Plants with two-year life cycles are called biennials.
Biennial plants have a unique life cycle that spans over two years. Here is a detailed explanation of their life cycle:
1. First year:
- During the first year, biennial plants primarily focus on vegetative growth.
- They develop a rosette of leaves close to the ground.
- The main goal is to store energy in their roots or stems for the upcoming flowering and seed production in the second year.
- Examples of biennial plants include carrots, onion, and parsley.
2. Second year:
- In the second year, biennial plants go through the reproductive phase.
- They produce flowers and set seeds.
- After flowering and seed production, most biennials die.
- However, some may live for an additional year or two, depending on the species.
3. Life cycle completion:
- Biennial plants complete their life cycle within these two years, from germination to seed production.
- The seeds produced by biennials are usually dispersed to ensure the survival and continuation of the species.
Summary:
Biennial plants have a unique life cycle that spans over two years. During the first year, they focus on vegetative growth, while in the second year, they reproduce and set seeds. Some examples of biennial plants include carrots, onion, and parsley.
