GERMINATION Meaning and
Definition
-
Germination is the biological process by which a seed or spore begins to sprout, leading to the development of a new plant. It is an essential stage in the lifecycle of plants, enabling the propagation and continuation of their species.
During germination, the seed absorbs water through its outer coat, which triggers a series of biochemical reactions within the seed. Enzymes are activated, leading to the breakdown of stored nutrients such as starches and proteins. These nutrients provide the necessary energy and resources for the growth of the young plant.
As a result of these internal processes, the seed begins to swell and the outer coat softens. This allows the seedling to emerge, sending a root downward into the soil and a shoot upward into the air. The root absorbs water and nutrients from the soil, while the shoot grows leaves to capture sunlight for photosynthesis.
The conditions required for successful germination vary depending on the plant species, as some seeds may need specific temperature, moisture, or light levels. For example, some seeds need exposure to cold temperatures, a process known as stratification, to break dormancy and initiate germination.
Germination is a remarkable phenomenon that showcases the plant's ability to regenerate and give life. It is an essential step in agricultural practices, gardening, and the restoration of ecosystems, as it allows for the establishment of new plants and ensures the continuation of plant species.
