For a seed to bear life, it must first fall to the ground and die. It is through the process of dying that the seed bears life and is transformed into a fresh new plant. How is this possible? Well, it is true that the seed has to first die and this happens only after the seed has matured on the parent plant. Mesmerizing ain’t it? Well, let’s see how the process of growth actually takes place.
Just like we humans need oxygen, food and water to foster our growth, plants too need nutrients to grow. Like human growth, plant growth also takes place primarily through the process of cell division.
Growth as we all know, is a process of irreversible increase in mass that results from cell division and cell expansion.
To aid the process of germination, a seed requires nutrient-rich soil, adequate sunlight, and sufficient water. Besides, favorable temperatures .
