The significant abiotic by-product of photosynthesis is oxygen. The main product of the process is glucose, which the plant uses as food. The general equation for photosynthesis is:
6CO2 (carbon dioxide) + 6H2O (water) = C6H12O6 (glucose) + 6O2 (oxygen)
It can be seen that plants are important to sustain life because they reduce the earth's carbon dioxide, and replace it with oxygen.
Vascular tissue is located inside the pericycle of a root, which I believe would be considered the inner layer.
The temperature of the earth
