Furthermore, I hypothesise that if the light intensity increases, the rate of photosynthesis will increase at a proportional rate. There are two reasons of this. Justify why you agree or disagree. It may be stated that direct effect of O 2 on photosynthesis remains to be understood. In my investigation I am going to establish the effect of changing light intensity on the rate of photosynthesis.

Less than 1% of the water absorbed by a plant is used in photosynthesis. Above this temperature, there is an abrupt fall in the rate and the tissue dies at 43°C. For instance, with lower concentrations of the limiting factor e. If it is cold enough for water to freeze it can be very harmful to a plant. Only red and blue light are effective for photosynthesis.

Carbon sources are used to provide carbon as a macronutrient to micro-organisms to enable them to grow and reproduce rapidly. You can develop more accurate measures by collecting the gas produced and measuring the volume of gas produced each minute or over longer time periods. In these regions, chlorophylls absorb maximal light. To achieve optimum growth of some plants, farmers keep them in greenhouses that regulate conditions such as humidity and temperature. Materials: two 600 mL beakers 1.

Therefore, rate of transpiration increases. Oxygen is produced from the water and it is a waste product so it is released into the air. Group 4, Group 5 and Group 6 Question 2: The higher the temperature, the greater the rate of photosynthesis. These sugars are then used by the plant as energy for any number of things. I would then fill the boiling tube 43ml of water, put the pondweed in it and place it in the clamp. Glucose is produced and is converted into Starch to be stored.

These factors influences the diffusion of carbon dioxide thorough the stomata. Then it will start decreasing and be very low almost 0 through the 500-550nm green light and then it will increase again peaking at about 700nm red and yellow light. Introduction: Photosynthesis is the major source of energy for practically all plants living in sunlight. Although the light dependent reactions of photosynthesis are not affected by changes in temperature, the light independent reactions of photosynthesis are dependent on temperature. Examples of autotrophs are green plants, algae, bacteria, etc.

Repeat twice and calculate a mean bubble count — number of bubbles per minute. Whats more, different types of carbohydrates release various amounts of energy during fermentation. In this study, we try to prove whether or not there is a significant statistical difference between the level of carbon dioxide and the rate of photosynthesis. They need water to support the plant to face the sun as well as a raw material of photosynthesis. Firstly, I put Sodium Bicarbonate in the boiling tube to enrich the water with Carbon Dioxide so more Oxygen bubbles would be produced.

Plants from regions of warmer climates can successfully grow in colder regions by using greenhouses. By understanding the factors that affect the rate of photosynthesis they can do work to try and increase the rate of photosynthesis to increase the yield of a crop. Prepare your answers and get ready to share your answers with the class. Availability of nutrients: On a deeper level, other factors like amount of chlorophyll, availability of nutrients e. Glucose is a small, soluble molecule which is useless for a plant to use as energy but it converts it into Starch, which is a large and insoluble molecule, so it can be stored for to be converted back into Glucose. The Plan In my experiment I am going to see how light affects the rate of photosynthesis.

Hypothesis: If one carbon dioxide source is removed, then the rate of photolysis will remain constant because carbon dioxide is not needed for photolysis. This substance is essential for photosynthesis. The rate of photosynthesis in relation to temperature forms a bell curve. If the temperature is too cold or too hot, the enzymes might deactivate, or their efficiency will be inhibited. Too much light at a high intensity can damage chloroplasts. By Robert Frank 2007 limiting factors are the required factors whose supply most strongly influences or affect the rate of a reaction. This is because photosynthesis is a reaction, which needs energy from light to work, so as the amount of energy available from light increased with the rise in light intensity, so did the amount of oxygen produced as a product of photosynthesis.
