Answers to Photosynthesis Practice AP Biology 1. Draw a picture of the chloroplast and label the stroma‚ thylakoid‚ thylakoid lumen (space)‚ inner membrane‚ outer membrane. 2. Using 18O as the basis of your discussion‚ explain how we know that the oxygen released in photosynthesis comes from water. When the oxygen in water has the radioactively labeled oxygen‚ the gas released from photosynthesis also has the labeled oxygen. This shows that the oxygen gas given off during photosynthesis comes from

Energy In A Cell – Respiration & Photosynthesis Cellular respiration and photosynthesis are complementary reactions. In this lab‚ you will review both processes and put the steps of each in order of occurrence. You will gain from this exercise an overall understand of how these processes work hand-in-hand in cellular organisms. You will go to the following website: http://glencoe.mcgraw-hill.com/sites/dl/free/0078757134/383932/BL_25.html After reading the guide‚ you will work to move

Title: Rate of Photosynthesis Introduction: Photosynthesis occurs in plants where the light energy changes to chemical energy. This process occurs in the chloroplast of the plant cell in order to have gas exchange in the organism. Purpose: To measure the effect of light intensity on the rate of photosynthesis in the leaf cells. Hypothesis: The higher the concentration of the sodium bicarbonate solution‚ the faster the leaf of the plant will rise to the surface of the water in the beaker‚ the

WHAT IS PHOTOSYNTHESIS? 3 Every day the total amount of energy that is captured through photosynthesis all across our planet is equal to approximately 135 terawatts. Now to put this number into perspective the entire human race consumes approximately 15 terawatts of energy daily. This means that there is 9 times more energy being absorbed every day through photosynthesis‚ as there is energy being consumed by all of mankind (Bridges 2008). In order to fully understand photosynthesis

Photosynthesis is a chemical process that converts the sunlight into a chemical energy that plants store for later. Without photosynthesis‚ the world as we know it would not exist. All the plants would die and so would a major food and oxygen source. During Photosynthesis water is sucked up through the roots up the stem and to the leaves. The leaves take in carbon dioxide and begin to absorb sunlight. these things combine to make glucose and oxygen. The plant then uses the glucose and oxygen is

Photosynthesis is a form of a chemical reaction that transforms energy from the sun in to a chemical energy‚ a carbohydrate known as glucose. Only plants are able to use this process to make their own food. This chemical reaction takes place in Chloroplasts‚ cells that are found in any green part of the plant. Chloroplasts are in green fragments of the plants because it contains a green pigment called chlorophyll. Although Photosynthesis can occur in any green portion of a plant‚ it mostly occurs

How does the colour of light affect the growth of a plant and which light is best The problem will be investigated is how does colour of light affect the plant growth and what colour is best in terms of speed of the growth of the plant By using the internet I discovered that the problem that I am trying to solve has been done before by various people. As I read the information given off the web it seems that plants that can only absorb certain types of colour of light for example blue or red

Does Huckleberry Have A Prayer? In Mark Twain ’s Huckleberry Finn‚ the concepts of prayer‚ religion‚ and spirituality are introduced early on in the novel‚ and their influence on Huck ’s character and their role in the overall story is evident regardless of the theory of criticism that is employed for interpretation. A New Critic scours the text for conflicts‚ symbols‚ and resolutions while examining word choice in an effort to determine the literal meaning (Bressler 45-48). A Reader-Response

processes of aerobic respiration and photosynthesis. To start‚ aerobic respiration can be defined as a biochemical pathway through which chemical bond energy is released from food and changed into ATP. On the other hand‚ photosynthesis is manufacturing of carbohydrates out of CO2 and the splitting of water in the presence of light. Photosynthesis and aer. respiration can be the same in many ways. For instance‚ both of them contain cycles. In photosynthesis‚ there is the Calvin cycle‚ and photosystem
