Why is chlorophyll important for all biological life? It is necessary for photosynthesis which creates food for plants which is food for animals. 4. A. In Part I of the procedure‚ what is the name of the indicator used to identify the presence of CO2? Phenol Red 4. B. What color did the indicator turn after blowing air into the

Unit 2: Cell Biolo SCIE206-1401B-08 Photosynthesis and cellular respiration make one large cycle that sustains life on earth. Through photosynthesis the suns energy is constantly being transformed into glucose‚ which is a chemical energy. Respiration is the chemical activity that occurs in all plants and animal cells that release the energy from the glucose. Photosynthesis cannot exist with cellular respiration‚ they are completely linked together in providing the energy through

surroundings. The nutrients enable living organisms to build their bodies‚ to grow‚ to repair damaged parts of their bodies and provide the energy to carry out life processes. Nutrition is the mode of taking food by an organism and its 1 .2 PHOTOSYNTHESIS — FOOD MAKING PROCESS IN PLANTS Leaves are the food factories of plants. The synthesis of food in plants occurs in leaves. Therefore‚ all the raw materials must reach there. Water and minerals present in the soil are

to grow properly. They use light energy to change the materials - carbon dioxide and water into food substances (sugars). This process of food productions is called photosynthesis. Only in light can a green plant make food. Plants most also have clean air. Green plants take in carbon dioxide from air and use it during photosynthesis to make food. Dirty‚ smoggy air blocks sunlight that plants must have. Plants need water. Water is essential to all life on earth. No known organism can exist without

Lil Dejay C4 2/10/14 Photosynthesis: Making Energy Chloroplasts Photosynthesis is a process in which sunlight energy is used to make glucose. The site of photosynthesis is in the chloroplast – an organelle found in the leaves of green plants. The main functions of chloroplasts are to produce food (glucose) during photosynthesis‚ and to store food energy. Chloroplasts contain the pigment‚ chlorophyll. Chlorophyll absorbs most of the colors in the color spectrum‚ and reflects only green and yellow

Associate Program Material – Heather Earnhardt Cell Energy Worksheet Answer the following questions: Cellular respiration: What is cellular respiration and what are its three stages? Cellular respiration is the process by which electrons are transferred between glucose to coenzymes and then to oxygen. NTP is made by the relocation of electrons. The end result of the process is the carbon dioxide and water that are released as byproducts of the process. The three

Maldonado Abstract: In this lab the students did two labs in which they learned the process of photosynthesis‚ which involves the use of light energy to convert carbon dioxide and water into sugar‚ oxygen‚ and other organic compounds. Oxygen is released as a product. This process is often summarized by the following reaction: 6CO2 + 12H2O ------> C6H12O6 + 6H2O + 6O2 The energy of photosynthesis comes from absorbed photons found in light and involves a reducing agent‚ in this case water. The

A. Converting photosynthesis rate from volume of oxygen produced per gram leaf per minute to mol CO2 fixed per area of leaf (in m2) per second. B. Why would one want to express photosynthesis rate as µmol CO2 m-2 s-1? What is the advantage. Answers: A. How to convert photosynthesis rate from volume of oxygen produced per gram leaf per minute to mol CO2 fixed per area of leaf (in m2) per second. Photosynthesis rate can be measured either by seeing how much oxygen is produced by a leaf

Cellular respiration is the aerobic harvesting of energy from food molecules. The first stage of cellular respiration is Glycolysis. The second stage of cellular respiration is the citric acid cycle. Lastly‚ the third stage of cellular respiration is the electron transport. • What is the role of glycolysis? Include

respiration. The main role is to transport electrons formed from NADH to oxygen in order to release the energy cells use to make ATP. Photosynthesis: What is the overall goal of photosynthesis? The overall goal of photosynthesis is to convert light energy from the sun into a chemical energy of sugar and other organic molecules. For example‚ apple trees use photosynthesis to produce both oxygen and fruit. Animal life needs oxygen
