Courtney S. 4th Period SINKERS and FLOATERS Purpose:The purpose of this investigation is to provide an overview of photosynthesis and to design and conduct an experiment to test the factors that affect the rate of photosynthesis. Hypothesis:If 10 leaf discs are placed into 2 plungers and placed under a lamp the CO2 rate will speed up the process of photosynthesis. Materials: -Fluorescent lamp - Hole punch - 1 Sharpie marker -20 leaf discs -Syringes -12 mL cups Data Table Start 2 4 6 8

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

Autumn Leaves Trees have green leaves due to the abundance of chlorophyll and chloroplasts in leaves. These organelles absorb‚ store and convert light energy from the sun and is necessary photosynthesis to occur. These organelles reflect green light which attributes to the green color of leaves. The leaves change color in the fall and winter do to the shortened times of daylight and lower temperatures. Trees also divert nutrients from leaves to store in twigs and branches for preparation of winter

Dennis Carrasco 11-20-12 Introduction For this project we had to experiment to see the effects of blue light on a plants growth. We had to research on light and its effects on photosynthesis. This helped me with my experiment because I had knowledge for what was going on with the plants and light. For this project I and one of my classmates had to conduct a experiment to see the effects of blue light versus white light. For this project we had to grow lentil beans under white and blue light and

changing the concentration of carbon dioxide affect the rate photosynthesis in plants? Introduction: Photosynthesis is the process through which plants‚ algae‚ and some bacteria convert light energy into chemical energy from carbon dioxide and water‚ producing glucose and oxygen. This process is extremely vital as it the major source of nutrition for all living things on Earth‚ and fuel organisms’ activities. The equation of photosynthesis is as follows: 6CO2 + 6H2O C6H12O6 + 6O2 Background:
