Final answer:
The distribution of plant types based on their life cycles is Perennials: 25 plants, Biennials: 60 plants, and Annuals: 72 plants, which corresponds to option A.
Step-by-step explanation:
The question is regarding the distribution of plant types which are categorized based on their life cycles. There are three main types of life cycles in plants: annuals, biennials, and perennials. An annual plant goes through its entire lifecycle in one season, from germination to the production of seeds. Arabidopsis, or mouse-ear cress, is an example of an annual. A biennial plant such as the carrot completes its lifecycle in two seasons. In the first season, it grows vegetatively, and in the second, it flowers and reproduces. Perennials like the magnolia can live and flower for more than two years. Given these definitions, the correct answer to the distribution of plant types is:
Perennials: 25 plants, Biennials: 60 plants, Annuals: 72 plants
This correlates with option A): Perennials: 25 plants, Biennials: 60 plants, Annuals: 72 plants.
