    produced increases‚ as the light intensity increases‚ but only to a point. I predict this will happen because the plant will have enough carbon dioxide and water to keep up with the amount of light that there is. When there is less light intensity‚ photosynthesis will happen at a slower rate because gradually there will not be enough sunlight as there is carbon dioxide and water. APPARATUS: lamp x 1 beaker x 1 (1L) test tube x1(up to the top) water 500ml(up to

    CIGARETTE SMOKE TO PHOTOSYNTHESIS Increased Carbon Dioxide Smoke of all kinds‚ including cigarette smoke‚ increases the amount of carbon dioxide where it is present (since smoke is itself produced via combustion). Plants use carbon dioxide to make sugars (during photosynthesis). Its increased abundance‚ therefore‚ makes it easier for the plant to obtain. Thus‚ smoking near a plant actually makes it easier for that plant to obtain much-needed carbon dioxide. Hampering Photosynthesis At the same

    for the most part could have easily been recycled. This is eating away at our ozone layer which protects us from the sun that at its core burns twenty-seven million degrees Fahrenheit and in return we are seeing melting ice caps which stores carbon dioxide‚ a gas trapped within them and is being released into our atmosphere‚ thus causing sea levels to rise at an even greater rate. We are cutting down the trees that naturally take in our waste product so it will not aid in diminishing us as a race
