Annual plant

Explanation:

An annual plant is called as such because it takes one year for it to go from seed, growth, seed production, then death. All parts of the annual plant dies  after one year, including the roots, the stems, and the leaves. The main purpose of the annual plants is to produce as much seeds that will survive. Unlike the perennial plants, they do not regrow seasonally.

the diploid number of chromosomes is sometimes represented by the symbol 2n. for the fruit fly, the diploid number is 8, which can be written as 2n = 8, where n represents twice the number of chromosomes in a sperm or egg cell.
