Detailed explanation-1: -Gymnosperm Sporophytes Sporophytes produce the haploid stage of the plant by undergoing meiosis, which results in a single pair of chromosomes for each generated cell. Meiosis ends with a megaspore or microspore, which develop into megagametophytes and microgametophytes respectively through mitosis.
