energy. 9. Explain how C4 photosynthesis is based on a spatial arrangement of structures‚ whereas CAM photosynthesis is temporally based. C4 photosynthesis is based on a spatial arrangement of structures because in C4 plants‚ light and carbon reactions are separated into different cells. The light reactions along with a carbon-fixation reaction occur in mesophyll cells‚ but the Calvin cycle occurs in the inner ring of bundle-sheath cells. However‚ CAM photosynthesis is temporally based because

the ultimate source of energy for life? Plants undergo the process of photosynthesis‚ where they absorb light energy and convert it into sugar. This process expels oxygen‚ which all living things require to survive. In addition‚ plants are a food‚ and hence an energy source‚ for many living creatures‚ making them essential in the food chain. 3. Describe the purpose‚ process‚ and chemical and energy components of photosynthesis and the source of each component (e.g. CO2 is found in the air)? Chloroplast

However‚ as I will elaborate later‚ carbon dioxide also has adverse effects on organisms. Carbon dioxide primarily affects all organisms as it is essential for the process of photosynthesis‚ in which organic compounds vital to a plant’s growth ‚ and essential as food for a primary consumer ‚ are synthesized. In photosynthesis carbon dioxide diffuses through the stomata on the underside of a plant‚ into the mesophyll layer of the leaf and finally into the photosynthesizing cells of a plant. In these

Dissolved oxygen enters water through the air and plant. Dissolved oxygen produce by the atmosphere and the process is called air saturation. The gasses a stable body of water with no stratification‚ dissolved oxygen will remain at 100% air saturation. 100% air saturation means that the water is holding as many dissolved gas molecules as it can in equilibrium. At equilibrium‚ the percentage of each gas in the water would be equivalent to the percentage of that gas in the atmosphere like its partial

1. Explain how photosynthesis and respiration are linked in order to provide you with energy from the food you eat. To start off with we will need to define photosynthesis and respiration. Photosynthesis is a process in which carbon dioxide‚ water‚ and certain inorganic salts are converted into carbohydrates by green plants‚ algae and certain bacteria using energy from the sun and chlorophyll (dictionary.com). Respiration is all of the physical and chemical processes in an organism by which oxygen

The Calvin Cycle Plants use energy from the sun in tiny energy factories called chloroplasts. Using chlorophyll in the process of photosynthesis‚ they convert the sun’s energy into storable form in ordered sugar molecules such as glucose. In this way‚ carbon dioxide from the air and water from the soil in a more disordered state are combined to form the more ordered sugar molecules. Carbon dioxide is captured in a cycle of reactions known as the Calvin cycle or the Calvin-Benson cycle after
