PLANNING Research Question: How does the change in temperature levels affect the amount of oxygen released? Hypothesis: The rate of photosynthesis will be slow in extreme temperatures (either too hot or too cold). Hypothesis Explanation: The change in temperature levels during the process of photosynthesis will affect the amount of oxygen released. The rate of photosynthesis can be inferred by measuring the amount of oxygen released. Therefore if in extreme temperature like too hot or too cold the
intensities on photosynthesis in plants BACKGROUND INFORMATION: Aquatic plants can be used to demonstrate oxygen evolution in the process of photosynthesis. In theory, when an aquatic plant is placed in a solution containing a source of carbon dioxide (CO2), in the presence of light of appropriate intensity, the plant will photosynthesise and produce bubbles of oxygen-containing gas. These bubbles can be counted and the rate of bubbling can serve as an indication of the rate of photosynthesis. When the
Nicole Fedder Biology 105 Sect 01 Photosynthesis Paper Rate of Photosynthesis Using Floating Leaf Disks Introduction Photosynthesis is an important process for all life on Earth. The process is used by plants and other organisms to convert light energy captured from the sun into chemical energy that is released as oxygen which can be provided to help fuel other organisms. Plants use this process to convert carbon dioxide gas that humans can’t breathe and break it down into oxygen. This oxygen is
ESS PLANNING LAB 3 Research Question: How does light intensity affect the rate of photosynthesis of green spinach leaves? Background: Spinach leaf disc normally float but the spinach discs will be filled with fluid by using a syringe (explained in method), once they are filled it affects the buoyancy of the spinach disc causing them to sink. Photosynthesis uses light energy to convert carbon dioxide and water into glucose and oxygen. When photosynthesis occurs in the leaf disc oxygen will be
Eutrophication is an environmental process that affects the chemical and biological properties of the water ecosystem. This topic was chosen as the investigation of this EEI, due of its harmful effects on the water’s ecosystem. Eutrophication The topic Eutrophication is defined by Schindler, 2006 “Eutrophication is characterized by excessive plant and algal growth due to the increased availability of one or more limiting growth factors needed for photosynthesis”. This process can either occur naturally
Investigation 1: Respiration of Peas Introduction: There are 3 main methods through which we are able to monitor/ measure the rate of cell respiration. These 3 include; measuring the amount of glucose consumed, measuring the amount of oxygen consumed and measuring the amount of carbon dioxide consumed. In this investigation i will focus on an experiment with the experimental method of measuring the amount of oxygen consumed. When wanting to measure the amount of oxygen consumed we use a tool
air conditioner for the surface because heat is used when water enters the atmosphere as moisture. Higher temperature mean there is more evaporation from land and sea into the atmosphere. As the air gets
1. What are mean flows? How are these flows controlled in tropical vs. temperate systems? Explain critical abiotic and biotic factors in tropical systems using energy circuit language. Mean flows can be described as the net energy, carbon, nitrogen, and phosphorus that move through an ecosystem. This incorporates many biotic and abiotic factors, which affect the speed and amount of energy or nutrients through the ecosystem. Looking at the Odum model of energy circuit (Mann 11) clearly shows the

the average weather in a place. It includes patterns of temperature, precipitation (rain or snow), humidity, wind and seasons. Climate change is a change in the statistical properties of the climate change system that persist for several decades or longer-usually at least 30 years. The statistical properties include averages, variability and extremes. Climate change, also called global warming, refers to the rise in average surface temperatures on Earth. Climate change may be due to natural processes
