The photosynthetic strategy of better vegetation converts carbon dioxide, water, and, mild quanta into decreased sugars. The enzymes which catalyze this conversion are contained in the chloroplasts and will be regarded as cut up into certain teams. in a single staff are the enzymes of the IIlightll reactions, which harvest the sunshine, oxidize water and generate energy-rich intermediates, ATP and NADPH. those intermediates plus carbon dioxide are the substrates for the second one workforce, the IIdarkll reactions or Cal vi n cycle, which produce the lowered sugars. The chloroplast is totally bounded by way of an outer membrane. there's a separate, hugely convoluted membrane approach, the thyla­ koid approach, enclosed in the chloroplast. The enzymes of the sunshine reactions are bodily linked to the thylakoid mem­ branes, whereas the Calvin cycle enzymes are free-floating in the stroma, or soluble a part of the chloroplast (Fig. 1).

Thus, leaves with stomata on only one side can be characterized by K=O or K=infinity. The second observation is of the error caused by the assumption used to get from equation 27 (1§) to QQuation (16). A~ long a~ th@ bDundary laYQr r@sist~ne~ ;~ less than 1/5 of the leaf resistance, the error will be negligible (a fraction of a percent). If rh approaches rL, however, the error approaches 100% when K=O. 2 Photosynthesis The apparent photosynthetic rate A (mass CO 2 area- 1 time -1) measured in a closed chamber is expressed by: A= v dqc - ( ( 17) a dt where q is the concentration (mass volume-I) of the CO 2 in the air.

00529 a (t2 - tl) (Ta + 273) (19) where A is in (mg CO 2 m- 2 s-I), Cl and C2 are lnitial and final concentrations of C02 in the chamber expressed in volumetric ppm, Ta is the mean air temperature during the measurement interval. 3 Desiccant Correction Normally. the LI-6000 is operated with magnesium perchlorate desiccant in the air stream ahead of the C02 analyzer. This is done to remove all water sensitivity and dilution effects from the C02 analyzer readings. Because the LI-6000 operates in a closed system, however, the presence of the desiccant causes dry air to be returned to the leaf chamber.

The procedure for measuring C02 assimilation by the enclosed material depends on the type of gas exchange system employed. Three basic configurations of systems have been used and these are considered below. In essence, all three make use of the fact that the net rate of C02 assimilation by the plant material enclosed is equal to the product of the net rate of air flow and the change in C02 mole fraction across the chamber. 4 Gas Exchange Systems and Equations for Flux Determinations Closed systems.
