Detailed explanation-1: -Annual plants complete their life cycle in one growing season. Biennial plants are planted in one year, grow through the year, grow on and flower during the next year. Perennial plants grow strong year after year. They germinate, grow, bear fruits and flowers, and die off in the same year.

Detailed explanation-2: -The difference between annual, perennial, and biennial plants comes down to how many years they live. Annuals live for one year, biennials live for two years, and perennials live more than two years-from three years to hundreds of years.

Detailed explanation-3: -biennial, any herbaceous flowering plant that completes its life cycle in two growing seasons. During the first growing season, biennials produce roots, stems, and leaves. During the second growing season, they produce flowers, fruits, and seeds, and then they die.

Detailed explanation-4: -Annuals. Annuals take a single year to complete a full life cycle. Most are planted in the spring, bloom in the summer, and die in the fall. A few, known as winter annuals, germinate in the later summer and autumn, are dormant during the winter, and grow during the next spring and summer.

Detailed explanation-5: -Perennials-especially small flowering plants-that grow and bloom over the spring and summer, die back every autumn and winter, and then return in the spring from their rootstock or other overwintering structure, are known as herbaceous perennials.
