photosynthesis in Ivy disks Background: All plants are autotrophs meaning they create their own food from inorganic chemicals in their surrounding. In the case of food‚ plants use CO2 to create glucose. In addition to the inorganic chemicals‚ plants use sunlight to create their glucose because the photosynthesis reaction is endothermic. The rate of this reaction‚ in turn‚ can be measures. And this lab uses oxygen which is created as a result of the photosynthesis reaction. Since

Determination of rate of photosynthesis INTRODUCTION Photosynthesis is the major process by which light from the sun is captured by plants‚ algae and some bacteria to produce energy. It is a process in which light energy is converted into chemical energy which is then stored in sugars. Photosynthesis occurs in two stages‚ light-dependant reactions and light-independent reactions. In light-dependent reactions the chlorophyll traps light energy which is then used to excite electrons and split water

Biology Notes: Threats to biodiversity in MA 1. Climate change: temp‚ sea levels‚ precipitation 2. Non climate threats such as habitat loss‚ habitat fragmentation‚ and invasive species and air and water pollution Fragmentation: often due to man (dams‚ roads‚ and general development) Elements of biodiversity: Species‚ ecosystems & landscapes Mammals from bats to bears Bats got the white nose fungus which caused the bats to die and the insect population flourished because the bats main job

Rubyna May L. Espiritu Sir Adrian Guinto BSEDSS 1-1N November 15‚ 2012 The Characteristics of Life There are many properties or the signs of life that the living organisms have. In the book of biology of Mrtinez and Nazareno‚ there are nine characteristics of life just said and those are : a. Living things are highly organized and contain many complex chemical substances ; b. Living things are made up of one or more cells‚ which are

highest amount rise‚ which will show us the optimal color of light for photosynthesis. These different colors of light included blue‚ red‚ green‚ fluorescent‚ regular light‚ and classroom light. The classroom light was our control cup during the lab. Before we conducted our experiment‚ the class learned about the photosynthetic process of‚ not only spinach discs‚ but plants in general. As I did more research on photosynthesis‚ the Calvin Cycle‚ wavelengths and pigments required for a proper equation

Photosynthesis depends on an interaction between two sets of reactions: the light reactions and the Calvin cycle. Chlorophyll and the other molecules responsible for the light reactions are built into the thylakoid membranes. The enzymes that catalyze the Calvin cycle are located in the stroma. Beginning with the absorption of light by chlorophyll‚ the light reactions convert light energy into chemical energy in the form of ATP and NADPH. The ATP provides the energy‚ and the NADPH supplies the electrons

Lauren Spillers Biology 1408 February 5‚ 2013 Lung Cancer Lung cancer is the number one form of deadly cancer in the United States. It is not only something that can kill you but also can put a strain on you and your family financially‚ emotionally‚ and medically. Lung cancer is formed when the cells of the lungs grow in an uncontrolled way‚ this creates a lump or a tumor which can either be malignant (cancerous) or benign (not cancerous). Radon gases‚ smoking‚ and second hand smoke cause lung

Experiments investigating the effect of a particular factor on an enzyme-catalysed reaction are commonly used as assessed practicals in Biology. The reason for this is there are a number of factors that can be investigated‚ and therefore‚ a number of factors that can also be controlled. From our lecture‚ we are aware that the following can affect the rate of reaction: 1) Temperature: a. Independent variable: A range of temperatures should be investigated‚ with particular attention

Acid Rain Done By: Francis Lolas Teacher: Christine Due Date: 19/9/2012 Grade: 10 MYP 5 A There are many possible solutions to the problem that we are facing nowadays that is Acid Rain. Acid rain is formed from two main gases that are released in the atmosphere which are sulphur oxide and nitrogen oxide. I will talk later about the solutions for acid rain and the effect of this rain and what are the two forms of acid deposition. I have also watched some videos about acid
