Give a scientific reason: Haploid parents produce haploid gametes.

(N/A) In haploid organisms,the plant body is $n$. Since the organism is already haploid,it cannot undergo meiosis to produce gametes because meiosis reduces the chromosome number by half. Therefore,haploid organisms produce gametes through mitosis,which is an equational division. This ensures that the gametes maintain the same haploid $(n)$ chromosome number as the parent.
