BIOFERTILIZER: The pathophysiology of the Tuberculin reaction is explained thus: M. Tuberculi are engulfed by macrophages after being identified as foreign‚ but due to a self- preserving mechanism peculiar to TB it is able to block the fusion of the phagosome within which it is existing with the lysosome which would destroy it. So it can continue existing and replicating within the immune cell designed to destroy it. After several weeks‚ the immune system somehow [ mechanism as yet unexplained]

The seeds are then covered with more dirt and connected to a cup full of water through a wick. The soon to be plant is then placed under light for 24 hours. After this the plants with the highest amount of trichome numbers are found and kept. When flowers are present‚ the selected plants are cross pollinated with a pollinating
