Write the equation for photosynthesis: Photosynthesis occurs in the chloroplast‚ an organelle in plant cells that contains the molecule chlorophyll

materials both plants and animals take in to grow and prosper. 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. 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

rate of growth in Brassica rapa. Hypothesis If the plant that is exposed to high intensity light grows more‚ then plants can adapt to absorb more photons for photosynthesis. Eventually‚ the rate of photosynthesis will top out‚ and stop increasing‚ due to the lack of one of the components necessary for photosynthesis. Background: Photosynthesis is a process used primarily by plants but sometimes by other organisms to convert light energy into chemical energy that can later be released. This chemical

producer plant. The alternative hypothesis was that the rate of photosynthesis increases as the distance of the light decreases. This is because light energy can excites chlorophyll molecules more clorophyll mulcoulse as the distance of the light decreases. Photosynthesis is a process in which the energy of light is used to produce organic molecules. In this process Oxygen is released; therefore the rate of photosynthesis can be calculated by measuring the rate of oxygen production

have a starch level of 1 because the plant is missing CO2‚ which it needs to complete the photosynthesis process. 2. If the plant is in a closed environment‚ then the plant will have a starch level of 3 because it has all the environmental conditions it needs. 3. If the plant is kept in a dark environment‚ then it will have a starch level of 1 because it’s missing a fundamental resource needed for photosynthesis. 4. If the plant is kept in the presence of light‚air‚soil‚and water‚ then the plant will

Irradiance limits the overall rate of photosynthesis under low light conditions. As irradiance increases‚ photosynthesis begins. C4 plants generally exhibit higher rates of photosynthesis when compared with C3 plants because of the fact that although photorespiration rates increase with increasing

Racquel Currie University of Minnesota Minneapolis‚ Minnesota Hypothesis If isolated chloroplasts are boiled‚ the enzymes that occur in photosynthesis are disrupted and the DCIP will not reduce. Chloroplasts are a type of plastid found within the plant they are the basis of photosynthesis. Without photosynthesis there would be no life on earth. Photosynthesis takes the energy from sunlight and coverts it into a chemical energy that can be used by the plant. Isolating chloroplast is a way to

Associate Program Material Cell Energy Worksheet Answer the following questions: Cellular respiration: • What is cellular respiration and what are its three stages? A living version of internal combustion-is the main way that chemical energy is harvested from food and converted to ATP energy‚ it is also called an aerobic process‚ which is just another way of saying that it requires oxygen. So cellular respiration is defined as the aerobic harvesting of chemical energy

and chlorophyll. This process of plants making their own food with sunlight and chlorophyll is called photosynthesis. The photosynthesis process involves sunlight‚ sugar‚ and chlorophyll. Chlorophyll is called a photoreceptor. It is found in the chloroplasts of a plant cell that is within green plants‚ and is what gives green plants their green color. Chlorophyll has a special role in photosynthesis. Chlorophyll molecules absorb light energy. Chlorophyll is a complex molecule‚ which has lead to a
