Introduction Photosynthesis is a process by which plants use the sunlight to convert it from light energy into chemical energy. This equation shows us how it is done‚ 6CO2 + 6H2O + light energy --> C6H12O6 + 6O2. The pigments called chlorophylls in the plants are what trap the light energy. Carotenoids also help aid the chlorophylls by also absorbing light. The two chlorophylls found in green plants are chlorophyll a and chlorophyll b. The purpose of this lab is to extract the pigments from spinach leaves

called Photosynthesis. The food that they produce is the sugar glucose. Animals and other organisms are heterotrophs (other- feeders). They must consume other organisms (plants) in order to eventually get their glucose. Both plants and animals use glucose as an input to the process of Cellular Respiration (another subject) to produce ATP molecules. ATP molecules are the energy source for all metabolic processes. Log on to the following web site for a good explanation of photosynthesis. Pay attention

Which of the following energy-generating processes is the only one that occurs in all living organisms:

anabolic reaction is photosynthesis where small molecules are built up into larger ones using energy. ATP is built up from ADP and inorganic phosphate ions (3-4 PO‚ abbreviated to Pi) by condensation and is then hydrolysed by the enzyme ATPase to ADP and Pi to release energy that can be used for energy requiring reactions such as photosynthesis in plants. Plants are able to produce ATP during the light dependent reaction of photosynthesis in the thylakoid of the chloroplast. Red and blue wavelengths

Research question : How does the different light intensity affect the rate of photosynthesis in plants? Objective : To investigate the relationship between different light intensity (by having the source of light at different distance to the plant discs which is at; 10cm‚ 15cm‚ 20cm‚ 25cm‚ 30cm‚ and 35cm ) and rate of photosynthesis of plant. Introduction : Photosynthesis is the process where light energy is absorbed by green plants to convert the raw materials (carbon dioxide and water) into

Plastids such as chloroplasts that contain chlorophyll‚ the pigment that gives plants their green color and allows them to perform photosynthesis.

have small kitchen gardens where you both grow tomatoes. His blotchy green and red tomatoes taste much sweeter than your perfectly uniform red ones. Could the sweetness of the tomatoes be effected by the green chloroplasts in the fruit? Hypothesis I personally think that the green chloroplasts do play a part in the sweetness of the tomatoes because it doesn’t state how ripe the tomatoes were when they were eaten‚ what type of soil was used to plant them and if the same type of tomato seeds were used
