What is a key characteristic of a mature plant?

• A. It has just begun to sprout
• B. It is capable of reproduction
• C. It only grows roots
• D. It has not yet formed leaves

Answer: (B)

A key characteristic of a mature plant is its ability to reproduce. Mature plants have developed fully, reaching a stage in their life cycle where they can produce flowers or cones, which contain the reproductive structures necessary for the formation of seeds. This capability indicates that the plant has completed various life cycle stages, including germination and growth, and can contribute to the next generation of plants through sexual reproduction.

In contrast, a plant that has just begun to sprout is still in its early growth phase, and one that only grows roots or has not yet formed leaves lacks the structures needed for reproduction. These earlier stages of a plant's life cycle do not allow for reproduction, emphasizing that the ability to produce offspring is a defining trait of maturity in plants.
