Name_______________________Period___________ Chapter 9: Cellular Respiration: Harvesting Chemical Energy Overview: Before getting involved with the details of cellular respiration and photosynthesis‚ take a second to look at the big picture. Photosynthesis and cellular respiration are key ecological concepts involved with energy flow. Use Figure 9.2 to label the missing parts below. See page 163 of your text for labeled figure. Concept 9.1 Catabolic pathways yield energy by oxidizing organic

Relevant to: 2.5.2. Describe photosynthesis in terms of inputs‚ outputs and energy transformations. Criteria to be assessed: PL‚ DCP‚ DEC. Background: Photosynthesis is the reaction carried out by green plants to produce a supply of food. The reactions occur in the chloroplasts and require light energy. 6CO2 + 6H2O C6H12O6 + 6O2 In aquatic plants‚ the production of oxygen can be used to measure the rate of photosynthesis as the oxygen bubbles can

no growth. 2. How does increasing light intensity affect the rate of photosynthesis? Light intensity is a factor which can limit the rate of photosynthesis because if the light intensity is increased the rate of photosynthesis increases. However‚ at higher light intensities‚ the rate of photosynthesis will level off. 3. Describe the process of photorespiration. What is its effect on the rate of photosynthesis? Photorespiration is the process of combining PGA and glycolate to make

oxygen from the lungs to the cells in the body‚ allowing the cells to perform cellular respiration. The roots intake specific compounds from the soil‚ which are carried through the xylem to the leaves. There‚ they are used in the process of photosynthesis to create glucose as a source of energy. The glucose is carried throughout the plant through the phloem. Food/Energy Processing Food (meat‚ plants‚ etc) is eaten by the animal organisms‚ which chew the food to allow it to go through the esophagus

(Ch. 12‚ Section “How Are Marine Organisms Classified?”) Plankton Plankton is a organism that float. Why is a copepod‚ which can swim and propel itself through the water‚ classified as plankton? (Ch. 12‚ Section “Plankton”) Because of its small size‚ it cannot swim very far or fast so its location

growth. For those interested in harvesting duckweed‚ future studies can focus in determining the amount of light needed for optimal growth. Introduction Plants are able to convert light energy into chemical energy through the process of photosynthesis (Campbell & Reese‚ 2005). This process is dependent on both abiotic and biotic factors. Since plants are autotrophs‚ the most vital are abiotic factors such as light‚ temperature‚ wind‚ water‚ and atmospheric gases (Campbell & Reese‚ 2005). The

Chloroplasts are the most important plastids found in plant cells. It is the structure in a green plant cell in which photosynthesis occurs. Chloroplast is one of the three types of plastids. The chloroplasts take part in the process of photosynthesis and it is of great biological importance. Animal cells do not have chloroplasts. All green plant take part in the process of photosynthesis which converts energy into sugars and the byproduct of the process is oxygen that all animals breathe. This process

the Cell wall are only found in Plant cells. The Chloroplast is the organelle for the whole system of Photosynthesis. Chloroplasts are found in mesophyll cells (which are found in the leaves) of green plants. They convert light into energy; therefore the energy is the plant’s food. The chemical in Chloroplast is called ‘Chlorophyll’; this is the chemical that generates the process of photosynthesis. Vacuoles are found in Animal cells as well‚ but they are particularly smaller than and not as big
