At what growth stage does the embryo develop into a new plant?

The embryo develops into a new plant during the germination stage. Germination is the process that occurs when a seed absorbs water, swells, and eventually breaks through the seed coat. This stage is critical as it marks the transition from dormancy to active growth, allowing the embryo to utilize stored nutrients to support its initial development into a seedling.

During germination, the embryo begins to grow and unfolds into a new plant structure. The root emerges first, followed by the shoot, which will eventually develop into the stem and leaves of the plant. This is the key moment when the potential of the seed is realized as it transitions from a dormant state to an active growing organism.

In contrast, the vegetative stage refers to the growth phase following germination when the plant develops leaves and stems. The reproductive stage involves the processes responsible for producing flowers and seeds. Ripening is the final phase when seeds mature and prepare for dispersal. Thus, germination is uniquely defined as the point when an embryo actively begins developing into a new plant.
