Aim I am going to investigate the light to find the effects of light intensity in the rate of the photosynthesis. Introduction Light is one of the most important substance o photosynthesis. Photosynthesis increases depend on the intensity of light. We can recognise whether bubbles occur photosynthesis. Hence, I predict that as the light intensity is increases, the number of bubbles is going to increase. Apparatus 1) One 1 litre of beaker 2) 800 ml of water 3) ...read more.


Put a lamp 1m from the beaker. 5) Put a metre rule for measure the distance between lamp and beaker. 6) Cover the beaker by a box except a side which the light goes in. 7) Approach the lamp 5cm to the beaker every minute. 8) Measure the number of bubbles for every minute. Result Distance from the pondweed Number of bubbles in the First experiment Number of bubbles in the Second experiment Average 100 12 3 7.5 95 12 4 8 90 13 6 9.5 85 14 8 11 80 14 8 11 75 17 9 13 ...read more.


In other words, when the light intensity is increases, the photosynthesis is increases. Evaluation I did my experiment very keenly to make accurate. First, I did my experiment because it can have different result with same environment. Hence, I calculated the average of two results and drew the graph of result. Also, I used counter, which was for count the number of bubbles to measure accurately. Therefore, I could get good result from my method. Through this experiment, I could improve my biological observational faculty and importance of photosynthesis in Biology. ...read more.

    Investigation to find out how light intensity effects the rate of photosynthesis

    4 star(s)

    Water Flowering plants that live on land get the water for photosynthesis through their roots from water in the soil. The water travels through the plants in veins called vascular bundles. Plants that live in water get it from their surroundings.

  2. How temperature affects the rate of photosynthesis.

    obtain reliable results, but during the time given, only three repeats were possible. This can be said to be a limitation as a higher number of repeats would have provided far reliable results and the changes could have been studied in greater depth.

  1. The effects of light intensity on the rate of photosynthesis.

    This can be caused by disease, mineral deficiency, and the age of the plant. Iron, magnesium, nitrogen and sunlight are essential for chlorophyll production, so a lack of any one of these can lead to yellowing of the leaves6. Water is necessary for most cell processes, which makes it difficult

  2. In this coursework I am going to find out if trees modify the environment.

    Trees also hold the soil together to prevent soil erosion. I think there will be less living ground cover on the path because when humans walk on the path they trample on and kill any living ground cover. There is also more soil erosion on the path because the top soil comes off when humans are walking on it.

    8. The results for biotic index and diversty index will be proved by checking out the abiotic factors of oxygen concentrations, light availability, nitrate levels affecting the fresh water stream. 9. BOD will be measured by using an oxygen meter at all selected sites in the following way: * Two water samples will be collected from the same site.
