빛의 세기, 이산화탄소의 농도, 온도와 광합성률과의 복합적 관계를 설명하는 광합성 모델 수식의 개발

Abstract

By analyzing precedented studies about photosynthesis, we found that photosynthesis is a basic concept to understand many aspects and functions of biological phenomena and to study biology, and it's a very important and major theme in the present middle school and high school biology. Among the contents of photosynthesis, environmental factors affecting the rate of photosynthesis is one of the major topics, but the exact data that represent the relationship of photosynthetic rate and environmental factors (light intensity, CO2 concentration, and temperature) have not been reported until now. Thus we developed a photosynthetic numerical model with which we could calculate the number of bubbles when light intensity, CO2 concentration and temperature are given. In order to develop this numerical formula, we carried out photosynthesis experiments several times using waterweed, Rotala rotundifolia which produces oxygen bubbles well, and used DataFit and Sigmaplot 2000 to construct this photosynthetic numerical model.
