This scaling requires using the leaf model over a wider temperature range than that for which the model was originally parameterized. Empiric. The immediate post-illumination respiratory O2 uptake rate (THE AUTHORS') is higher in the beginning of the batch culture when the specific growth rate is highest, and this suggests that respiration could fulfill the maintenance requirements of the microalgal cells. O2 exchange was measured with a 5-chamber data-logging apparatus and ETR with a submersible pulse amplitude modulated (PAM) fluorometer (Diving-PAM). Having said that, the use of these embryos for research and manipulating them go against morals and ethics. If the stomata is closed, the oxygen from photosynthesis will build up inside the leaf while the carbon dioxide will not get into the leaf.
