Whether nickel is an essential element for barley. Given: Barley plants were grown over three generations in the below-mentioned concentrations. All the seeds from each plant were harvested and were examined for their number and mass. Some seeds out of the total harvest were grown in nickel-free conditions to test their germination. Introduction: Plant growth is dependent on the availability of essential nutrients. The scarcity of nutrients, which impairs or stunts the growth of the plant, leads to many diseases and in extreme cases, plant’s death. Some nutrients like nitrogen and calcium are required by the plant in larger concentration and are called macronutrients. Micronutrients (like zinc and copper), on the other hand, are only required in minute quantities by the plant, but are still essential for the plant growth.

Expert Solution & Answer

Explanation of Solution

Through the table, it can be gathered that concentrations of 0 μM and 0.6 μM of nickel in the growth solution did not witness a vast difference in the seed set. A nickel concentration of 1.0 μM, on the other hand, showed an increase in the harvest by 20 and an increase in mass by 1.1 g dry weight with respect to the control.

On testing for germination, the results showed drastic differences. Only 20% of seeds treated with 0 μM nickel germinated while 40–80% of seeds treated with 0.6 μM nickel showed germination. Maximum germination (beyond 90%) of seeds was observed in the third set of seeds that were treated with 1.0 μM nickel solution.

Conclusion

Therefore, on analyzing the results from the table and the graph, it can be concluded that nickel is essential for the growth of barley. In presence of optimum nickel quantity, seed set is enhanced and percent germination also increases. On the other hand, it is not a major determinant of mass and the number of seeds produced.

engineered constructs that consist of hollow fibers are acting as synthetic capillaries, around which cells have been loaded. The cellular space around a single fiber can be modeled as if it were a Krogh tissue cylinder. Each fiber has an outside “capillary” radius of 100 µm and the “tissue” radius can be taken as 200 µm. The following values apply to the device:R0 = 20 µM/secaO2 = 1.35 µM/mmHgDO2,T = 1.67 x 10-5 cm2/secPO2,m = 4 x 10-3 cm/secInstead of blood inside the fibers, the oxygen transport and tissue consumption are being investigated by usingan aqueous solution saturated with pure oxygen. As a result, there is no mass transfer resistance in the synthetic“capillary”, only that due to the membrane itself. Rather than accounting for pO2 variations along the length ofthe fiber, use an average value in the “capillary” of 130 mmHg.Is the tissue fully oxygenated?
