Answer:
Plants can be woody-stemmed such as shrubs and trees. Or they can be herbaceous, or herblike, in their stems. A woody's above-ground parts go dormant each year, but don't die. All or most of herbaceous plant above-ground parts die each year. It's all if the plant's an annual, and lives just one year. It's most if the plant's biennial or perennial, and lives more than one year. Examples of herbaceous plants are ferns, flowers, grasses, herbs, vegetables, and weeds.
