• B. Do not die after seasonal production of fruits.
• C. Invariably show asexual reproductive structure.
• D. Always have underground perennating structure.

Answer 1

The correct option is B Do not die after seasonal production of fruits.

The main difference between the biennials and perennial plants is that the perennials do not die after seasonal production of fruit. A biennial plant is a flowering plant that takes two years to complete its biological lifecycle. In the first year, the plant develops leaves, stems, and roots then it enters a period of dormancy over the colder months. Usually the stem remains very short and the leaves are low to the ground, forming a rosette. Many biennials require a cold treatment, or vernalization, before they will flower. During the next spring or summer, the stem of the biennial plant elongates greatly. The plant then flowers, producing fruits and seeds before it finally dies. There are far fewer biennials than either perennial plants or annual plants. A perennial plant or simply perennial is a plant that lives for more than two years.
Therefore, the correct answer is option B.
