Which statement best describes introduced plants?

• A. Introduced plants come from other parts of the world or country, usually through human activity.
• B. Native plants come from the area and are not introduced by human activity.
• C. Introduced plants are always beneficial for pest control.
• D. Native plants are always annuals.

Answer: (A)

Introduced plants are species that did not naturally occur in the area but were brought from other regions, typically by human activities such as trading, gardening, or transport. This distinction from native plants is important because introduced species originate outside the local ecosystem, and their presence is linked to human movement of species. While some introduced plants may aid pest control in certain situations, many can become pests themselves or disrupt native communities, so they are not inherently beneficial. Also, native plants originate in the area and aren’t introduced by humans, and natives can be annuals, perennials, or biennials, so the idea that natives are always annuals is incorrect.
