Answer: it inhibits plant growth, leading to death.
Thus as this continues in the plant under investigations, the ells and tissues in all parts of the plants ( from the leaves to stem to roots) will die since food and mineral sources have been blocked.
This disrupts normal physiological mechanisms in plants.Thus nutrition, respiration, nervous coordination etc seized. Therefore normal growth will be inhibited,and eventually the plant dies.
Generally the same excitatory effects caffeine has on human physiology mechanism, is applicable to plants. It initially promotes accelerated growth of cells and tissues, and improves physiological process in the plant.But in high concentration, in extended period of time; its becomes toxic,; inhibits growth;leading to death.
