articles on acidity and photosynthesis

I recently did an experiment testing photosynthesis in soybean plants after simulated acid rain. We had three treatments one was a control which recieved no acid solution, a soil pH treatment in which the acidic solution was only added to the soil and a foliar pH treatment in which, only the leaves were sprayed with an acidic solution. We then are going to see which treatment had a greater effect. For my report I need to find three journal articles (primary literatue) that are relevant to the experiment and I am having some trouble finding anything of use to me. I was wondering if someone could help me find some articles.

articles on the effects of pH on photosynthesis and shoot growth in soybean plants

I recently did an experiment in my plant physiology class to see how pH affects the photosynthetic rate and growth in soybean plants. We did our experiment mainly to see if an acidic pH has a greater or lesser effect when sprayed directly to the leaves or when poured in the soil. To do so we had three different plants each recieving a different treatment. The control plant which did not recieve any acidic solution, a foliar pH treatment plant in which the leaves were sprayed with an acidic sol'n and a soil pH treatment plant in which we poured an acidic sol'n into the soil. I am having trouble finding useful journal articals that I can access relating to this experiment. I was wondering... click for more

Photosynthesis

Why do photosythetic cells in eukaryotes also contain mitochondria?

Plant biotechnology, domesticated species.

1. You are a geneticist working for a firm that specializes in plant biotechnology. Explain what specific parts (fruit, seeds, stems, roots, etc.) of the following plants you would try to alter by genetic engineering, what changes you would try to make, and why, on a) corn, b) tomatoes, c) wheat, and d) avocados. 2. Only a few hundred of the hundreds of thousands of species in the plant kingdom have been domesticated for human use. One example is the almond. The domestic almond is nutritious and harmless, but its wild precursor can cause cyanide poisoning. The oak makes potentially nutritious seeds (acorns) that contain very bitter-tasting tannins. If we could breed the tannin out of a... click for more
