Effect Of Light Intensity On Photosynthesis

1022 Words5 Pages

Aim To observe the effect of light intensity on the rate of photosynthesis. Hypothesis Light intensity is directly proportional to the rate of photosynthesis. When the light isn’t intense, not many oxygen bubbles will be produced and thus observed. This indicates that the plant will not have enough derived energy from the sun to activate photosynthesis. Whereas, when the light intensity is great, the rate of photosynthesis will be high. Introduction Photosynthesis is the process of converting energy from sunlight to chemical energy known as ATP which is necessary for all living organisms. The photosynthetic process uses raw materials such as water and carbon dioxide and releases oxygen and sugar as a byproduct (Mader, S. 2010). The chemical equation is: …show more content…

Chloroplasts are organelles that carry on photosynthesis; carbon dioxide diffuses into the chloroplasts in the leaves (Mader, S. 2010). Sugar and oxygen are released during the process. In order to photosynthesize, plants depend on light energy from the sun. The rate of photosynthesis will increase or decrease depending on the colour of light being absorbed, blue light results in the most photosynthesis occur and green light results in no photosynthesis occurring. Oxygen is released during the day and taken in at night through the stomata, which are small openings on the surface of the leaf. Oxygen is used to measure the rate of photosynthesis. The aim of this experiment is to observe the effect of light intensity on the rate of photosynthesis by seeing how many bubbles are

These findings show that the null hypothesis is rejected, and that there is a major difference between the observed and expected values. It is also observed that in the data in Figure 1.1, as the concentration of the NaHCO3 increases, the greater the production of oxygen. The highest photosynthetic rate is in at a 1.0% concentration of NaHCO3and the lowest in at a 0.1% concentration of NaHCO3. It is also important to note that the 0.4% concentration of NaHCO3 had a greater oxygen production than the 0.6% concentration of NaHCO3.

Transcript of 02.06 Introduction to Photosynthesis Light-Dependent Reaction : The energy releasing, light-dependent reactions of photosynthesis turn light energy into chemical energy. Which transfers this energy to ATP and NADPH, this then happens in the stacks of thylakoids of chloroplasts. ATP and NADPH are needed for the energy that is used in the light-dependent reaction.

The most important result from this experiment is that it suggested that the increase of Carbon Dioxide, will drastically increase the growth mountain maple in the covered (from the sun) parts in a forest, in the meantime any increase in the temperature of the soil will nullify the increase of light, as we know is to be the main ingredient for photosynthesis. 5.

Photosynthesis takes place in the chloroplasts; green organelles inside plant cells. The thylakoid inside Chloroplasts absorb the sunlight energy needed for photosynthesis. The pigment in the thylakoid absorbs light; however, plants reflect green light. This gives plants their color. If different colors of light are shown on spinach leaves and CO2 consumption is measured, then the spinach leaves given green light will consume the least amount of CO2 due to reduced photosynthesis activity.

Especially since the experiment states that it was a healthy plant, whereas a yellowish, drooping malnourished plant would not be able to provide sufficient data. So for the time being it'll take in CO2 until it stops functioning without the sun. Tube C would also be yellow because there is no longer equilibrium once the plant runs out of initial energy from it's previous lit environment(before being used for the experiment). Tube D will not change because there is nothing with get the blue

The objective of this study was to test the phototactic response of Daphnia when exposed to red (>600 nm) and white light. A 30 x 2 cm clear acrylic mesocosms with a 10 cm counting area was filled with distilled water and 10 Daphnia. We counted the number of Daphnia that traveled to the lit counting area after 10 minutes. There were twice as many Daphnia in the lit counting area for the control (white light) compared to the experimental group (red light). The results showed that red light had a negative effect on the phototaxis of Daphnia.

The purpose of this lab was to test the rate of photosynthesis in cut-out circles of spinach leaves in a solution with only water and a solution with water and carbon dioxide. The hypothesis made for this experiment was that the circles of spinach leaf that were placed in the solution with the carbon dioxide would float to the top more quickly than the circles of spinach leaf that were placed in just water. To test this hypothesis, twenty circles were cut with a hole punch from a spinach leaf in order to have a plant to perform the photosynthesis. Considering plants have oxygen running through their veins, the oxygen had to be taken out of the spinach circles before completing the experiment. To do that, the spinach circles were put into a syringe along with 5 mL of the solution in which they were going to be submerged.

The process of photosynthesis is vital for the survival of most life on Earth. Without photosynthesis plant life would be unable to create its own food and sustain themselves causing them to die. Earth would lack the oxygen and energy that plant life provides. Producers are the main source of energy for living organisms because they can directly absorb light energy and turn it into chemical energy. Animals then eat the plants which give them a portion of that energy.

photosynthesis and cellular respiration are extremely important in the cycle of energy to sustain life simply because nutrients would not metabolize in a productive manner. Both have numerous stages in which the process of energy occurs, and relationships with organelles located in the eukaryotic cell. Photosynthesis is a process by which green plant and other organism manufacture their food using sunlight to synthesize foods from carbon dioxide and water while cellular respiration is the oxidation of organic compounds that occurs within cells, producing energy for cellular processes. Photosynthesis occurs within organelles called chloroplasts. These organelles can absorb light, and are located inside of leaves.

Question: Do different species of hydrophytes experience different rates of photosynthesis when exposed to high light intensity over a variety photoperiods. Hypothesis: I predict that when the three species of hydrophytes are exposed to high light intensity over different photoperiods ,the hydrophytes with larger leaves will react sooner than the hydrophytes with smaller leaves and when each hydrophyte is exposed to a longer photoperiod the hydrophytes rate of photosynthesis will decline due to the high concentration of heat . Aim: This experiment is to test the effects of light intensity on the rate of photosynthesis in three species hydrophytes when each hydrophytes is exposed to the same series of lengthened photoperiods Introduction:

Effect Of Light Intensity On The Rate Of Transpiration

Background Information: In this experiment I will be investigating the impact of light intensity on the rate of water uptake, due to transpiration, by attaching a shoot from a leafy plant in the capillary tube of a potometer, and then measuring how long it takes for a bubble to move a set distance. The faster the bubble moves, the greater the rate of transpiration. I will be placing one plant in an environment where it is exposed to high-light intensities, and another plant in an environment where it is exposed to low-light intensities. Transpiration is the process of the transport of water and nutrients up the the plant from the roots to the leaves.
