Photosynthesis is the process of converting light energy to chemical energy and storing it in the bonds of sugar. This process occurs in plants and some algae (Kingdom Protista). Plants need only light energy‚ CO2‚ and H2O to make sugar. The process of photosynthesis takes place in the chloroplasts‚ specifically using chlorophyll‚ the green pigment involved in photosynthesis. Photosynthesis takes place primarily in plant leaves‚ and little to none occurs in stems‚ etc. The parts of a typical leaf

levels affect photosynthesis rate Phaladi Phaladi 201102379 Department Of Mathematics And Science Education University Of Botswana Plants‚ through the use of chlorophyll (green pigment in plants) that traps light can generate ‘food’ by combining carbon dioxide in the air and water. As with many chemical process energy is need to make and break molecules during the chemical process. The greater the light levels the more energy is available to carry out process of photosynthesis. Some photosynthesis

Title: Effects of Light on Photosynthesis Introduction: Photosynthesis is the complex process by which carbon dioxide and water are used to make carbohydrates by using light energy in green plants. The objective of this experiment is to measure the rate of photosynthesis Hypothesis: The petri dish that is exposed to the most light and with the NaHCO3 solution will have the best results and the petri dish that is kept in the dark will have the poorest results.

Chlorine in Photosynthesis Experiment Abstract Photosynthesis the means by which green plants and different types of organisms use light from the sun to synthesize foods from CO2 and H2O. Chlorine is a chemical element usually in the form of a yellow-green gas and is a strong oxidizing agent. Elodea is a type of aquatic plant also known as waterweed that is native to North America. In the experiment that took place‚ the effect of chlorine in the presence of photosynthesis reactions were studied

There are many variables that could affect the rate of photosynthesis and the net consumption of carbon dioxide. In this experiment‚ the effects of how the intensity of light energy affected photosynthesis were observed. Two pieces of elodea was placed into separate beakers and one of the beakers was placed under a bulb of lower intensity and the other beaker being placed under a higher intensity bulb. The results showed that the beaker under the higher intensity light energy had a higher consumption

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

AFFECTING THE RATE OF PHOTOSYNTHESIS. Introduction Photosynthesis is a chemical reaction which takes place inside the green plants (plants with chlorophyll‚ a pigment found in chloroplasts which causes the colour of the plants and it is the main photosynthetic pigment) and light energy is converted into chemical energy. Carbon dioxide‚ water and sunlight is transformed into sugar an oxygen‚ which later will be used as energy for the plant. The chemical equation of photosynthesis is: Photosynthesis

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

The color we see comes from the wavelengths of light that reflect. Chlorophyll‚ the green pigment common to all photosynthetic cells‚ absorbs all wavelengths of visible light except green. The green reflects back to our eyes
