Question

What is the quantitative and qualitative analysis of effect of increased CO2 concentration and increased temperature on the growth of Arabidopsis Thaliana?

Answer 1

Carbon dioxide is used to make sugar in thephotosynthesis reaction. The concentration ofcarbon dioxide in the Earth's atmosphere varies between 0.03% and 0.04%. An increase in the concentration of carbon dioxide gives an increase in the rate of photosynthesis.

Seedlings of Arabidopsis thaliana grown at 25°C responded to a change in growth temperature by changing their elongation rate within the next 150 min. Regardless of whether the new temperature was higher or lower than 25°C, the seedlings grew slower after the transfer at all testedtemperatures.
