What is the term for the lifetime of a plant from germination to death?

The term that accurately describes the lifetime of a plant from germination to death is "plant lifecycle." This concept encompasses all the stages a plant goes through, including germination, growth, reproduction, and eventually senescence and death. Understanding the plant lifecycle is crucial for horticulturists and cultivators, as it helps them recognize the various phases of plant development and manage care practices accordingly.

While terms like "plant cycle," "plant growth stage," and "plant maturation phase" may describe specific aspects of plant development, they do not encompass the complete chronological journey of a plant's life. For example, "plant growth stage" would only refer to the periods of active growth, not including stages like germination or death. The broader scope of "plant lifecycle" makes it the most accurate choice for conveying the entirety of a plant's existence.
