with what you observed for tomato plants? With both plants the photosynthesis rate increased while the light intensity increased. 2. Photosynthetic saturation is the maximum rate of photosynthesis. What value of light intensity produced photosynthetic saturation in corn leaves? 804 Lab Summary Address the following points in a 100-to 200-word summary: The purpose of this lab was to figure out the reactions of photosynthesis as the light intensity increased in tomato and corn plants.

then is used by photosynthesis of phytoplankton in the water. During the photosynthesis that takes place‚ sunlight‚ water‚ and carbon are taken in by the plankton and then a fish eats this phytoplankton and this organism dies. When the fish dies it decomposes‚ and when organisms decompose they release carbon dioxide into the air. When the carbon dioxide is in the air it is used by some spinach plants. The spinach plant uses the carbon dioxide during a process called photosynthesis.

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

because light stimulates the opening of the stomata and photosynthesis would occur. HYPOTHESIS 2: Transpiration would occur the second most when there’s light and lots of humidity. JUSTIFICATION: The light would allow photosynthesis to occur and the stomata to open but little if any diffusion of water out the leaf would occur. HYPOTHESIS 3: Plants transpire the least when it is dark and there is lots of humidity. JUSTIFICATION: Photosynthesis does not occur without light and the humidity prevents

Determining Rates of Photosynthesis Through Chloroplasts Introduction: 1)Background= 2) Purpose= measure the rate of photosynthesis in chloroplasts. 3) The chloroplast will be subjected to two experimental conditions- light‚ and the absence of light‚ using a spectrophotometer to determine the amount of DPIP reduced at specific time intervals under each condition. 4) I predict the amount of DPIP reduced will vary for each condition and increase over the time intervals. I hypothesize

Jamie Milano Biology 150 Photosynthesis Homework April 8‚ 2013 Reviewing Your Knowledge 2. A pigment solution contains compound A with 4 polar groups and compound B with 2 polar groups. You plan to separate these compounds using paper chromatography with a non-polar solvent. Predict the location of the two bands relative to the solvent front. Explain your answer. Since compound A is probably more polar than compound B‚ compound B will move further in the chromatography. Since the solvent is non-polar

Dicot roots have X-shaped xylem whereas monocots are organized into a ring 3. Dicot stem xylem form a ring around the outside whereas monocot xylems are scattered 9.1.3 Distribution of tissues in leaves and functions In the leaf you have xylem and phloem tissues. Xylem tissues act like transport tubes‚ transporting water and minerals. Phloem tissues

both the air and the rocks that the water ran off. These new water pools became ideal for the basic organisms to form and live. The first living organisms on Earth used photosynthesis to make their energy. Photosynthesis is one of the main processes that removes Carbon Dioxide from the atmosphere. The equation for photosynthesis is: Carbon Dioxide + Water = Glucose + Oxygen 6CO2 + 6H20 = C6H12O6 + 6O2 It was this that led to less Carbon Dioxide and more Oxygen in our atmosphere today. The
