolysis and the Krebs cycle electrons are transported along a specific chain of molecules, known as the electron transport chain. Cellular respiration uses glucose and oxygen to produce carbon dioxide and water. Use this rubric to assess your work before submitting it.

Comparing & Contrasting Cellular Respiration & Photosynthesis

While the process of cellular respiration can occur regardless of the time, some parts of photosynthesis can only occur in daylight Conclusion In conclusion, we can summarize that both photosynthesis and cellular respiration are processes, which organisms use to obtain energy. Photosynthesis mainly transpires in plant leaves. The plants physiology will slow down when the temperature dips below zero degrees Celsius, resulting in photosynthesis stopping. The difference in the 2 molecules is the way they store energy. And, there are microorganisms that are capable of both processes! Enough energy is passed from Autotroph to Heterotroph to give the Heterotroph the energy it needs. Students will derive the relationship between single-celled and multi-celled organisms and the increasing complexity of systems.

Watch the video Powerhouse of the Cell at Teacher's Domain. Image source Heterotrophs as well as autotrophs utilize cellular respiration to supply the energy to power cellular activities. We usually think about respiration happening in animals and photosynthesis happening in plants but really it isn't that simple. The distance of the movement can be quite large moving a rocket from the face of the earth to the moon or beyond. Light and Pigments 12 What does photosynthesis require in addition to water and carbon dioxide? The plants need what the animals let out and the animals need what the plants let out. The light reaction comes about in the thylakoid membrane and then switches light energy to chemical energy.

Formation of acetyl CoA 3. The Krebs cycle-that occurs in mitochondrial matrix. Chloroplast contains chlorophylls in plants and in bacteria. Glucose is most commonly used to explain cellular respiration. Sunlight in the form of light energy is used to fuel the photophosphorylation process where 2 water molecules break down into 4 H+ ions, 1 oxygen molecule, and 4 electrons.

Another process called chemiosmosis also occurs in the light reaction. Another difference is that the byproducts of cellular respiration are always water and carbon dioxide. In photosynthesis light dependent reactions, ultra violet light strikes chlorophyll pigments which excites electrons leading to separation of oxygen molecules from carbon dioxide. Investigate carbon dioxide production in both germinating pea seeds and crickets. There are also plants that change their colors seasonally because of environmental triggers.
